Newly released photographs of the sun captured during the Aug. 12 total solar eclipse reveal the sun's outer atmosphere in unprecedented detail.

The images, released by researchers working as part of the Solar Wind Sherpas project coordinated by the University of Hawaii, also show rare structures in the solar wind known as smoke rings. Named for their resemblance to the circles blown by smokers, these vortices were first identified in solar eclipse photographs captured in 2008. The researchers had long struggled to explain the processes behind their formation. They now know the rings are a result of the temperature differences in the coronal plasma and spread along the sun's magnetic lines deep into interplanetary space.

"This year, we have managed to capture those smoke rings really well," Miloslav Druckmüller, a professor of mathematics at the Brno University of Technology in the Czech Republic, who leads the image processing efforts for the Solar Wind Sherpas Team, said in a statement. "They are beautifully twisted vortices and there are very many of them in the corona."

The images, taken from the Pico Trigaza mountain in Spain, also reveal a giant coronal hole — an opening in the sun's magnetic field lines — through which solar wind can escape more readily at very high speeds of up to 500 miles per second (800 kilometers per second).

Coronal holes are cooler regions in the sun's atmosphere that appear darker in extreme ultraviolet and X-ray images taken by probes in space. They form in regions where the sun's magnetic field lines extend outward into space rather than looping back to the surface, allowing high-speed solar wind to escape. These structures can persist for weeks or even months.

Solar eclipse photography provides a unique vista into the processes taking place in the sun's upper atmosphere, the corona, which remain hidden even to cutting-edge space-based observatories.

Space probes and astronomical telescopes on Earth rely on instruments known as coronagraphs to view the corona. As the corona is a million times dimmer than the sun's surface, researchers need to obscure the visible solar disk with an occulter to view it. This occulter, located inside the telescope, has to cover a larger area than just the solar disk itself to protect the images from the effects of diffraction.

During a total solar eclipse, the moon naturally blocks the sun's bright disk, allowing scientists to capture exceptionally detailed views of the inner corona that are difficult to obtain with conventional coronographs.

Black holes more massive than entire galaxies are not a major component of the mysterious dark matter that's thought to make up most of the matter in the cosmos, a new study finds.

For decades, to explain why galaxies do not spin apart at the speeds at which they whirl, scientists have suggested the existence of an unseen substance known as dark matter, whose gravitational pull helps keep galaxies together. Dark matter is thought to make up about five-sixths of all matter in the universe.

Much remains unknown about dark matter, however — including whether or not it actually exists. Black holes make good potential contenders for dark matter, since they are extremely massive and are difficult to spot in the dark depths of space.

In the new study, researchers investigated whether dark matter could be made of "stupendously large black holes," ones with masses greater than 100 billion times the mass of the sun. Stupendously large black holes greater than 1 million billion to 10 million billion suns in mass would be heavier than entire galaxies.

So far, astronomers have not detected any stupendously large black holes — currently, the largest black hole known may weigh about 36 billion suns. Since researchers have not seen any even after looking at many galaxies, the new study noted they cannot make up all of dark matter — but team members wondered if the exotic objects still might constitute a significant portion of the puzzling substance.

Often, dark matter is thought of "as a fine dust spread everywhere," study co-author Christopher Gerlach, a theoretical physicist at the Mainz Institute for Theoretical Physics in Germany, told Space.com. However, if dark matter is packed into a handful of gigantic objects such as stupendously large black holes, "the universe becomes grainy on very large scales. And we can check that."

Specifically, the scientists analyzed the light from the dawn of the universe, study co-author Yann Gouttenoire, a theoretical physicist at the Mainz Institute for Theoretical Physics, told Space.com.

For the first 380,000 years after the Big Bang, the cosmos was filled with a hot plasma in which light was trapped. Eventually, the expansion of the universe let the cosmos cool enough for the plasma to largely dissipate and form atoms. This in turn let light shine freely, "and that light is still arriving today," Gerlach explained. "We call it the cosmic microwave background, a snapshot of the infant universe covering the whole sky."

The temperature of the cosmic microwave background "varies from place to place by about one part in 100,000," study co-author Antonio Iovino, a theoretical physicist at New York University, Abu Dhabi, in the United Arab Emirates, told Space.com. "That pattern tells us how matter was spread back then."

Analyzing the cosmic microwave background revealed it is not grainy the way stupendously black holes would have made it. "So these black holes can't be a significant part of the dark matter," Nicholas Leister, a theoretical physicist at the Mainz Institute for Theoretical Physics, told Space.com.

The researchers cautioned that the new findings do not suggest that stupendously large black holes cannot exist, only that they do not make up a major fraction of dark matter. They added that another candidate for dark matter — relatively tiny black holes the size of asteroids — might potentially exist. They are now investigating whether they can rule out such itty-bitty black holes as a major constituent of dark matter.

The scientists detail their findings in a study that will be published Oct. 26 in the journal Physical Review Letters.

I've spent years chasing the northern lights across the Arctic, from the mountains of Swedish Lapland to the dramatic Norwegian fjords.

If there's one thing I've learned, it's that choosing where to see the northern lights is about much more than simply heading as far north as possible. Whether you're on the hunt for somewhere that offers the best chance of clear skies, the most dramatic scenery or a plethora of winter activities to keep you warm, choosing the right destination can make a big difference, especially as auroras are never guaranteed.

My biggest piece of advice? Choose somewhere you've always wanted to visit regardless of whether the northern lights might appear. That way, the auroras become the icing on the cake rather than the sole measure of a successful trip.

From my personal favorites in Scandinavia to some of North America's most established aurora hotspots, here are seven of the best places to see the northern lights this 2026/27 season.

Best places to see the northern lights at a glance

Abisko and Kiruna, Sweden: Best for a short northern lights trip

Best time to visit: September to early April

Swedish Lapland holds a particularly special place in my heart. It's where I saw the northern lights for the very first time, during a trip to Kiruna in February 2023.

I'd only booked two nights in Kiruna, one of which included a northern lights tour with Anders from Outdoor North 67º. Talk about putting all your eggs in one basket! But the gamble paid off, and I was treated to a spellbinding display of auroras dancing across the Arctic sky. I've been hooked ever since.

Kiruna offers a wide range of accommodation, restaurants and activities, making it a convenient base for exploring the region. From here, you can join guided aurora tours, visit the famous Icehotel in Jukkasjärvi or head into the wilderness for dog sledding and snowmobiling adventures.

One of the region's biggest draws is Abisko National Park, around 60 miles (100 kilometers) northwest of Kiruna. Abisko is famous for its so-called "Blue Hole", a local weather phenomenon in which the skies above the national park can be clear, even if the surrounding region (and weather forecast) is cloudy. This is partly thanks to the surrounding mountains, which create a rain shadow effect, reducing the precipitation in the area.

And if you're visiting Abisko, I'd highly recommend taking the chairlift up Mount Nuolja to the Aurora Sky Station. The views across Abisko National Park and the surrounding mountains are spectacular. Just be sure to check the chairlift's operating dates and times before visiting, as it doesn't run throughout the entire season.

My tip: Although my two-night gamble paid off, I wouldn't recommend relying on such a short window if seeing the northern lights is your main goal. If possible, give yourself at least three or four nights to improve your chances of clear skies and aurora activity.

Tromsø, Norway: Best for a city break

Best time to visit: September to early April

If you want to experience the northern lights without giving up the comforts of city life, Tromsø is hard to beat.

Located high above the Arctic Circle in northern Norway, Tromsø sits beneath the auroral oval, the region surrounding Earth's magnetic poles where auroras occur most frequently.

What I particularly like about Tromsø is that it offers the best of both worlds. You have a lively city with excellent restaurants, cafes, shops, museums and accommodation, while spectacular mountains and wilderness are only a short journey away.

There's also a huge range of northern lights tours available, from small-group photography excursions to longer aurora-chasing adventures.

My tip: Tromsø is ideal if you want to combine northern lights hunting with a city break holiday. I'd recommend booking at least one guided aurora tour, particularly if the local weather forecast looks challenging.

The Norwegian coast: Best for a scenic Arctic voyage

Best time to visit: September to March

If there's one northern lights experience I'd encourage people to consider, it's sailing along the Norwegian coast.

I've been fortunate enough to travel along this extraordinary coastline on several occasions, and there's something very special about watching the northern lights from the deck of a ship, surrounded by good company, mountains, fjords and the dark Arctic sea.

Operators such as Hurtigruten and HX offer voyages along the Norwegian coast, combining opportunities to see the northern lights with some of the most spectacular scenery in Europe. While Hurtigruten operates coastal voyages calling at towns and communities along the route, HX offers expedition-style experiences with a focus on exploring the natural environment.

Rather than staying in one location, you'll travel through different coastal landscapes, with opportunities to experience Arctic wildlife, local culture and winter excursions along the way.

And then, of course, there's the possibility of the northern lights appearing overhead.

However, there's an important trade-off. Unlike a land-based aurora chase, a ship can't simply drive inland to escape coastal cloud cover. You're largely dependent on the weather along your route, although traveling through different regions over several nights gives you multiple opportunities.

Hurtigruten also offers a Northern Lights Promise on qualifying voyages, providing a complimentary return voyage if the lights aren't officially sighted during your trip. Be sure to check the eligibility requirements and terms before booking.

My tip: Choose a Norwegian coastal voyage because you want to experience the coastline itself. The scenery, communities and Arctic landscapes make it a remarkable journey regardless of auroras.

Finnish Lapland: Best for a winter wonderland getaway

Best time to visit: September to March

If you dream of a northern lights holiday involving snow-covered forests, cozy cabins and perhaps even watching auroras from a glass-roofed igloo, Finnish Lapland could be the perfect choice.

Northern Finland lies beneath the auroral oval, making it a popular destination for aurora chasers. Places such as Inari, Saariselkä and Ivalo offer excellent access to dark skies and Arctic wilderness.

Rovaniemi, the official hometown of Santa Claus, is another popular option, particularly for families, although it's worth traveling away from the city's lights for the best views.

My tip: For a quieter, more wilderness-focused escape, I'd look at northern Lapland around Inari or Saariselkä. If you're traveling with children or want a more activity-packed holiday, Rovaniemi may be a better fit.

Iceland: Best for volcanoes, glaciers and natural wonders

Iceland is one of the most extraordinary places I've ever visited. What makes it particularly special is the sheer variety of landscapes packed into one country, from towering waterfalls and vast glaciers to active volcanoes, black-sand beaches and steaming geothermal pools. There's an incredible amount to explore between northern lights hunting sessions.

But there's a catch.

Iceland's notoriously changeable weather and frequent cloud cover can make aurora hunting challenging. For that reason, I'd consider Iceland one of the riskier destinations on this list if your main objective is seeing the northern lights.

Iceland's landscapes provide some of the most spectacular backdrops imaginable for aurora photography, and when the skies cooperate, the results can be breathtaking.

The key is flexibility. I'd recommend giving yourself several nights and booking a northern lights tour that can travel in search of clearer skies rather than relying on a single fixed viewing location.

And while I've visited Iceland myself, I haven't been there specifically to chase auroras. What I can say from experience is that the country is absolutely worth visiting regardless of whether the lights appear.

My tip: Visit Iceland because you want to see Iceland, not just the northern lights. Explore its waterfalls, glaciers and volcanic landscapes, and treat any aurora sightings as an extraordinary bonus.

Fairbanks, Alaska: Best for a U.S. aurora getaway

Best time to visit: September to March

For U.S.-based travelers dreaming of seeing the northern lights, Fairbanks is a more convenient travel destination than Scandinavia.

Located in Alaska's interior, Fairbanks sits beneath the auroral oval. Its inland location is a major advantage compared to many coastal Arctic destinations; Fairbanks generally experiences less precipitation and more opportunities for clearer skies.

The official aurora-viewing season runs from Aug. 21 to April 21, providing a long window for planning a trip. However, if you're visiting in late August or early September, be prepared for some late nights. With daylight still lingering well into the evening, the sky may not become dark enough for good aurora viewing until around midnight or later.

The advantage of visiting earlier in the season is that temperatures are generally much milder compared to in the depths of winter. But if you would prefer longer nights and more opportunities to spot auroras, consider a trip between late September and March.

Yellowknife, Canada: Best for a Canadian aurora getaway

Best time to visit: Mid-August to late September and mid-November to early April

For Canadian travelers hoping to see the northern lights, Yellowknife offers an incredible aurora-viewing destination without the need to travel overseas.

Situated beneath the auroral oval, Yellowknife benefits from a relatively dry continental climate, with plenty of opportunities for clear skies compared with some coastal Arctic locations.

However, timing your visit carefully can make a difference. Although auroras are visible throughout the dark months, late October and early November are generally a less favorable period for a dedicated aurora trip. As temperatures drop, heavy cloud systems move through the area, making sightings more challenging. Indeed, some tour operators temporarily reduce their activities during this period. This is when the region receives most of its snowfall, so shifting your aurora viewing plans before or after this period gives you considerably better visibility.

My tip: Consider booking a multi-night package or several guided outings to give yourself more opportunities if the weather doesn't cooperate.

When is the best time to see the northern lights?

The northern lights occur throughout the year, but you need sufficiently dark skies to see them. That's why the main aurora tourism season across much of the Arctic runs from roughly late August or September through March or early April.

March and September are particularly good months for aurora hunting, thanks to a seasonal boost in geomagnetic activity around the spring and autumn equinoxes. This is partly explained by the Russell-McPherron effect, which describes how the changing orientation of Earth's magnetic field relative to the magnetic field carried by the solar wind makes geomagnetic disturbances more likely around the equinoxes. A 75-year study by retired NASA solar physicist David Hathaway shows that March has more geomagnetically active days than any other month of the year (with October a close second), according to Spaceweather.com.

But personally, I prefer hunting for auroras in the depths of winter, particularly December and January, when the long, dark nights give me plenty of opportunities to look for the lights. Yes, it's much colder, but I love the snowy Arctic landscapes, and I'd much rather be standing in a winter wonderland than battling driving rain!

Frequently asked questions

Just when you thought the sun might be taking a breather, it's unleashed another powerful eruption — and the northern lights forecast just got even more promising.

A fourth coronal mass ejection (CME) erupted from the sun on Oct. 8, during a powerful M-class solar flare from the restless sunspot region AR4549. That brings the number of CMEs potentially heading Earth's way to four, raising the possibility of further geomagnetic activity and aurora displays over the coming days.

Early analysis suggests the latest CME could potentially catch up with the third CME on its way towards Earth.

Will the northern lights be visible in the U.S.?

NOAA's aurora forecast suggests auroral activity could be enhanced across northern North America. Exactly how far south the aurora might appear remains uncertain and depends on how the incoming CMEs interact with Earth's magnetic field.

G2 geomagnetic storm conditions are forecast for Oct. 9 and during such storms, auroras have previously been observed as far south as New York and Idaho.

While northern U.S. states currently have the best prospects, skywatchers farther south shouldn't completely write off their chances just yet. With multiple CMEs approaching Earth in quick succession, there's still considerable uncertainty over how geomagnetic conditions will develop. If the incoming eruptions interact favorably with Earth's magnetic field, auroras could potentially reach much farther south than currently anticipated.

So if you're at mid-latitudes, make sure those aurora alerts are switched on and your camera batteries are charged. This could be an interesting few days for northern lights enthusiasts!

For real-time forecasts based on your location, consider using a space weather app. A great option is "My Aurora Forecast & Alerts" (available for iOS and Android). For a deeper dive into space weather conditions, "Space Weather Live" is another excellent choice (available for iOS and Android)

When should you look for the northern lights?

NOAA's latest 3-day forecast now places the strongest geomagnetic activity later on Oct. 9 than previously anticipated.

Minor (G1) geomagnetic storm conditions are forecast between 8 a.m. and 2 p.m. EDT (1200and 1800 GMT), with moderate (G2) conditions predicted between 2 and 8 p.m. EDT (1800 and midnight GMT).

Further activity is possible over the weekend, with NOAA currently forecasting minor (G1) conditions between 11 p.m. and 2 a.m. EDT on Oct. 10-11 (0300-0600 GMT Oct. 11).

For those wishing to catch some auroras, the advice remains the same! Keep your aurora alerts switched on and check conditions whenever skies are dark and clear. These forecast windows are not set in stone, particularly when multiple CMEs are involved!

When could the CMEs arrive?

This is where things get complicated.

Current modelling suggests the first CMEs could reach Earth on Oct. 9.

Space weather physicist Tamitha Skov notes that the two Oct. 6 CMEs could reach Earth in relatively quick succession, delivering a one-two punch to Earth's magnetic field. However, their journey may be influenced by the surrounding solar wind, making precise arrival times difficult to pin down.

The third CME could follow late Oct. 10 or early Oct. 11 (UTC), potentially prolonging unsettled geomagnetic activity and aurora prospects into the weekend.

And now there's a fourth CME to consider. Early analysis suggests this latest eruption is traveling faster than some of its predecessors, raising the possibility that it could catch up with the third CME before reaching Earth. The 'cannibal CME' could further complicate the timings and strength of resulting geomagnetic activity.

And remember, even an Earth-directed CME doesn't guarantee a spectacular aurora display. Much will depend on how the magnetic fields carried by these eruptions interact with Earth's magnetic field when they arrive.

With AR4549 still magnetically complex and facing Earth, more solar activity could be on the way. The sun sure is keeping us on our toes this week!

Editor's note: This article has been updated to include a fourth coronal mass ejection (CME) that erupted from the sun on Oct. 8, along with the latest geomagnetic storm forecasts and revised arrival estimates.

The sun unleashed a powerful eruption early on Oct. 6, launching a coronal mass ejection (CME) toward Earth — and it could give the northern lights a boost later this week.

NOAA's Space Weather Prediction Center (SWPC) has issued a moderate (G2) geomagnetic storm watch for Oct. 9, when the CME is expected to reach Earth.

The eruption accompanied an M1.4-class solar flare from sunspot region AR4549, which is currently positioned close to the center of the Earth-facing side of the sun.

Forecasters at Belgium's Solar Influences Data Analysis Center (SIDC) estimate the CME is travelling at around 560 km/s.

Current models put the CME's arrival in the early hours of Oct. 9 (UTC), although there is still uncertainty over the exact timing.

The U.K. Met Office currently predicts an arrival at around midnight EDT (0400 GMT), give or take 6 hours.

So don't set your alarm quite yet — CME arrival forecasts can shift by several hours as the eruption approaches.

Space weather forecasters are busy analyzing coronagraph observations and models to determine the CME's trajectory and speed, and updating the possible arrival time at Earth. That's when we'll have a much better idea of what this eruption could mean for the northern lights.

If a substantial part of the CME is Earth-directed, it could trigger a geomagnetic storm and send auroras into lower latitudes than usual. Just how impressive the display could be will also depend heavily on the magnetic orientation of the CME when it reaches Earth.

What could this mean for the northern lights?

NOAA's SWPC currently expects minor (G1) to moderate (G2) geomagnetic storm conditions on Oct. 9, with a G2 watch now in effect.

Geomagnetic storms are ranked on a scale 1-5, from G1 (minor) to G5 (extreme). G2 conditions correspond to Kp 6, and auroras have previously been seen as far south as New York and Idaho during storms of this strength.

This doesn't mean the northern lights are guaranteed to reach these states, nor does it mean they won't stretch even farther south. The extent of the show will depend on how the incoming CME interacts with Earth's magnetic field.

Even an Earth-directed CME doesn't guarantee an impressive geomagnetic storm and subsequent aurora shows. Much will depend on the strength and orientation of the magnetic field carried by the CME when it reaches Earth, particularly if it has a southward component that can couple efficiently with Earth's magnetosphere.

For now, aurora chasers should keep a close eye on the forecasts for Oct. 9.

When could the northern lights be visible?

NOAA's latest 3-day forecast shows:

• G1 conditions between 11 p.m. and 2 a.m. EDT on Oct. 8-9 (0300-0600 GMT)
• Possible G2 peak between 5 a.m. and 8 a.m. EDT (0900 and 1200 GMT) on Oct. 9.

These timings are estimates and could change as the CME approaches.

More solar activity could be on the way

And this might not be all the sun has in store for us.

At the time of writing AR4549 produced another M-class solar flare, an M1.8, just hours after the eruption we're currently keeping a close eye on.

Two prominent sunspot regions, AR4549 and AR4545, are currently facing Earth and have shown increasing flare activity. Any additional eruptions from these regions over the next few days could affect Earth. Meanwhile, coronal holes rotating across the Earth-facing side of the sun are expected to send further streams of fast solar wind our way, with another enhanced period of geomagnetic activity predicted around Oct. 11.

In other words, make sure those camera batteries are charged, your aurora alerts switched on and the coffee pot is full!

Editor's note: This story was updated at 4 a.m. EDT (0800 GMT) on Oct. 7 to include NOAA's Space Weather Prediction Center's G2 (moderate) geomagnetic storm watch for Oct. 9. We will continue to update this story as new forecasts become available.

Detective work by a team of space-weather experts has discovered the truth about a historical event that had been thought to be the first-ever case of technological disruption by geomagnetic activity from the sun, but has now been shown to have taken place seven years later.

From it being too hot or too wet to leaves on the track or cows on the line, there's a fine tradition of what the British public consider to be flimsy excuses for delays on the trains. Yet an 1871 edition of the journal Nature describes a very different event that caused a train departing Exeter, in Devon on the south-west coast of the U.K., to be delayed by 16 minutes: a solar storm that flooded the railway signals' electrical telegraph network with current.

"The Exeter train delay is a fascinating story because it sits right at the point where emerging technologies first began to encounter the realities of the space environment," said Jim Wild, who is a professor of space physics at Lancaster University and also the President of the Royal Astronomical Society, in a statement.

The event has frequently been cited as the first example of a solar storm disrupting technology on Earth, but when a team led by Wild went back through historical records to investigate further, they found that things didn't add up.

The original report in Nature stated that the electrical disturbance occurred at 10:05pm local time on Oct. 18, 1841. However, Wild's team found that particular train line didn't open until 1846.

So, they delved deeper into the history books to figure out the truth.

"Our research has a hint of a detective story — piecing together a wide range of archived records to better understand a historically severe space-weather event," said team-member Mike Hapgood, a space weather expert at RAL Space, which is the UK's National Space Laboratory, in Oxfordshire.

Combining data from railway timetables, old newspapers, plus historic reports of solar observations and the northern lights and digitized geomagnetic data, Wild and Hapgood's team were able to conclude that the most likely date for the train delay was Oct. 18, 1848, which coincided with a strong solar storm that hit Earth.

This revised date knocks it off top spot in the chronological list of such events. The first recorded disruption to electrical technologies is now a disturbance on the Midland railway network, which had lines covering much of the U.K., in March 1847.

"Although this means it is not the earliest recorded space weather impact, it remains one of the first clear examples of solar activity disrupting critical infrastructure," Wild said. "It also demonstrates the value of combining scientific records with contemporary newspaper reports and archival documents when reconstructing historic space weather events."

The case reminds us that space weather has been a hazard to technology and modern systems for a long time, and isn't just a recent problem.

"Society has been experiencing the effects of space weather on technology for almost as long as electrical technologies have existed," said Wild.

The most dramatic example is the aforementioned Carrington event of 1859, representing the most significant solar storm on record as it caused telegraph poles to spark and battery power supplies to be disrupted. By this point, telegraph operators had grown used to electrical disturbances associated with auroral activity, but even the Carrington storm shocked them — quite literally in some cases, as extra current ran down the telegraph lines — with its ferocity. Should a similar event occur today, it would cause huge black outs, knock out power grids, disrupt communications and fry satellites.

"While today's space weather [monitoring] capabilities are far more advanced than anything available in the 1800s, the modern technologies we depend on are also much more vulnerable to solar storms," said Hapgood.

The current solar cycle 25 peaked in Oct. 2024 and we are just beginning to come out of an extended period of maximum activity. However, it remains to be seen how the rest of this cycle will play out before reaching solar minimum in about 2030. We've already seen severe geomagnetic storms caused by space weather in May 2024 — will we experience another powerful storm before the decade is out?

Our star and primary energy source that makes life on this planet possible may also be a cosmic cannibal. That's according to new research that suggests the sun may have swallowed a super-Earth planet billions of years ago in its early history. And our star may still be hiding the evidence.

The scientists behind this research think that the fingerprints of this violent consumption of a planet may still exist within the solar interior. Super-Earths are common occupants of other planetary systems, and these findings can explain why the solar system lacks such a world.

"Our new study suggests that a planet several times more massive than Earth may have fallen into the young sun and left a lasting chemical imprint deep inside it," Mutlu Yildiz, of Ege University, Turkey, said in a statement.

Yildiz and colleagues theorize that the sun's act of planetary infanticide may help to explain differences between observations of the sun and what is predicted by models of stellar evolution. This includes the depth of the sun's convection zone and the so-called sound-speed structure just below the convection zone.

It could also explain why the surface of the sun is depleted of the element lithium.

"By modelling the sun's evolution and comparing the results with precise observations of its interior, we find that the ingestion of a super-Earth could help explain long-standing differences between standard solar models and observations, including subtle changes in the sun's internal structure and its depleted lithium abundance," Yildiz said. "We were interested in whether these problems might have a common origin in the early chemical history of the sun."

The researcher explained that young stars like the sun during its infancy are surrounded by vast flattened clouds of gas and dust called protoplanetary discs, where substantial amounts of material can move between the disc and the star.

"Since planets are made of material that is chemically different from the gas in the disc, we wondered whether the early engulfment of a planet could have left a chemical signature inside the young sun," Yildiz said.

What happened to the sun's planetary meal?

Using advanced stellar evolution software, Yildiz and colleagues tested their idea by investigating different ways the sun could have swallowed a planet.

Their results found the best fit for the sun's current characteristics was the cannibalism of a planet between five and ten times the mass of the Earth, a type of planet called a super-Earth. This could explain the strange, unpredicted characteristics of the sun.

We thought planetary engulfment might affect the solar structure but did not expect the calculations to converge on such a specific super-Earth mass range," said Professor Yildiz. "That was one of the most interesting outcomes of the study."

The team's research is supported by previous studies that suggests one or more super-Earth planets could have formed with the orbit of Mercury, the closest planet to the sun.

These worlds would have then migrated through the protoplanetary disk surrounding the infant sun before crashing into the star.

But this new study leaves open the possibility that something else, other than this violent collision with the sun, may explain the discrepancies in measurements of the sun's interior and its lithium content. The team's model doesn't need a planet to have been totally engulfed by the sun.

Currently, this idea is based on computer modelling and unexplained solar features, but the researchers think that the predicted structural and chemical signature of a planetary engulfment could still exist within our star and could be detected.

"The earlier work proposed that a super-Earth could have formed and migrated into the young sun. Our paper asks whether the sun itself could still carry observable evidence that such an engulfment actually happened, and we believe it could," Yildiz concluded. "The next step is to see if these fingerprints can be independently detected."

The research was published on Thurs (Sept. 10) in the journal Monthly Notices of the Royal Astronomical Society.

New research suggests that dust from meteorites contains a "fossil record" dating back to the formation of the sun. The research reveals that magnetism played a far greater role in the birth of the solar system than had previously been suspected.

Around 4.6 billion years ago, the solar system was a cloud of gas and dust, known as a solar nebula. Over the next few million years, this cloud began to flatten, forming a donut-shaped ring or torus with a budding star gathering mass at its core. Eventually, planets would form within this so-called protoplanetary disk.

Scientists have always theorized that gravity was the main sculptor during this early era. But the new study suggests that gravity had major assistance from magnetism. The signature of this additional cosmic artist was found within grains of dust sealed in DOM 08006, a meteorite recovered from Antarctica in 2008.

The grains found by the team are calcium-aluminum-rich inclusions (CAIs), which are thought to have formed during the first 200,000 years of the solar system. That potentially makes them the oldest samples of solar system material ever seen.

"We know they are the oldest things we have of the early solar system," team leader Cauê Borlina of Purdue University said in a statement. "But CAIs are very complex and are not all the same, even within a 1-millimeter piece of the meteorite. So we have to carefully identify what types they are."

These CAIs indicated that there was a magnetic field in the proto-solar system even during its solar nebula phase. This magnetic field would have been stronger than Earth's magnetosphere and, as such, would have influenced the flattening of the solar nebula.

"This transition, from a spherical cloud to a protoplanetary disk, is one of the most significant events in all of solar system history," team member Benjamin Weiss, of the Massachusetts Institute of Technology (MIT), said in the same statement. "It has long been theorized that gravity caused this, but our measurements show magnetism likely played a role."

A new spin on early solar system magnetism

In the newly forming solar system, a magnetic field would have been generated when charged particles were sent spinning through the collapsing cloud of gas and dust that birthed the sun. This plasma would then have sustained that field.

As such, that magnetism must have affected the material in the solar nebula that would become the solar system. For that reason, the team reasoned that the strength of this field should be "locked in" to materials from the time as remanent magnetization. This matter could make its way to Earth in meteorites.

In fact, the same scientists who conducted this research previously found evidence of a magnetic field that existed 2 million years into the formation of the solar system, baked into meteorites. That's an impressive and important find, because this magnetic field would have helped planets like Earth form — but the sun was already around by that point. Thus, the team was after an earlier magnetic field, one that predated our star.

"Nowadays, people don’t debate whether magnetism is present when planets are forming. But the debate is around the very early solar system, before planets are forming, when there’s just a disk," Borlina said. "That's where the debate still resides, and that’s where we’re operating now."

DOM 08006 is one of the most unspoiled or "primitive" meteorites ever discovered, retaining and preserving materials, including CAIs, as they were when the sun was forming.

"Other meteorites went through many different processes over this 4.5 billion-year history," said Weiss. "They were formed in the solar nebula, then added to bodies with water, then got destroyed, moved to the asteroid belt, and then landed here. But somehow, DOM has experienced less alteration than any other meteorite."

If a magnetic field existed during the earliest stage of the solar system, it should be observable in the matter that makes up DOM 08006.

The team was able to isolate and identify a handful of CAIs that contained inherently magnetic minerals such as iron, which they tested to measure any magnetism they had retained.

Studying these grains, the researchers found evidence of a magnetic field 12 times stronger than that of Earth. They think this magnetic field may have played a crucial role in the evolution of the solar system.

"We think these kinds of magnetic fields were helping to move gas from the protoplanetary disk inward toward this central star, the sun,” Borlina said. "Gravity is also playing a role. But we are now showing that, if you want to fully understand how the sun and planets formed, you should include magnetic fields in the ingredients that make them."

The new study was published Aug. 7 in the journal Proceedings of the National Academy of Sciences.

A spectacular series of glowing plasma loops arcs above the sun in this remarkable view captured from an astrophotographer's backyard.

What is it?

This image is a still from a high-resolution timelapse captured by astrophotographer Mark Johnston from Scottsdale, Arizona on Aug. 21, 2026.

The footage shows a coronal loop arcade — a series of arching loops of hot plasma shaped by the sun's magnetic field — extending high above the solar limb, or apparent edge of the sun.

Johnston recorded the scene for more than two hours, from 7:56 a.m. to 10:12 a.m. local time. His footage reveals the movement of plasma within the loops, including 'coronal rain' as material cools and falls back towards the lower solar atmosphere along magnetic field lines.

The sequence was captured using a TEC160FL refractor equipped with specialized hydrogen-alpha (H-alpha) solar imaging equipment, which helps reveal structures in the sun's atmosphere that would otherwise be very difficult to see.

Why is it incredible?

Coronal loop arcades like this one are a rare sight, but Johnston was particularly lucky to catch this one almost side-on at the edge of the sun, revealing the dramatic arching shape in exquisite detail.

"To see one AND catch it right on the limb AND have it happen on a clear day when I'm home and able to catch it was a real treat," Johnston told Space.com in an email.

Lucky for us, Johnston keeps a close eye on our star. The first thing he does each morning is check real-time imagery from NASA's Solar Dynamics Observatory (SDO) to see what the sun is up to.

"One day I saw this and leapt out of bed and dashed to get set up to capture it," Johnston said.

And this isn't the first spectacular solar show Johnston has captured from his backyard. Back in June, he imaged a colossal 'Godzilla' plasma cloud seemingly stalking the edge of the sun, complete with streams of coronal rains cascading back towards the solar surface.

Aurora chasers are on alert after NOAA's Space Weather Prediction Center (SWPC) issued a moderate (G2) geomagnetic storm watch for Friday (Aug. 28), as coronal mass ejections (CMEs) launched from the sun yesterday (Aug. 25) head toward Earth.

The CME arrival follows a powerful M6.9 solar flare from restless sunspot region 4513 on Aug. 25. NOAA's SWPC has also issued a minor (G1) geomagnetic storm watch for Thursday (Aug. 27), as a stream of fast solar wind from a coronal hole is expected to buffet Earth ahead of the incoming CMEs

The M6.98 solar flare erupted from the active sunspot region 4513 and peaked at 6 a.m. EDT (1000 GMT), according to SpaceWeatherLive. 4513 has been particularly active over the previous 24 hours, firing off a barrage of solar flares including five powerful M-class eruptions. Solar flares are ranked by strength into five classes — A, B, C, M and X — with each class 10 times more powerful than the one before it. M-class flares are the second-strongest category, sitting just below the most powerful X-class eruptions.

The eruption also triggered a moderate (R2) radio blackout across the sunlit side of Earth, affecting high-frequency radio communications over parts of Africa, Europe and the Arctic.

CME incoming and possible northern lights?

The M6.9 flare wasn't the only eruption to launch material into space on Aug. 25. Several CMEs left the sun that day and NOAA's SWPC now anticipates their arrival at Earth.

NOAA's SWPC has issued a moderate (G2) geomagnetic storm watch for Aug. 28.

Before then, a coronal hole high-speed stream is forecast to reach Earth, prompting a minor (G1) geomagnetic storm watch for Aug. 27. NOAA forecasts isolated G1 to G2 conditions across Aug. 27-28 due to the combined influence of the high-speed solar wind stream and the incoming CME activity.

During G2 geomagnetic storm conditions, the northern lights can push farther south than usual, potentially becoming visible across parts of the northern U.S. and northern Europe.

If the glancing CME arrival coincides with the high-speed solar wind stream, the two influences could work together to ramp up geomagnetic activity and potentially enhance aurora activity.

How much of an impact the CME ultimately has will depend on its exact arrival time and, crucially, the orientation of its magnetic field when it reaches Earth. A strong southward magnetic field would interact more effectively with Earth's magnetic field, increasing the chances of stronger geomagnetic activity.

We'll be keeping a close eye on the latest models and space weather forecasts as Friday approaches and will update this story as more information becomes available.

Editor's note: This story was updated on Aug. 26 at 4:00 a.m. EDT (0800 GMT) to include NOAA's latest forecast and geomagnetic storm watches for Aug. 27 and Aug. 28.

On Aug. 25, 1997, NASA launched the Advanced Composition Explorer, or ACE satellite to study energetic particles traveling through space.

It lifted off from Kennedy Space Center in Florida on a Delta II rocket and spent the next three and a half months making its way to its orbital post near the L1 Lagrangian point, a point of gravitational equilibrium between Earth and the sun. There, the spacecraft is monitoring the stream of accelerated particles coming from the sun known as the solar wind.

ACE provides 24/7 continuous coverage of the solar wind, which lets scientists know when to expect geomagnetic storms that can disrupt communication satellites and power grids on Earth.

Why it mattered

The ACE satellite is a NASA sentinel survivor.

When it launched in 1997, NASA hoped the ACE satellite mission would last up to five years as it monitored solar wind speeds and conditions, as well as the flow of other critical charged particles through space, such as galactic cosmic rays, as well as interplanetary and interstellar particles.

As of today, ACE has been hard at work for 29 years and shows no signs of stopping. It's one of NASA's oldest still-operating sun-monitoring spacecraft (the Solar and Heliospheric Observatory, or SOHO, is two years older, as it launched in 1995).

ACE serves as a core part of NASA's early-warning system for incoming space weather. It's nine primary instruments were between 10 and 10,000 times better than any sensors flown in space when the satellite launched in 1997. In 2005, one of those instruments — the Solar Energetic Particle Ionic Charge Analyzer — stopped sending data, but it is the only instrument to be lost during ACE's lifetime, NASA has said.

A misbehaving coronal mass ejection (CME) that blew out a hidden cloud of charged particles aimed at Earth has been tracked by a record 17 spacecraft spread throughout the solar system, revealing the CME to be surprisingly lopsided.

CMEs are "burps" from the sun – huge clouds of magnetized plasma belched out from the sun's hot outer atmosphere, the corona, by the energy resulting from a solar flare. The magnetized CME cloud then expands out into the solar system, and the charged particles that the cloud contains are a significant radiation hazard to astronauts, spacecraft and even passengers on jet liners, but they also have a beautiful side as they can trigger the beautiful lights of the aurora when they intercept Earth.

CMEs occur on a regular basis, but one that erupted from the sun at 00:48 UT (7:48 p.m. ET) on Dec. 15, 2024 proved to be rather special.

"We used observations from 17 spacecraft to track and characterize this CME," Adrienn Luspay-Kuti of Johns Hopkins University Applied Physics Laboratory, who led the research that drew all the observations together, told Space.com. "This was a record number of spacecraft for tracking and characterizing a single CME, and gave us an exceptionally detailed view of how the CME evolved."

The previous record had been 10 spacecraft, but they had mostly been in a rough line from the sun through to the Earth and beyond, meaning that their measurements were somewhat one-dimensional. This time, for the December 2024 CME, the spacecraft were spread far and wide, not just at different distances from the sun, but also substantially wide of the Earth–sun line.

They revealed that the CME had two asymmetric lobes, one moving faster than the other. One of those lobes, which headed for Earth and Mars, would have gone unseen, obscured by the larger but slower lobe that left the sun at a tangent, were it not for the wide spread of the spacecraft.

"Our observations showed a fast lobe propagating through the Earth–Mars sector and a much slower lobe farther west toward STEREO-A," said Luspay-Kuti. STEREO-A is one half of NASA's two-spacecraft space weather monitoring system known as the Solar Terrestrial Relations Observatory.

The onset of the CME was seen by the joint NASA–ESA Solar and Heliospheric Observer (SOHO), which has been constantly monitoring the sun for more than 30 years. Yet it only saw the slower lobe that erupted at an angle to Earth; the faster lobe heading for our planet was missed, obscured by the slower, larger lobe.

The CME was next detected at a distance from the sun of 0.35 astronomical units (AU; 1 AU is the distance of Earth from the sun) on Dec. 16 moving through space near Mercury and the European Space Agency's BepiColombo mission (which finally arrives into orbit around the innermost planet in November 2026).

The next detection, on Dec. 17, was of the "hidden" component arriving at Earth, where a multitude of spacecraft picked it up. The CME was not strong enough to produce significant aurorae. Intriguingly Europe's Solar Orbiter mission, on an elongated orbit around the sun and at the time 0.94 AU from the sun and just 10 degrees off the Earth–sun line, did not detect the CME. This non-detection was actually vital since it helped to constrain the shape of the CME.

Then on Dec. 18, the slower moving lobe reached NASA's STEREO-A spacecraft, which orbits the sun at the same distance as Earth — 1 AU —- but substantially ahead of Earth in its orbit. The lobe that intersected the Earth had an average velocity of 522 miles (840 kilometers) per second, but the other lobe dragged its feet, moving at an average of 332 miles (534 km) per second from the sun and past BepiColombo and STEREO-A. In fact, by the time it reached STEREO-A, it had slowed to about 248.5 miles (400 km) per second. Both lobes decelerated as a result of friction with the regular solar wind that the CME was overtaking, and the range of velocities measured in the CME told researchers that the solar eruption was not traveling as a single, unified front.

Beyond Earth NASA's Europa Clipper mission, on which Luspay-Kuti is the Principal Investigator for the spacecraft's Plasma Instrument for Magnetic Sounding (PIMS) experiment, detected the faster moving lobe at 1.19 AU as the spacecraft was cruising to Mars for a gravity assist to help it on its journey to Jupiter. At the red planet, the now-defunct MAVEN mission also detected the CME on Dec. 19 to Dec. 20.

To have not only so many spacecraft follow the progress of a CME but also enough spacecraft off the Earth–sun line to measure the shape of the CME, at least in two dimensions, is a significant step forward in understanding and forecasting the propagation of CMEs.

"This matters for future human exploration because a missed CME can mean losing valuable warning time," said Luspay-Kuti. "Fast CMEs can drive shocks that accelerate high-energy particles, which can pose a radiation hazard to astronauts outside Earth's protective magnetic field. This is why observations from multiple viewpoints, including spacecraft away from the sun–Earth line and planetary missions operating during their cruise phase, will become increasingly important for space-weather forecasting as human exploration moves further from Earth."

The asymmetrical double-lobed structure of this particular CME was certainly a surprise. The cause of the asymmetry remains unclear at present, though Luspay-Kuti told Space.com that researchers are investigating. The main question is, how frequent are asymmetric CMEs?

"In the context of previous observations, this event is at the most extreme end of observed CME variability," said Luspay-Kuti. "Are highly asymmetric CMEs actually fairly common but we fail to recognize them because we don't have enough observational coverage, or are they genuinely rare?"

The 17 spacecraft that detected or imaged the CME across some or all of its various stages – the bow shock and turbulent sheath ahead of the magnetic cloud, the CME itself and the turbulent wake left in the solar wind after its passing – were the following: SOHO (initial imaging), BepiColombo, NASA's Solar Dynamics Observatory, STEREO-A, the four spacecraft of the Magnetospheric Multiscale (MMS) mission, the two spacecraft of the ARTEMIS (Acceleration, Reconnection, Turbulence, and Electrodynamics of the Moon's Interaction with the sun) mission, NASA's Wind, ACE (Advanced Composition Explorer), GOES (Geostationary Operational Environmental Satellite) and DSCOVR (Deep Space Climate Observatory) missions, Europa Clipper, MAVEN and Solar Orbiter, the latter of which made measurements but did not detect the CME.

In the future, these missions will be joined by the European Space Agency's Vigil mission that will watch for space weather when it launches in 2031 for the sun–Earth L5 Lagrange point, 60 degrees behind Earth in its orbit and therefore providing additional off-axis monitoring.

The findings were published on Aug. 19 in the journal Science Advances.

We're just one week away from a stunning partial lunar eclipse on Aug. 27-28, when billions across North America, South America, Africa and Europe will see Earth's shadow dye the moon a subtle crimson hue, while leaving a thin crescent exposed to direct sunlight.

August's partial lunar eclipse will occur as Earth passes directly between the sun and moon during the full moon phase — an imperfect alignment that will see our planet's intense inner shadow cover 96% of the visible face of our natural satellite.

Stargazers on the night side of Earth will catch their first glimpse of our planet's umbra (the darkest, innermost part of its shadow) creeping onto the moon's surface at 10:33 p.m. EDT on Aug. 27 (0233 GMT on Aug. 28), according to TimeandDate.com. The vast shadow will continue its advance across the crater-scarred landscape in the hours that follow, until it hits the point of maximum eclipse at 12:12 a.m. EDT on Aug. 28 (0412 GMT).

Around this time, you may notice the shadowed region of the moon take on a reddish-orange color, as sunlight filtered through Earth's atmosphere is bent onto the lunar surface — a phenomenon often referred to as a "Blood Moon" during a total eclipse.

Each phase of a lunar eclipse occurs simultaneously for everyone viewing from the night side of Earth, where the lunar disk is visible. However, local timings will differ significantly depending on your location on Earth.

If you're watching from a city on the West Coast of the United States like California, then the point of maximum eclipse will occur shortly after midnight local time on the night of Aug. 27-28.

Viewers in the United Kingdom, meanwhile, won't observe the moment of maximum eclipse until shortly before sunrise on Aug. 28, as the moon lurks low on the southwestern horizon. Be sure to check out a trusted website like TimeandDate for eclipse timings specific to your location.

You won't need any special kit to protect your eyes during a lunar eclipse as you would during a solar eclipse, when there is a serious risk of vision damage from looking directly upon the sun. However, a pair of quality binoculars or a telescope will give you a stunning view of Earth's shadow as it races across the lunar disk.

Need to upgrade your equipment? Then be sure to read our roundups of the best binoculars and telescopes available in 2026. You should also check out our guide to photographing a lunar eclipse, along with our picks of the top cameras and lenses for astrophotography.

The Aug. 12 total solar eclipse didn't only plunge millions of people across Greenland, Iceland and Spain into a false twilight — a fleet of spacecraft orbiting our planet managed to capture the magic, too.

August's total solar eclipse occurred as the moon passed directly between the sun and Earth during its monthly new moon phase. Those lucky enough to be in the path of totality watched on in awe as the moon progressively swallowed the light of the sun, ultimately revealing our star's tenuous atmosphere against a prematurely darkened evening sky.

It was a show of truly epic proportions — and maybe one whose scale can be particularly appreciated when viewed through the mechanical eyes of NASA and European Space Agency (ESA) spacecraft that observe our planet and sun from afar. Read on to see some breathtaking views of the Aug. 12 total solar eclipse from orbit.

The Aug. 12 total solar eclipse, seen from space

Our first view comes courtesy of NASA astronaut Jessica Meir, who captured the moon taking a bite out of the sun from the Russian segment of the International Space Station (ISS) on Aug. 12.

"Given the location of the @Space_Station at the time of the total solar eclipse today, we saw only a partial eclipse, with a peak of around 18% sun coverage," Meir said in an X post accompanying the photographs.

Around the same time, photographer Joel Kowsky managed to line up a beautiful shot of the ISS as it passed across the face of our eclipsed star in the skies over Hodgdon, Maine.

The dual spacecraft of the European Space Agency's Proba-3 mission also captured a lovely (though largely redundant) view of the moon moving to occult the sun's disk, which, in this case, was already perfectly hidden behind the lead spacecraft's coronograph!

Both Proba-3 spacecraft are designed to fly in perfect formation in line with the sun. The "Occulter" spacecraft, closest to the sun, is equipped with a large sunshield, or coronagraph. This coronagraph blocks the sun's disk for the more distant member in the Proba-3 formation, allowing that spacecraft to image our star's atmosphere in incredible detail.

Thanks to their unique setup, for a brief moment on Aug. 12, the Proba-3 spacecraft recorded a rare double eclipse, as the moon and its artificial mimic simultaneously hid light emanating from our parent star.

Sitting about 22,370 miles (36,000 kilometers) above Earth's surface, ESA's Meteosat Third Generation Imager Satellite (MGT-I1) caught a spectacular view of the moon's shadow darkening our planet.

The moon's shadow can be seen arcing south in the satellite imagery, before eventually combining with the advancing terminator line, which heralded the transition from day to night wherever it passed.

That same shadow was observed on Aug. 12 by the U.S. National Oceanic and Atmospheric Administration's GOES-19 satellite as it kept watch over Earth from its perch in geostationary orbit.

Astronomers have watched a dead star, in the guise of the Helix Nebula, being recycled back into the interstellar gas from which it originally came, bringing the story of that star full circle.

Stars can last for millions, or even billions, of years, but they do not last forever. When a sun-like star reaches the end, it blossoms into a beautiful planetary nebula. The Helix Nebula, located 650 light-years away in the constellation of Aquarius, the Water Bearer, is one such example of a planetary nebula.

The Helix's central star has run out of hydrogen needed for nuclear fusion reactions in its core. This caused the core to begin to contract and raised the temperature in the star's outer layers, which ignited fusion reactions there instead. This had the effect of causing the star to bloat into a red giant. Then, eventually, the outer layers of that red giant detached and expanded into space to form the Helix Nebula. Meanwhile, the star's inert core contracted and became a white dwarf.

As the nebula expands, it gradually disperses into the interstellar medium (ISM), feeding the elements formed within the star back into interstellar gas clouds. These clouds will eventually produce the next generation of stars. However, astronomers had never actually seen the point at which a dead star's remains are absorbed into the ISM — until now.

"We are seeing material shed near the end of a star's life being broken apart and returned to the galaxy," said Yale University's Pieter van Dokkum, who led the study, in a statement. "That hand-off — from recognizable stellar debris to the diffuse gas between the stars — has been very difficult to observe."

Van Dokkum's team were not actually looking for this. Instead, they were conducting routine calibration of a new astronomical instrument called MOTHRA, the Modular Optical Telephoto Hyperspectral Robotic Array at the El Sauce Observatory in Chile. When complete, MOTHRA will be armed with 1,140 telephoto lenses that will scrutinize the night sky while looking for traces of faint gas in the Milky Way galaxy.

Astronomical instruments require calibration before use, and this is accomplished by targeting a familiar object in the sky and tuning the instruments to how that object should appear. The MOTHRA team used the Helix Nebula to calibrate the telephoto lenses that they currently have operational, and that was when they found something unexpected.

"We thought we were taking a calibration image of one of the best-known nebulas in the sky," Roberto Abraham of the University of Toronto said in the statement. "Instead, we found this extraordinary network of bow-shaped structures. It was immediately clear that the faint outer Helix was telling us a story that had largely been missed."

The Helix Nebula appears donut-shaped and has been imaged countless times before by both professional observatories such as the Hubble Space Telescope and James Webb Space Telescope, and by amateur astronomers whose long exposures can reveal an outer halo of gas around the nebula's bright ring. To give an idea of scale, the outer edge of the bright ring is 5.7 light-years across, and the outer halo exists beyond even this.

The team discovered 22 complete or partial arc-shaped clumps of gas in the outer halo. They are called bow shocks and they arise from the motion of something pressing into another medium, in this case clumps of gas that have expanded out from the planetary nebula running into and plowing through the ISM. It is similar to the bow-shaped waves that ride ahead of the prow of a boat in water.

"The shocks change dramatically with distance from the central star," Imad Pasha of Dragonfly Focused Research Organisation, said in the statement.. "Those nearer the center are large, thin and sharply defined. Further out, they become smaller, fuzzier and increasingly fragmented."

This implies a progression, and that the deeper into the ISM the clumps of the star's ejected material press, the more they become eroded and dispersed back into the interstellar gas. The team estimate that material from the planetary nebula can survive for about 10,000 years after encountering the ISM before they are completely shredded and absorbed back into it.

Stars are born from the molecular gas clouds that lie in interstellar space, and these clouds are enriched with the elements produced by fusion reactions within previous generations of stars. Now, thanks to MOTHRA's observations of the Helix Nebula, we have seen these elements being gifted to the Milky Way at large, and in millions or billions of years they will contribute to a new generation of stars, planets and possibly life.

Our own solar system, and Earth along with it, were formed 4.6 billion years ago from elements produced by dead stars. In another five billion years' time, our sun will also exhaust its supply of hydrogen and its fusion reactions will cease, causing it to unfurl into its own planetary nebula.

"Far in the future the sun will go through a similar process and its material will enter the same cycle," says van Dokkum.

All the elements and molecules that make up you and everything around you will be given back to the Milky Way, and one day it will be reborn again and begin the story of a new star system. What will that story bring, we wonder?

The findings from the Helix Nebula were published on Aug. 12 in the journal Nature.

And just like that, it's over.

Total solar eclipses are incredible moments in time, but they are fleeting. As the moon passes directly in front of the sun and its shadow sweeps across Earth's surface, the temperature drops and the light takes on an eerie twilight quality. Birds and other animals go quiet. It's a spectacle unlike any other. And for millions today who were lucky enough to be in the path of totality across Greenland, Iceland and Spain, that's exactly what they experienced.

"I cannot believe what I just witnessed. I knew what to expect  — I've seen thousands of photos but nothing compares to that feeling you get when you watch the sun transform before your very eyes," Space.com skywatching editor Daisy Dobrijevic said after watching the eclipse from the deck of the MS Spitsbergen on the HX Expeditions eclipse voyage in Scoresby Sund, Greenland on Aug. 12, 2026.

"It looked so big in the sky with the delicate corona streaming out into the abyss. Jupiter, Mercury and Venus even joined in the show. The huge prominence was the icing on the cake," Dobrijevic added.

"This is something I will never forget and I feel privileged to have experienced it in one of the most remarkable environments on Earth and alongside an incredible group of people aboard HX Expedition's MS Spitsbergen."

The 182 mile-wide (293-kilometer) path of totality — the line "drawn" on the face our our planet by the moon's shadow — began near Siberia over the Arctic Ocean and first arced down into eastern Greenland.

From there, the path stretched across western Iceland and then into northern Spain where millions gathered to witness the spectacle.

"It was the most incredible thing I've seen in my entire life," said Space.com skywatching writer Anthony Wood after witnessing the eclipse from Valoria la Buena, Spain alongside a team of citizen scientists from the Dynamic Eclipse Broadcast initiative. "It feels like it really shouldn't be happening. It strikes the lizard part of your brain that just tells you that this shouldn't be real."

The path then crossed the Balearic Islands just east of Spain before ending over the Mediterranean Sea as the sun set.

Eclipse-watchers inside the narrow path of the moon's shadow were given a rare naked-eye glimpse of the sun's outer atmosphere, known as the corona. Witnessing the crown-like shape of the corona stretching away from the dark shadow of the moon is one of the most breathtaking moments of an eclipse. Photographs don't do it justice, as they rarely do.

Outside of the path of totality, skywatchers throughout Europe and Scandinavia were able to catch a glimpse of a partial solar eclipse — in which the moon appears to take a "bite" out of the sun.

Space.com's Harry Bennett captured the partial eclipse from a hilltop in Somerset, England, shooting the scene with a Unistellar Equinox 2 smart telescope equipped with a solar filter.

The partial solar eclipse was also visible for much of the northeastern United States and as far west as Michigan. Much of Canada got to witness the partial eclipse too, and so did Alaska.

What causes a total solar eclipse?

A total solar eclipse happens when the moon passes directly in front of the sun as seen from Earth. When this alignment happens, the moon casts its shadow along a line known as the path of totality. Only within this stripe will you be able to experience full totality.

Another factor to consider is that the moon has an elliptical, or oval-shaped, orbit. This means that it's sometimes closer to Earth than other times. Total solar eclipses only occur when the moon is at just the right distance from Earth, making it appear the same size in the sky as the sun (or even slightly larger). This obscures the blinding light of the sun, allowing viewers to glimpse our star's outer atmosphere, or corona.

When the moon is a bit farther away from Earth, it appears relatively smaller. And when solar eclipses fall on a date when the moon is at this greater distance from our planet, the moon doesn't completely block the sun. This creates what's known as an annular solar eclipse, or a "ring of fire" in the sky.

When is the next total solar eclipse?

The next total solar eclipse will occur on Aug. 2, 2027 and will be visible throughout a 160-mile-wide (258-kilometer) path that crosses southern Spain, northern Morocco, northern Algeria, northern Tunisia, northeast Libya, central Egypt, the northeastern tip of Sudan, southwest Saudi Arabia, Yemen and the northeastern tip of Somalia.

Outside of this path, a partial solar eclipse will be visible to most of Europe, much of the African continent, the Middle East, Southeast Asia, eastern Canada and parts of Maine.

In North America, the next total solar eclipse will take place on March 30, 2033, and will be visible from Alaska. Looking farther out, the U.S. states of Montana, South Dakota, North Dakota, and areas of Canada will witness a total solar eclipse on Aug. 23, 2044.

The first breathtaking photos of totality for the total solar eclipse 2026 are pouring in, revealing incredible views of the sun's atmosphere radiating out from behind the moon's colossal silhouette.

Eclipse chasers have spent the past few hours watching in awe, as the moon transformed the sun into an incandescent crescent in the run up to totality, before swallowing it entirely in the skies over Scoresby Sund, Greenland as seen from the deck of the MS Spitsbergen on the HX Expeditions eclipse voyage.

Read on to see spectacular photos of the sun's corona glowing in the false twilight of totality. And be sure to stay with us in the coming hours as the moon's central shadow sweeps over Europe, before ultimately disappearing from view off the north coast of Africa at 2:34 p.m. EDT (1834 GMT).

First photos of totality

The first photos of totality revealed the sun's corona, visible thanks to the moon blocking most of our star's light.

Luckily, weather cooperated for the eclipse chasers on the MS Spitsbergen on the HX Expeditions eclipse voyage in Scoresby Sund, Greenland.

Space.com's own skywatching editor Daisy Dobrijevic was onboard, capturing the first images of totality.

As the moon drifted past the sun, the first glimpses of the sun began to reveal themselves as the path of totality moved onwards towards Spain.

We'll have more coverage on our total solar eclipse live blog throughout the day, including reports from Skywatching Editor Daisy Dobrijevic as she catches the entirety of the eclipse unfolding in the skies over Greenland aboard an HX Expeditions cruise ship.

Skywatching Writer Anthony Wood will also be giving you the live updates from his vantage point in central Spain, where the eclipsed sun will set below the horizon just a few short hours from now.

Today (Aug. 12), millions of people across Greenland, Iceland and Spain will witness a total solar eclipse as the moon completely covers the sun, turning day into night, albeit briefly.

It's Europe's first total solar eclipse since 1999, and with a maximum of 2 minutes, 18 seconds of totality, it will be worth the wait … weather permitting!

Even if you're not inside the path of totality, there's still plenty to see. A dramatic partial solar eclipse will be visible across much of Europe, offering millions more the chance to watch the moon take a 'bite' out of the sun. More than 90% of the sun will be covered for major cities such as London, Paris and Dublin.

Where will the eclipse be visible?

Today's eclipse will unfold over roughly 96 minutes as the moon's shadow races across Greenland, Iceland and Spain. Totality begins in Greenland in the late afternoon before reaching Spain in the evening, where skywatchers will witness the rare spectacle of a low-horizon sunset eclipse.

How to observe the eclipse

Never look directly at the sun without proper eye protection.

During the partial phases of the eclipse, you must use solar eclipse glasses or a certified solar filter. Looking at the sun without appropriate protection can cause serious and permanent eye damage.

The only time it is safe to view the eclipse without eye protection is during the brief period of totality, when the moon completely covers the sun. As soon as even a small portion of the sun reappears, eclipse glasses must be worn again.

For more information, check out our guide to observing the sun safely. If you haven't been able to get hold of some solar eclipse glasses, don't fear! We also have a handy guide on how to safely view the eclipse using items from around the home.

A total solar eclipse isn't just a spectacular sight to witness for those lucky enough to lie in the path of totality (or travel to it, as many dedicated skywatchers do). It also gives scientists a rare chance to study the sun's outer atmosphere, or corona, during the day.

As such, NASA plans to take full advantage of the opportunity for the upcoming total solar eclipse happening on Aug 12.

The space agency's WB-57 high-altitude research jet will chase the moon's shadow across the globe, which will extend the agency's ability to capture data from the eclipse. The NASA-supported Nationwide Eclipse Ballooning Project will also coordinate teams to release balloons that will help us know how our atmosphere changes when an eclipse turns the sky dark during the day.

"From our unique perspective on Earth during a total solar eclipse, scientists can study the sun's corona in a way we can't from anywhere else in the solar system," Kelly Korreck, eclipse program manager at NASA Headquarters in Washington, said in an official announcement.

"The sun impacts our daily life, satellites, and astronauts in space, and we can take advantage of this moment to advance our understanding of that influence," she continued.

Inside the research jet's nose cone, four cameras will capture images of the corona's structures, outflows, and changes. This data may help scientists gain a better understanding of how materials within the corona relate to solar winds.

"The sun is always changing," Amir Caspi, principal investigator for the study at Southwest Research Institute in Boulder, Colorado, said in the announcement. "Every eclipse is different. So we could see things we didn't see before. And we learn from each eclipse how to better observe the next one."

Angela Des Jardins at Montana State University will lead the Nationwide Eclipse Ballooning Project, with the help of students from universities in the U.S., Iceland and Spain.

By releasing balloons in anticipation of the eclipse, scientists will be able to look at the ozone levels in the atmosphere during the eclipse and study how the eclipse impacts the "boundary layer" of the Earth, which shifts due to temperature and moisture in the air.

Both the research jet and balloons were used to collect data during the total solar eclipse in April 2024. These new projects will use what NASA learned last time to sharpen up the methods, and hopefully provide new insights into the relationships between the sun, moon, and Earth.

A spectacular total solar eclipse will coincide with the peak of the Perseid meteor shower on Aug. 12-13. But will you be able to spot shooting stars in the false twilight of totality?

Perseids appear as Earth plows through the stream of debris shed by comet Swift-Tuttle. Up to 100 shooting stars may be seen each hour around its peak under ideal dark skies, as particles from the ancient comet collide with our atmosphere at speeds of 133,200 mph (214,365 km/h) to etch a fiery path through the summer night sky.

It's an unmissable highlight of the skywatching calendar, supercharged in 2026 by the spectacle of a total solar eclipse, which will plunge millions across Greenland, Iceland and Spain into the darkness of an eerie twilight, as the moon crosses the face of the sun.

Is it possible to see shooting stars during totality?

Yes. The most brilliant Perseid shooting stars can shine bright enough to be spotted in the brief twilight of totality. But it's all a question of timing.

"It would have to be a fireball that passed through the darkest portion of the sky," Robert Lunsford of the American Meteor Society told Space.com in an email. "The Perseids usually produce about one fireball per three hours at night. That's asking a lot for one of these bright meteors to appear during a 2-3 minute window. If anyone does see one, they had better go play the lottery asap!"

NASA Meteoroid Environments Office head Bill Cooke added his own word of caution, noting that the relatively bright sky during totality will likely hide all but the most brilliant Perseids from sight.

"Only Perseid fireballs will be visible," Cooke told Space.com in an email. "Given the brightness and duration of the eclipse, you might see one if you're extremely, extremely lucky. [The] most likely scenario is that you will see no meteors whatsoever."

The odds are definitely stacked against you. But you never know. A piece of comet Swift-Tuttle could've broken away at just the right time, at just the right point in its orbit to meet a fiery end in Earth's atmosphere, just as the sun slips from view. As for our advice? Keep your eyes locked firmly on the eclipse as it unfolds in the skies above you. There'll be plenty of time for hunting Perseids later.

Scientists have captured the sharpest image ever of our sun's surface. This view has revealed incredible new details about the inner mechanisms driving stellar activity.

What is it?

An international team of researchers using the U.S. National Science Foundation's Inouye Solar Telescope has captured the highest-resolution view of the sun's surface.

In analyzing observations from this telescope, the team, made up of researchers from the National Solar Observatory, the NSF NCR High Altitude Observatory and the German Max Planck Institut für Sonnensystemforschung, discovered strange patterns on the sun's surface. The whirling patterns, they found, are actually evidence of what's called Kelvin-Helmholtz instability (KHI), or instability that happens when there is a change in velocity of fluids.

Why is it incredible?

This image is groundbreaking. Capturing the highest-resolution view of the sun's surface is a massive accomplishment, and in the time-lapse video above, you can even see the fluid dynamics on the surface of the sun in motion.

But this view is much more than a beautiful, high-resolution image. These observations have revealed swirls on the sun's surface at the edges of the magnetic areas, allowing the team to identify KHI on the sun's surface. This fluid instability has long been suspected on the sun, but these observations are the first time they have ever been directly seen like this.

“We believe that the discovery of Kelvin-Helmholtz Instability in the solar photosphere, backed up by analysis of numerical simulations, is a major step forward in our understanding of the dynamics and evolution of solar and stellar plasma, and will serve as a basis for future discoveries," David Boboltz, the deputy director at the National Solar Observatory, said in a statement.

A paper describing these findings was published recently in the journal Nature.

If you're planning to watch the total solar eclipse on Aug. 12, knowing exactly when to look up is crucial.

While totality will be visible from parts of Greenland, Iceland and Spain, millions more people across Europe will experience a dramatic partial solar eclipse. Whether you're chasing the moon's shadow in Reykjavik or watching the moon take a 'bite' out of the sun from London, Paris, or Berlin, timing is everything.

What is a total solar eclipse?

A total solar eclipse occurs when the moon moves directly between Earth and the sun, completely blocking the sun's disk from view.

During totality, the sky darkens significantly, temperatures drop and bright stars and planets can even become visible. Observers can also catch a glimpse of the sun's outer atmosphere, known as the corona, glowing around the silhouetted moon.

Totality — when the sun is completely obscured — is only visible within the narrow path of the moon's shadow. Outside that path, observers may see a partial solar eclipse, whereby only a portion of the sun is covered.

REMEMBER to NEVER look directly at the sun. To view this solar eclipse safely, you must use solar filters. Only during the brief period of totality when the moon completely covers the sun, is it safe to look at the sun without protection. Observers will need to wear solar eclipse glasses, and cameras, telescopes and binoculars must have solar filters placed in front of their lenses at all other times.

Our how to observe the sun safely guide tells you everything you need to know about safe solar observations.

After this, when is the next solar eclipse?

After the total solar eclipse on Aug. 12, 2026, the next solar eclipse will be an annular solar eclipse on Feb. 6, 2027 visible across parts of Africa and South America. The next total solar eclipse will be a spectacular event on Aug. 2, 2027. Visible across North Africa, it will be the longest totality on land since 1991.

We're just a few short days away from the Aug. 12 total solar eclipse, when millions will watch as the moon glides across the face of the sun, hiding its light in a wondrous display of orbital mechanics.

The eclipse will unfold during August's new moon phase, as the lunar disk slips silently between the sun and Earth in the daytime sky. Ordinarily, the subtle tilt in the moon's orbit causes its shadow to pass just below, or above our planet, missing it entirely.

However, on Aug. 12, the moon's orbit will carry it into a near-perfect alignment with the sun and Earth, casting its colossal shadow across a 182-mile-wide corridor known as the path of totality, where viewers will get to see the lunar disk fully hide the sun's disk.

The path of totality for the Aug. 12 eclipse cuts through Spain, Iceland and Greenland. Hundreds of millions more watching from outside of this narrow corridor will also bear witness to a spectacular partial solar eclipse, as the moon passes in front of our parent star, without fully obscuring its surface. Those unable to watch the eclipse in person by dint of geography can also follow along online, with details of the livestream to be released closer to the event.

Read on to discover what will happen during each stage of the Aug. 12 total solar eclipse.

Stage 1: The partial eclipse begins

The partial phase of the eclipse officially begins at the moment of "first contact", when the lunar disk takes its first nibble out of the sun — a subtle transformation that will first become visible in the skies over the U.S. state of Alaska at 11:34 a.m. EDT (1534 GMT) on Aug. 12.

You can check out exactly when the partial eclipse will begin from your location and find out exactly how much of the sun will be hidden by the moon using Time and Date's interactive eclipse tracker.

The hour and a half following first contact will see the moon sink ever farther into the sun's disk for those in the path of totality, transforming it from a burning orb into a magnificent shining crescent.

You may notice the temperature drop noticeably, accompanied by a subtle darkening of the sky in the half hour preceding the climactic phase of totality, as the moon reduces the sun to a thin sickle in the evening sky. Pinpricks of light — such as those that shine through a colander, or the gaps in a leaf — will also appear to mirror the scene above, creating a kaleidoscope of tiny bright crescents.

Remember, staring at the sun for even the briefest of moments can lead to permanent loss of vision, so be sure to read our guide on how to view the sun safely and to wear your eclipse glasses or sunoculars during the entirety of the partial phases of the eclipse. You can read our roundup of the best solar viewing equipment to find out more, along with our tips on how to check the quality and condition of your eclipse glasses.

Stage 2: Second contact

Some of the most spectacular moments of an eclipse occur just before and after totality. First, look out for the "diamond ring" effect, as the last sliver of the sun peeks out from behind the lunar disk to appear as a gorgeous celestial jewel, while the outermost layer of our star's atmosphere, the corona, creates a glowing halo around the moon.

Tear your eyes away from the sun for just a second and you may just catch sight of the moon's shadow advancing on you from the west, before it engulfs your surroundings in a false night.

The final seconds before totality will see bright "Baily's Beads" form dazzling points of light on the moon's edge, where the last shreds of the sun's disk shine through the ravines and valleys that scar the ancient lunar surface.

Stage 3: Totality & maximum eclipse

As the last of the sun's surface slips behind the moon, totality begins. This is the climactic phase of the eclipse, when the moon acts like a natural coronagraph to block the brilliance of the sun's disk, ushering in a false night in which our star's outer atmosphere can be seen leaping out from the lunar silhouette.

Totality will last a maximum of 2 minutes, 18 seconds, during which time it's safe to remove your glasses and look at the sun. Just be sure to put them on again before its fiery disk reemerges from the other side of the lunar disk.

That white halo surrounding Earth's natural satellite is the sun's corona — a jacket of superheated gas that surrounds our parent star. Look out for glowing solar prominences leaping outward through the sun's atmosphere, along with the red line of the chromosphere — the layer of the sun's atmosphere beneath the corona — which appears fleetingly at the beginning and end of totality, according to NASA.

The point of maximum eclipse occurs roughly halfway through totality, when the sun's disk is most hidden by the moon.

Eagle-eyed skywatchers may catch Jupiter and Mercury shining to the lower right of the eclipsed sun in the faux twilight experienced during totality, while Venus will appear as a bright star-like object to its upper left. If you're incredibly lucky, you could even spot one of the brightest shooting stars or fireballs of the Perseid meteor shower, which comes to a peak around the same time as the Aug. 12 total eclipse.

Stage 4:Totality ends

The fourth stage of the eclipse comes as the very edge of the sun's disk emerges from behind the moon, marking the end of totality as Bail's Beads and the diamond ring effect play out in reverse, before giving way to an ever-thickening solar crescent.

Stage 5: The partial eclipse ends.

The waning partial eclipse will come to a global end at 3:57 p.m. EDT (1957 GMT), as the moon's silhouette exits the sun's disk in the skies off the west coast of Africa — a moment known to astronomers as fourth contact.

Space.com is on hand to provide expert coverage and on the ground reporting as the eclipse unfolds. Skywatching Editor Daisy Dobrijevic is undertaking an expedition with HX to observe the total solar eclipse from the waters around Greenland, while Skywatching Writer Anthony Wood heads to Spain in a cowboy hat, to catch the orbital showdown with citizen scientists from NASA's Dynamic Eclipse Broadcast Initiative.

It's hardly a "Great American Eclipse," but on Aug. 12, 2026, some parts of the North American continent will see a partial solar eclipse.

Will it be as impressive as on April 8, 2024, when totality visited Mexico, 15 U.S. states and six provinces in Canada? No, yet in some parts of the U.S. and Canada, astronomers will be out in force to capture a significant chunk of the sun as it is obscured by the new moon.

The spotlight may be on the total solar eclipse in Greenland, Iceland, and Spain, but millions across North America can still see the moon take a bite out of the sun on Aug. 12. The farther northeast you are, the deeper the eclipse. Here's everything you need to know about the partial solar eclipse in North America.

During a partial solar eclipse, it is NEVER safe to look directly at the sun without solar eclipse glasses designed for solar viewing. Read our guide on how to observe the sun safely.

Where to see the partial solar eclipse in the U.S.

Between 7:34 a.m. AKDT and 2:52 p.m. EDT, 20 U.S. states will see something of the partial solar eclipse, though only northeastern states will get a good view. Here's a sample of locations and the time of maximum eclipse. Note that the partial eclipse begins (first contact) and ends (last contact) around 55 minutes before and after the time of maximum eclipse given here.

Where to see the partial solar eclipse in Canada

Between 8:38 a.m. MST and 4:38 p.m. NDT on Aug. 12, every province in Canada will be able to see some kind of partial solar eclipse, but those in the east of the country will see something much more significant. Here's a sample of locations and the time of maximum eclipse. Note that the partial eclipse begins (first contact) and ends (last contact) around 55 minutes before and after the time of maximum eclipse given here.

What to expect

This is a small partial solar eclipse in North America, which occurs at lunchtime. In the east of the continent, it will occur high in the sky — about two-thirds of the way between the horizon and the zenith — in the south-southwest. At maximum eclipse, the partially eclipsed sun with resemble a thick crescent or a smile. It won't get dark — that only happens within the path of totality — nor will daylight be affected.

Those using a telescope to observe or image the partial eclipse (using a solar filter) should also consider that Venus — which will be visible just after sunset — reaches dichotomy on Aug. 12. This is the point in its current apparition as the "Evening Star" that it starts becoming interesting in a telescope. Dichotomy sees it reduce to 50%-lit and gradually become an ever-shrinking crescent.

Perhaps more importantly, the early hours of Aug. 13 see the peak of the annual Perseid meteor shower.

When is the next solar eclipse visible from the US after August 2026?

The next solar eclipse on Aug. 2, 2027, will be seen in Newfoundland, Canada, where a 23% partial eclipse will occur at the province's southwestern tip.

On Jan. 26, 2028, during an annular solar eclipse across northern South America, eastern U.S. states and eastern Canada will see a very small partial solar eclipse shortly after sunrise. Florida will have the best view, with around 15% of the sun blocked.

On Jan. 14, 2029, a large partial solar eclipse will be seen in the morning sky across all of North America — up to 81% in northern Canada and 74% in northwestern U.S. states. On June 12, 2029, a smaller partial solar eclipse will peak at 34% just after sunrise from Nunavut, the Northwest Territories and the northern tips of Alberta and British Columbia.

It will be a magnificent day for England's south coast. From Portsmouth's Historic Dockyard and Brighton's Royal Pavilion to Dorset's Jurassic Coast and Cornwall's Land's End, beaches and cliff tops will be plunged into darkness in the day during the U.K.'s first total solar eclipse for almost 91 years. There is, however, a problem — this scenario won't occur until Sept. 23, 2090.

A total solar eclipse visits a location on Earth on average once every 366 years, and the British are currently in no-man's land. Aug. 12, 2026, is particularly cruel, with a path of totality cruising past the British Isles as it surges across the Atlantic Ocean from Iceland to northern Spain. Eclipse chasers in the U.K. are used to traveling, and travel they will, but those left behind will nevertheless experience a very deep partial solar eclipse peaking at 98% in extreme locations. It will be the U.K.'s most significant partial solar eclipse since March 20, 2015, when another path of totality just missed the U.K. to the north.

Where to see the partial solar eclipse in the U.K.

A deep partial eclipse is a compelling sight, and the widespread nature of this one means millions of Brits can experience it without leaving home.

London, Manchester and Glasgow all experience 91.4% coverage, staggered by only a few minutes. Belfast does slightly better at 93.1%, while Cardiff edges ahead among the U.K's capitals at 93.2%. In practice, these differences are subtle — this is a nationwide event that requires no travel. That said, expect crowds at U.K. national parks, such as Snowdonia, the Brecon Beacons and the Pembrokeshire Coast in Wales; the South Downs and the Lake District in England; and the Cairngorms and the Isle of Skye in Scotland.

However, it's in County Kerry, Ireland, that sees the biggest eclipse in the British Isles archipelago, with Great Skellig — Luke Skywalker's island sanctuary in "Star Wars Episode VII: The Force Awakens" and "Star Wars Episode VIII: The Last Jedi" — seeing a whopping 98% partial eclipse.

When to see the partial solar eclipse in the U.K.

This is a late, low eclipse, and timing matters. The action takes place between 5:59 p.m. and 8:10 p.m. BST, but the main event comes around 7:05-7:13 p.m. BST, when the eclipse reaches its maximum across the U.K. The deeply eclipsed sun will appear above the west-northwest horizon as a thin crescent, hanging like a curved blade, with its tips pointing toward the ground.

It won't get dark — that only happens within the path of totality. However, daylight will feel very subdued with a noticeable dimming.

Location will be crucial. Because the sun will be so low, you'll need a clear, unobstructed horizon — ideally from a coastal viewpoint, hilltop, or open landscape. Get into position early, use proper eclipse glasses and solar filters, and follow the sun as the moon slowly takes its bite.

If you're somewhere rural, it's worth spending the night, which also happens to be the peak of the annual Perseid meteor shower.

Best weather for the partial solar eclipse in the U.K.

Whether the sky is clear on the day is another matter; August may be warm in the U.K., but it's not known for clear skies (as anyone who traveled into the last British path of totality, in Cornwall in 1999, will recall). This is why many British eclipse chasers are perfectly happy that there is no total solar eclipse in the U.K. until 2090, but statistics are not destiny. A single high-pressure system on the day could transform the outlook entirely.

Meanwhile, the path of totality crosses regions with more reliable weather patterns, particularly north-central Spain and the Balearic Islands.

Partial solar eclipse beyond the U.K.

While observers in the U.K. will see a deep partial eclipse, those inside the narrow path of totality — across eastern Greenland, western Iceland and northern Spain — will experience something fundamentally different, if only for a few minutes. In eastern Spain, totality arrives just before sunset, with the fully eclipsed sun hovering only a few degrees above the western horizon. The sun will disappear almost immediately after totality ends.

However, what's been largely overlooked is the scale of the partially eclipsed sunset across Europe and northwest Africa. Across Algeria, France, Germany, Italy, Austria, Poland and beyond, millions will see the sun set while deeply eclipsed. In some locations, maximum eclipse occurs just minutes before sunset; in others, the sun slips below the horizon still significantly covered by the moon. Expect slim crescent suns to be photographed slipping beneath the horizon from across Central Europe.

Consequently, U.K. observers will see the edge of a much larger event — the moon's expansive penumbral shadow stretching across continents. It will be one of the most widely visible and visually striking eclipse phenomena of the decade. According to Time and Date, 283 million people will see at least a 90% partial eclipse.

When is the next partial solar eclipse in the U.K.?

If Aug. 12, 2026, feels like a one-off, it isn't. The U.K. is in the midst of an unusually active spell for partial eclipses, with at least one visible almost every year through the end of the decade. After this deep event comes a more modest partial on the morning of Aug. 2, 2027 — linked to the century's longest total eclipse over North Africa — with a maximum obscuration of 48% in southern England.

On Jan. 26, 2028, attention shifts once again to a partially eclipsed sunset during which up to 56% of the sun will be obscured by the moon. That one will be best seen from western locations such as Cornwall and Wales, while the central path delivers an annular "ring of fire" across Portugal and Spain. The June 12, 2029, eclipse is much more marginal, visible only from northeast England and eastern Scotland as a shallow partial eclipse at sunrise. Finally, on June 1, 2030, another annular eclipse brings a partially eclipsed sunrise to the entire U.K., with up to about 49% of the sun blocked by the moon in the southeast.

Individually, these events are varied — morning, sunset and sunrise eclipses, deep and shallow — but taken together they form a rare sequence for armchair eclipse chasers in the U.K. who likely won't be around for totality 64 years from now.

Be sure to stay up to date with all the latest news with our total solar eclipse live blog, where skywatching editor Daisy Dobrijevic will be sharing her experience of totality from aboard a HX Expeditions cruise ship in the waters off eastern Greenland. Skywatching writer Anthony Wood will also be bringing reports of each eclipse phase from central Spain, as he watches the eclipse accompanied by citizen scientists from the Dynamic Eclipse Broadcast initiative.

The total solar eclipse on Aug. 12, 2026 will sweep across parts of the Northern Hemisphere, offering millions of people a chance to witness one of nature's most spectacular sights.

The path of totality — in which the moon completely covers the sun — begins over the Arctic Ocean, before crossing eastern Greenland, western Iceland and northern Spain. It then passes over the Balearic Islands before ending over the Mediterranean Sea.

Only skywatchers inside this relatively narrow path, just 182 miles (293 kilometers) wide, will experience totality, where day briefly turns to twilight. Here, you'll be able to safely see the sun's outer atmosphere, known as the corona, with the naked eye during the fleeting moment when the moon completely obscures the sun.

A much larger region surrounding the path of totality will instead see an impressive partial solar eclipse. Much of Europe, including the U.K., Ireland, France, Germany, Italy and Scandinavia, will witness the moon take a "bite" out of the sun.

Northern Spain is expected to be one of the most popular destinations for eclipse chasers thanks to its relatively accessible location and the low evening sun on the big day, which could create dramatic views as totality unfolds close to sunset. Greenland and Iceland offer very different experiences, with totality taking place higher in the sky against the nations' spectacular Arctic landscapes.

We'll have reporters on the ground to keep you updated each step of the way. Be sure to follow along on our total solar eclipse live blog to stay up to date with all the latest news and action as Skywatching Editor Daisy Dobrijevic embarks on an eclipse expedition to Greenland with HX Expeditions and Skywatching Writer Anthony Wood heads to Spain to experience the eclipse with NASA's DEB initiative and citizen scientists.

How to watch

Wherever you plan to watch from, remember that it is never safe to look directly at the sun without proper eye protection. Certified solar eclipse glasses or a solar filter fitted to telescopes, binoculars and cameras must be used throughout the partial phases. Only during the brief period of totality, when the moon completely blocks the sun, can you safely remove your eclipse glasses and look directly at the eclipse.

We will also be livestreaming the eclipse here on Space.com; details will be released closer to the time.

Get ready stargazers! We're just one week away from the total solar eclipse on Aug. 12, when millions of stargazers will be treated to a spectacular display as the lunar disk passes in front of the sun, blocking its light.

Roughly 15.2 million people spread across Greenland, Iceland, Portugal, Russia and Spain will be in the path of totality during the total solar eclipse 2026, where the moon will completely hide the sun's disk starting at 12:58 p.m. EDT (1658 GMT), according to Time and Date.

A further 980 million people — approximately 12% of Earth's human population — will bear witness to a partial eclipse, as the lunar disk appears to takes a bite out of the sun.

Solar eclipses occur during the monthly new moon phase, when the lunar disk passes directly between the sun and Earth in its slightly lopsided orbit, casting its colossal shadow over a swathe of our planet's surface.

Viewers in the U.K. and several European countries will see an impressive partial solar eclipse, with around 90% of the sun's surface occulted by the moon as it sinks low on the western horizon. Several northeastern U.S. states, including New York, Maine and Pennsylvania, that sit farther from the path of totality will witness the lunar disk take a small "bite" out of the sun.

You can find out exactly what percentage of the sun will be occulted by the moon using Time and Date's interactive eclipse tracker. Remember, staring directly at the sun during the partial phases of an eclipse can cause permanent vision loss. Be sure to read our guide to safely viewing a solar eclipse, along with our picks of the best solar viewing gear for the 2026 eclipse to ensure that you're ready to enjoy the event.

We will also be bringing you the latest eclipse news and updates from our reporters in the field with our dedicated eclipse live blog. Skywatching Editor Daisy Dobrijevic is on an eclipse expedition to Greenland with HX Expeditions and Skywatching Writer Anthony Wood is heading to Spain shortly to experience the eclipse with NASA's DEB initiative and citizen scientists.

If the eclipse isn't visible from your location, there's no need to worry. You can watch each stage of the total solar eclipse unfold in real time from the comfort of your home. Details of livestreams will be released closer to the time.

August's umbral show is just the opening act of a "Golden Age" of solar eclipses, which will see three total eclipses and three annular "ring of fire" eclipses sweep across Earth between 2026 to 2028.

Meet the Dynamic Eclipse Broadcast Initiative — a passion-driven citizen science endeavour that shares breathtaking views of total solar eclipses while capturing valuable data on the sun's incandescent atmosphere.

At the heart of our solar system is a burning ball of superheated gas 100 times the width of Earth, with a thermonuclear reaction raging at its core. Its radiation and gravity hold the planets in their orbit and allow for the existence of life on our Blue Marble.

Yet despite centuries of scientific scrutiny, many mysteries remain as to the inner workings of our sun and the influence it extends out into the solar system.

What is the DEB Initiative?

One effort to unravel the mysteries and share the beauty of our parent star is being undertaken by the DEB. A network of volunteer solar observers coordinated and guided by professional astronomers from Southern Illinois University Carbondale that's partly funded by NASA and the National Science Foundation.

"We came up with a setup that's portable, that's relatively cheap," Associate Scientist Bob Baer of the Southern Illinois University Carbondale and co-principle investigator of the DEB Initiative explained to Space.com in an interview. "They're about $1,800 once you factor in everything, like the computer, the mount, the telescope, the camera."

During the great American Eclipse of 2024, the DEB had over 80 teams equipped with identical telescopes arrayed across a path of totality that cut through the contiguous United States. Having trained for months, their duty was to keep vigil on the climactic phase of totality, as the moon's silhouette covered the face of our parent star to reveal the sun's golden corona reaching out into the false twilight.

Telescope footage was uploaded in near-real time and included in livestreams that brought the beauty of the eclipse directly to the public no matter where they were — an impressive effort that saw numerous members of the team receive Emmy Awards for their coverage.

Some of the volunteers are also the authors of a scientific paper set to be published in the Astrophysical Journal Letters that tracked the structure and dynamics of the sun's inner atmosphere, or corona, from 11 DEB locations over 49 minutes of evolution.

Outside of eclipses, volunteers also use their telescopes to track asteroids, solar vibrations and powerful flares that blast from the surface of the sun. They even collect data on exoplanet transits, as distant worlds pass between our planet and their parent stars, creating periodic dips in their light.

Having so many volunteers in different places enables a much wider range of data to be collected. "It's the network of telescopes that is the strength of the project," explained Baer. "It's not just one scope."

Is the DEB watching over the 2026 eclipse?

A spectacular total solar eclipse will take place on Aug. 12, as the moon's vast silhouette passes across the solar disk, completely blocking its light across a 182-mile-wide (293-kilometer) swathe of Greenland, Iceland and Spain during the climactic phase of totality.

The DEB will have two teams on hand in the path of totality to observe the eclipse. One will set up in the northwestern Spanish city of Leon, while a second team — led by citizen scientist Charles Greenwald and shadowed by myself — will find the high ground in the Castilian village of Valoria la Buena, 93 miles (150 kilometers) to the southeast.

My conversations with Greenwald have underscored how important passion is to maintaining an initiative like the DEB. The past eight months have seen him travel to Guadalajara, Mexico, multiple times to prepare his team for their expedition to Spain, while helping to test software updates that govern how telescopes will capture the sun over the course of the eclipse.

As in 2024, the data DEB volunteers collect will be uploaded to a server in real time and used in multiple live streams — including NASA coverage — to bring the public closer to the eclipse. But it's also being used as whetstone, a testing ground to hone processes that will be used to document what some are dubbing as "the eclipse of the century", which will sweep across a swathe of Northern Africa on Aug. 2, 2027.

It'll be the longest totality of any eclipse in the 21st century to date, lasting a maximum of 6 minutes and 23 seconds as opposed to the 2 minutes 18 seconds of the 2026 eclipse.

DEB leadership is working on tentative plans for an ambitious 2027 campaign, which could see 27 teams composed of American groups and local observers set up across the path of totality. Baer is hoping to achieve double redundancy throughout the shadow's path, ensuring an uninterrupted view in the event that a group is clouded out, or loses connection.

For plans to unfold on that scale, many moving parts would need to fall into place, both in terms of logistics and funding and, more importantly, in acquiring volunteers from both the U.S. and North Africa.

It's a labor of science, and love. The DEB is planning to start recruiting volunteers for 2027 in the fall of this year, so be sure to keep an eye on the Initiative's website if you're interested in joining their mission to watch over our parent star.

In the meantime, don't forget to check out our explainer article on the Aug. 12 total solar eclipse, along with our roundup of the best solar viewing gear and tips on how to safely observe the sun!

During the eclipse, we'll have live reporting of the event from Skywatching Editor Daisy Dobrijevic as she watches from the the deck of a HX Expeditions cruise ship in the waters off eastern Greenland.

I, meanwhile, will be sharing my experience of totality from the Spanish village of Valoria la Buena, where the eclipse will unfold low in the western evening sky.

NASA is shaking things up for its next mission to research the sun.

The six satellites of NASA's Sun Radio Interferometer Space Experiment (SunRISE) mission are poised to launch to Earth orbit soon, to serve as an early warning system for incoming solar storms. They were originally slated to lift off on a United Launch Alliance (ULA) Vulcan Centaur rocket but have now been assigned a SpaceX Falcon Heavy, according to a NASA mission update.

SunRISE will fly to space as part of a rideshare mission sponsored by the U.S. Space Force's (USSF's) Space Systems Command (SSC). Though it's not stated specifically in the NASA release, that may be a hint as to why the mission's rocket was changed. On its most recent launch, USSF-87, Vulcan experienced an anomaly in one of its solid rocket boosters — the second such incident to occur during the rocket's four launches to date.

Vulcan succeeded in delivering the USSF-87 payload to its designated orbit on that launch, but the recurrence of the booster issue during ascent prompted the Space Force to pause national security launches on Vulcan until it could be addressed. Which mission SunRISE will be manifested on has not yet been released, but SSC has already shifted other launches between Vulcan and SpaceX's Falcon 9, so NASA's change in rockets for SunRISE could indicate either that the mission has been remanifested on a different SSC rideshare, or that another SSC mission has been shifted from Vulcan entirely.

SunRISE is a heliophysics study under the NASA Science Mission Directorate's "missions of opportunity" umbrella and is part of the Explorers Program run by Goddard Space Flight Center in Greenbelt, Maryland. It consists of six small satellites, each about the size of a mailbox. The mini-constellation's mission is led by scientists at the University of Michigan and will be managed out of NASA's Jet Propulsion Laboratory in Southern California.

The half-dozen smallsats will be delivered to an orbit about 22,000 miles (35,000 kilometers) above Earth — just above a geostationary parking altitude — and fly in a giant 10-mile (16-km) "X" formation, each extending its roughly 10-foot (2.5-meter) antenna booms to act as a single large radio telescope to track solar radio bursts. These kinds of bursts travel faster than the energetic particles from a solar storm, and precede their arrival when shot towards Earth.

Powerful solar storms, like the one that hit Earth in January, are capable of disrupting or disabling satellites by interfering with onboard electronics, sensitive instruments and communications systems. If a storm is severe enough, it can pose a radiation threat to astronauts in orbit and even airborne passengers flying near Earth's poles, where the planet's magnetic field is weaker.

SunRISE will help researchers better understand the behavior of incoming solar radio bursts, but the mission won't serve as an alert system by itself. Instead, scientists will use data collected by the spacecraft to improve prediction models for impending space weather, which in turn could lead to mitigation plans to better thwart the effects of such solar events on orbital infrastructure.

Falcon Heavy is SpaceX's heavy-lift launch vehicle, capable of launching up to 58,860 pounds (26,700 kg) to geostationary transfer orbit. It's a triple-booster rocket that consists of three modified Falcon 9 first stages, and has launched 12 times since it debuted in 2018. Four of those have delivered national security payloads to orbit, with the most recent of those, USSF-52, launching in December 2023. Falcon Heavy's most recent flight overall occurred this past April, when it sent the Viasat-3 F3 telecom satellite to orbit.

Falcon Heavy's next mission will lift off with NASA's Nancy Roman Space Telescope, currently set for no earlier than Aug. 30. SunRISE is scheduled to launch later this year, but a more specific launch window has not yet been announced.

For several years now, astronomers who study the sun have faced a little mystery — our star seemed to hold too little silver. Whenever scientists examined the sun's outer layers, they've seen significantly less silver than they've expected to find.

Where, then, did the missing silver go?

As it turns out, this mystery may finally be solved. Newly published research suggests that the sun's missing silver may have been hiding in plain sight all along.

At first, the real mystery might seem to be why you'd seek silver in the sun at all. After all, 98.5% of the sun's mass is made from lightweight hydrogen and helium. Silver is just a tiny fraction of the remaining 1.5%, which also includes traces of other heavy elements like iron and copper.

These trace elements can illuminate the history of the cosmos. Silver is thought to form when dying stars violently explode in supernovas. When astronomers find silver in the sun and other stars, they can retrace the silver's origins and how stars have evolved over the eons.

"By studying the light of stars of different types and ages, we hope to understand where silver is formed in the universe, and how it has been distributed throughout the Milky Way over time," says Sema Caliskan, the lead author of the research and now a postdoc at the University of Liège in Belgium, in a statement.

Silver is particularly interesting because it's also found in utterly ancient meteorites called CI chondrites. These meteorites formed from the same primordial matter that created the sun, 4.6 billion years ago. As a result, when scientists break into CI chondrites that have fallen to Earth, they expect to find silver levels that match those they see in the sun.

Astronomers can measure the latter from afar by looking at sunlight's spectral lines. As light streams out from the sun's heart, it crashes into the atoms of our star's outer layers, which absorb the light at certain wavelengths. Look at a spectrum of sunlight, and you'll see dark lines where light has been absorbed. Atoms of different elements absorb different wavelengths, so each element leaves a distinct fingerprint.

Scientists can pore over these spectral fingerprints to reconstruct what elements created them and in what quantities. Therein lies the mystery: The sun seemed to contain much less silver than CI chondrites would indicate. This missing silver is a source for confusion in the sun's history.

Caliskan and her colleagues wondered if astronomers were missing something. They could not visit the sun in person, but they could still find where the silver might be hidden by simulating the sun's atoms on a computer. If they could create a high-silver model that still spawned the low-silver spectral lines, that model could be a good guess for the silver's whereabouts.

Other scientists had tried this before to limited success, but their simulations had been relatively simple. As light strikes an atom, the light has all sorts of intricate effects on the atom's innards. These effects can alter how the atom absorbs the light and, therefore, change how astronomers see that light.

Past models hadn't accounted for many of these tricky "non-equilibrium effects", because simulating them is far easier said than done. They're messy and complex and they vary a great deal from atom to atom.

In fact, no known scientists had ever tried to simulate a silver atom with non-equilibrium effects before Caliskan and her fellow investigators took on the challenge. They tried with their best guesses and the power of the Tetralith supercomputer in Linköping, Sweden.

Indeed, these non-equilibrium effects seem to explain the silver mystery. Based on their model, Caliskan and colleagues calculated that the sun holds 55% more silver than astronomers have measured.

This isn't a perfect match for the CI chondrites, but it's close enough that investigators can rule out any extraordinary cause. Instead, the missing silver may have been right there, in the sun all along, simply occluded from astronomers' view by tricks of physics. Next, Caliskan and colleagues plan to use this method to simulate other types of stars.

They published their work in the journal Astronomy & Astrophysics in July 2026.

The most powerful solar storms to strike Earth may pack a bigger punch than scientists realized, according to a new study that suggests the impacts of extreme space weather have been underestimated.

Researchers found evidence that the apparent upper limit on Earth's response to the strongest solar storms may be an artifact of how solar wind has been measured rather than a true physical ceiling. If confirmed, the findings suggest that rare "once-in-a-thousand-year" geomagnetic storms could have a greater impact on modern technology than current estimates indicate, according to a statement.

"Our planet's magnetic field does a really great job of protecting us against many space weather effects and so they often just show up as glitches or beautiful aurora," Maria Walach, co-author of the study from Lancaster University, said in the statement. "There are however extreme cases."

Solar storms occur when eruptions from the sun, such as coronal mass ejections and solar flares, send clouds of charged particles hurtling toward Earth. While they can produce spectacular auroras, they can also disrupt satellites, GPS, radio communications and power grids.

History has shown the damage even less extreme storms can cause. The 1859 Carrington Event, the strongest geomagnetic storm on record, disrupted telegraph systems around the world and pushed auroras from their usual high-latitude skies near the Arctic and Antarctic to locations as far south as the tropics. Another powerful storm in 1989 collapsed Quebec's power grid, leaving millions without electricity, while the 2003 "Halloween storms" disrupted satellites, GPS and radio communications.

While the study doesn't suggest that an unprecedented solar storm is imminent, it argues that scientists may need to rethink how they estimate the severity of the rarest events — an increasingly important challenge as modern society grows more dependent on satellites and other vulnerable technologies.

The researchers traced the apparent upper limit to where most solar wind measurements are collected. Many observations of extreme events come from spacecraft near the Sun-Earth Lagrange Point 1 (L1), about 1 million miles (1.5 million kilometers) upstream of Earth. Because the strongest solar wind tends to weaken somewhat before reaching Earth, comparing L1 measurements with conditions at our planet can make it appear that Earth's upper atmosphere stops responding to increasingly intense solar wind, even when it does not.

To test that idea, the team analyzed more than one million solar wind measurements collected by NASA spacecraft orbiting much closer to Earth, where the solar wind directly interacts with our planet's magnetic field. Those observations showed that electrical currents flowing through Earth's upper atmosphere continued to increase alongside stronger solar wind, with no sign of the previously assumed upper limit. The results suggest that exceptionally powerful solar storms could generate stronger geomagnetic disturbances — and greater impacts on satellites, communications systems and power grids — than earlier estimates predicted.

"Fortunately, these very extreme cases are rare, but this also means we have limited data to work with and only time will tell what happens at the very extreme one-in-a-thousand-year kind of event," Walach said in the statement.

The study comes as the sun remains near the peak of its roughly 11-year solar cycle, known as solar maximum, when sunspots, solar flares and coronal mass ejections become more frequent. During the current cycle, strong geomagnetic storms have repeatedly sent auroras far beyond their usual polar skies.

In May 2024, the strongest geomagnetic storm in more than two decades illuminated skies across much of the United States and Europe while causing intermittent disruptions to high-frequency radio communications, GPS-guided equipment and some satellite operations. Although significant, that event was far less powerful than the Carrington Event — or the even rarer storms the new study suggests may be possible.

The findings were published July 15 in the journal Nature.

On Aug. 12, I get to fulfil a lifelong ambition. I'll take a flight to Madrid and travel northwest to the city of Valladolid by rail, before striking out for Valoria la Buena — a charming town in central Spain with a population of less than 1,000.

There, I'll bear witness to one of the most spectacular naked eye shows that the solar system has to offer: a total solar eclipse. My first total solar eclipse.

Don't get me wrong. I've been obsessed with eclipses my entire life. I just haven't found myself in the right place at the right time to experience totality until now. 10-year-old me came pretty close during a deep partial eclipse in 1999, when I caught a fleeting glimpse of the moon's silhouette taking a bite out of the sun in the cloud-ridden skies over the United Kingdom.

Smash cut 20-something years later and I'm inexplicably the Skywatching Writer for Space.com, where one of the major perks of the job is being sent to report on eclipses. Things aligned quite nicely.

For the 2026 eclipse, I'll be joining a volunteer team from NASA's Dynamic Eclipse Broadcast (DEB) Initiative led by citizen scientist Charles Greenwald.

The DEB is a network of enthusiastic solar observers led by professional astronomers who use standardized telescopes and software to share inspiring eclipse imagery to the public, while also capturing valuable scientific data on the sun's disk and golden atmosphere.

It was Greenwald who scouted Valoria la Buena as a prime location to observe the eclipse. He's since been hard at work liaising with DEB initiative leadership to test software updates and troubleshoot other issues, while also travelling to Mexico to help train student members of the team ahead of their expedition to Spain. Two more eclipse enthusiasts are due to join the group once it arrives in Madrid, making it a wonderfully international affair.

Less than a month out, things are pretty settled, and a kind of nervous anticipation has taken hold. Flights and trains are booked, and I have a pair of Celestron EclipSmart 10x42 binoculars and the EclipSmart 3-Piece Solar Eclipse Observing and Imaging Kit, courtesy of Celestron. Also hats and an ungodly amount of suntan lotion. I'm bald after all, so the sun is my greatest natural predator.

Of course, preparations can only get you so far. Once we get to Valoria la Buena on Aug. 10 there'll still be important work to do. The first order of business for Charles and his DEB team will be to stake out a location with a clear line of sight to the west for their equipment. Totality will occur with the sun less than 10 degrees above the horizon — roughly the width of your clenched fist held at arm's length — so line of sight will be everything.

We'll also be at the mercy of the weather. Clouds could easily arrive to hide the cosmic show from view — especially with the eclipse so low on the horizon. The DEB team also has to find a spot with good connectivity, which will allow them to broadcast near-live images of our parent star for the public to enjoy and scientists to pore over.

All being well, myself, the DEB team and over 15 million others in the path of totality will bear witness to a heartstopping display of orbital mechanics that crescendos with the fleeting artificial night of totality, as the moon blocks the last sliver of the sun from view. Space.com's Skywatching Editor Daisy Dobrijevic will also be on hand to report on the total solar eclipse as it unfolds in the skies over Greenland.

We can't wait to share our experiences with you. Be sure to stick with Space.com to discover everything there is to know about the Aug. 12 total solar eclipse, along with details on how to watch it online, which will be published closer to the event!

You should also read our guide to safely observing the sun, to ensure that you're ready to enjoy the eclipse, and our roundup of the best solar viewing equipment available in 2026 if you're looking for safe, quality gear.

Sometimes weeks go by without anything notable happening in the sky. Then along comes something spectacular, like a total solar eclipse, the peak of a major meteor shower or a bright planet reaching a landmark moment in the evening sky. On Wednesday, Aug. 12, 2026, all three occur almost simultaneously. As a bonus, if you are under a dark sky for the Perseids, the Milky Way's bright central regions will stretch across the southern sky by around midnight.

Exactly what you'll see of the eclipse depends on where you are on Earth. From within a narrow 180-mile-wide path of totality across eastern Greenland, western Iceland and northern Spain, a total solar eclipse will briefly turn day into night for lucky locals and intrepid eclipse chasers. Across the U.K., millions will see a partial eclipse of the sun, ranging from 90% to 95%. Across Europe and northwest Africa, an equally deeply eclipsed sun will peak at sunset, creating a truly strange sight. Minutes later, brilliant Venus reaches dichotomy — appearing exactly half-lit in telescopes, while to the naked eye it blazes at magnitude -4.4 in the western twilight. A few hours later, the annual Perseid meteor shower reaches its peak.

Wherever you are, there will be something worth looking at. Here's exactly what will happen, where and when, depending on where you are (times are from Time and Date).

Iceland or Greenland: a total solar eclipse … and aurora?

If you've traveled to (or live in) western Iceland, or you're booked on an expedition cruise ship on Aug. 12, you're in for a treat. The point of maximum eclipse — 2 minutes 18 seconds — is off the coast of Iceland, accessible by ship, but likely not by many. It's possible that expedition ships in the lower reaches of Scoresby Sund, Greenland, will experience the most totality, with 2 minutes 17 seconds possible at 4:36 p.m. WGST, with the eclipse 25 degrees above the west-southwest. Here, the sun will set at 10:15 p.m., with the darkest time about 12:50 a.m. — there is no truly dark night, just all-night civil twilight. That makes the Perseids and aurora unlikely to be seen even if they're present. Ditto Venus — Greenland is too far north.

In Iceland, totality will begin between 5:43 and 5:50 p.m. GMT, depending on the exact location. It will last longest in regions farthest west, with 2 minutes 13 seconds at Látrabjarg in the remote Westfjords (5:44 p.m.) and 2 minutes 10 seconds at the westernmost coast of Snæfellsnes Peninsula (5:45 p.m.). The eclipse will be 25.5 degrees above the west-southwest. The sun will set at 9:53 p.m. in Reykjavík, with the darkest window from 11:00 p.m. to 4:00 a.m. (and the darkest time 1:30 a.m.). That makes Perseids and aurora possible — though summer twilight often limits visibility. However, Venus will not be visible after sunset.

Spain: Totality, Venus and the Perseids

For anyone within Spain's path of totality, Aug. 12 promises to be one of the greatest days of skywatching imaginable. The main event comes late in the day as the moon completely covers the sun. In parts of northern and eastern Spain, totality will occur with the sun hanging low above the western horizon, creating one of the most photogenic eclipse scenarios of the century.

In Spain, totality will begin between 8:26 and 8:33 p.m. CEST, depending on the exact location. Its maximum duration in Spain will last longest in regions farthest northwest, with 1 minute 50 seconds at Playa de la Escaladina in Galicia (8:26 p.m.), where the eclipse will be 11 degrees above the west-northwest. It will be at its shortest, at 1 minute 36 seconds, at Bellavista, Mallorca, one of the Balearic Islands (8:31 p.m.). The eclipse will be just a couple of degrees above the west-northwest. The sun will set at 9:16 p.m. in Madrid, with a dark night from around midnight through 4:40 a.m. CEST. The darkest part of the night — and the point when the radiant point Perseus will be high above the horizon — will be around 02:00 a.m. CEST.

Unless there's a whopping solar storm (unlikely), concentrate on the Perseid meteor shower, rather than hoping for aurora. Light pollution is irrelevant for a total solar eclipse, but if you've cross-referenced your eclipse-viewing sight with a Light Pollution Map, you'll be in Bortle 4 skies in rural Spain, ready for a potentially unforgettable Perseids (the solar eclipse means by definition that it's taking place at new moon, after all). Under rural Spanish skies, particularly in dark-sky regions away from towns and cities, observers could see 30 to 50 meteors per hour, with occasional bursts producing even more.

It might be wise to have an afternoon nap before the eclipse — it could be a long, exciting night if skies are clear.

U.K: Deep eclipse, Venus and the Perseids

The path of totality misses Britain entirely, but Aug. 12 will still be a remarkable day. Across most of the U.K., more than 90% of the sun will be covered by the moon, with maximum eclipse shortly after 7 p.m. BST. The sun will hang low above the west-northwest horizon as a narrowing crescent, so the best locations will be coastal viewpoints, hilltops and open landscapes with clear western horizons. London, Manchester and Glasgow all experience about 91% coverage, while Cardiff reaches 93%. The deepest eclipse will be seen in the far southwest, with 96% coverage in the Isles of Scilly and almost 96% at Land's End in Cornwall.

Although it will not become as dark as during totality, observers may notice a subtle drop in temperature and a strange dimming of the landscape. Shadows will soften, colors will become muted, and daylight will take on an unusual quality that many first-time eclipse watchers find surprising.

Once the eclipse ends, Venus becomes the next target. Look west after sunset for the dazzling Evening Star. Venus is only days from its greatest elongation and near its best evening appearance of 2026, making it hard to miss. Even a small telescope will reveal its half-lit phase. The Perseids will then peak during the early hours of Aug. 13.

Western Europe: Eclipsed sunset, Venus and the Perseids

For millions of people across Western Europe, Aug. 12 offers a slightly different spectacle. Instead of totality or a partial eclipse in late afternoon, many locations will witness a deeply eclipsed sun setting below the horizon. An eclipsed sunset is surprisingly rare, and particularly one this deep. In some places, more than 90% of the sun will be obscured as it approaches the horizon, creating a dramatic crescent-shaped sunset. In places such as Corsica, the Ligurian coast, Venice, the Alps and parts of central Europe, photographers will have the chance to capture one of the most dramatic sunset eclipses visible anywhere this decade.

With Venus visible across Europe after sunset, as well as the Milky Way and the Perseids peak, Aug. 12 will effectively become an all-night astronomy festival across Europe.

North America: Partial eclipse, Venus and the Perseids

The total solar eclipse — and a deep partial eclipse — may belong to Europe, but North America gets its own small version of the event. A partial solar eclipse will be visible from Alaska to New England, touching 26 U.S. states and every Canadian province. While the eclipse is modest compared with North America's recent total eclipses, millions of people will still be able to participate in the global event.

The deepest U.S. eclipse occurs in Alaska, where Fairbanks will see about 37% of the sun covered and Anchorage almost 28% (8:21 a.m. AKDT). In the Northeast, Maine gets the best view, with about 28% obscuration (1:50 p.m. EDT), while Boston sees 16% (1:55 p.m. EDT) and New York City about 10% (1:54 p.m. EDT). In Canada, the eclipse becomes considerably more impressive. Iqaluit, Nunavut, will see 61% of the sun covered (1:24 p.m. EDT), while St. John's, Newfoundland, will experience more than half of the sun obscured (3:35 p.m. NDT). Every Canadian province will see at least some part of the eclipse. Remember that eclipse glasses are still essential, even for small partial eclipses.

One month from today, millions will turn their eyes to the skies for one of the most anticipated skywatching events of the year: the total solar eclipse on Aug. 12, 2026.

The eclipse will sweep across parts of Greenland, Iceland and Spain, briefly turning day into night for those lucky enough to be within the narrow path of totality.

It's been a long time coming for European skywatchers, as the event marks Europe's first total solar eclipse since 1999.

Where can I see the total solar eclipse?

If you're hoping to experience totality, now is the time to finalize your plans. The path of totality crosses Greenland, Iceland and northern Spain, with maximum eclipse lasting up to 2 minutes and 18 seconds.

Spain is expected to be one of the most popular destinations thanks to its favorable weather prospects, though it's not without a catch! Viewers will need to secure a clear view of the western horizon because the eclipsed sun will sit very low in the sky during totality.

Will I see the eclipse from where I live?

Not inside the path of totality? Don't worry. A spectacular partial solar eclipse will be visible across much of Europe, with more than 90% of the sun covered from locations including London, Paris and Dublin.

If you're still deciding where to watch, we have several guides on the best viewing locations close to popular Spanish holiday destinations, the best Spanish beaches, and the best places to view the eclipse overall.

How we will be covering the eclipse

Over the coming weeks, Space.com will bring you everything you need to prepare for eclipse day. We'll publish viewing guides, safety advice and information on how to watch the eclipse online.

Closer to the event, we'll launch a dedicated live blog covering the latest eclipse news and insights from our reporters in the field.

Skywatching Editor Daisy Dobrijevic will join an eclipse expedition to Greenland with HX, while Skywatching Writer Anthony Wood will travel to northern Spain with the DEB initiative and citizen scientists to report firsthand from the path of totality.

For decades, astronomers have debated whether Earth's fate was tied to the sun's. When the star exhausts the hydrogen fuel that powers it about 5 billion years, it will swell into a red giant large enough to engulf Mercury and Venus — and, several studies have suggested, Earth as well.

New research, however, suggests our planet has a better chance of escaping that fiery end than previously thought. Using updated models of how aging stars interact with their planets, researchers found that the gravitational forces drawing Earth toward the expanding sun are weaker than older models predicted. That would give the planet more time to drift outward as the dying sun sheds its outer layers into space, potentially avoiding engulfment altogether.

The finding does not guarantee Earth's survival. Instead, researchers say it shifts the biggest uncertainty from how strongly the expanding sun tugs on planets to the poorly understood variable of how much mass the star will lose during its final stages of evolution.

"The largest uncertainty no longer comes from the tidal calculations, but from how much mass the future sun will lose," study lead author Mats Esseldeurs of the KU Leuven's Institute of Astronomy in Belgium said in a statement. "Observations of sun-like giant stars currently point towards Earth's survival, but we need better observations before we can be certain."

When stars like the sun exhaust their core hydrogen and balloon into massive red giants, they trigger a cosmic tug-of-war between expanding tidal forces pulling planets inward and shedding stellar weight pushing them outward, which ultimately decides whether nearby worlds are engulfed or saved.

This planetary push-and-pull unfolds in two stages. As the sun expands, gravitational tides act like a subtle brake, slowly draining Earth's orbital energy and pulling the planet inward. At the same time, the dying star sheds vast amounts of gas through powerful stellar winds, eventually losing about half its mass. As the sun grows lighter, its gravitational grip weakens, pushing the surviving planets outward into a wider orbit that could double their distance from the star, according to NASA.

"The fate of Earth depends on a delicate balance between these two effects," Esseldeurs said in the statement. "If tidal interactions dominate, Earth is engulfed. If mass loss dominates, Earth escapes to a wider orbit."

Previous studies reached different conclusions mostly because they treated those competing processes differently, Esseldeurs and his team argue. A few of those studies neglected tidal interactions altogether, while others relied on simplified prescriptions developed decades ago that predicted a much stronger inward pull, according to the study.

Instead of relying on those older formulas, the new study uses updated calculations of tidal forces based on the shifting internal structure and dynamics of aging stars — which the team says allowed it to precisely account for both tidal friction and shifting stellar winds — before testing the results against a range of possible mass-loss rates for the sun's final giant phase.

The results suggest that even with the weaker inward gravitational pull, Mercury and Venus are unable to outpace the expanding sun and are inevitably engulfed, while Earth and Mars migrate safely through both giant phases, leaving our planet to eventually settle into a broader orbit around the white dwarf remnant the sun will leave behind, the study found.

The picture is far from settled, however. Because astronomers still cannot precisely observe how rapidly sun-like stars lose mass late in life, "the ultimate fate of the Earth remains uncertain," the researchers write in the new paper.

By factoring in real-world mass-loss rates from L2 Pup — a red giant star roughly 183 light-years away that was used as a proxy for our future sun due to its similar mass — the researchers confirmed that Earth will drift outward just quickly enough to avoid being swallowed, tipping the scales toward survival over destruction, the study notes.

For us humans, the finding offers academic comfort rather than practical salvation. Most scientists agree that as the sun ages, it will steadily grow hotter, boiling Earth's oceans and rendering the planet completely uninhabitable in about 1 billion years, long before the sun begins to expand.

Yet even if humans aren't around to witness it, tracking Earth's ultimate survival provides important context for how planetary systems evolve as their stars age, a framework that researchers say will be further refined by future observations of dying, sun-like stars.

"This will enable us to conduct population studies of the planetary orbital evolution around evolved stars," the researchers wrote in the paper, "and help us to constrain the future evolution of the Earth-sun system."

The study was published in June in the journal Astronomy & Astrophysics.

The mystery of how the sun's corona, which is its outer atmosphere, reaches millions of degrees could have a surprising explanation: cosmic dust riding the magnetic waves carrying plasma on the solar wind.

"For decades, researchers have focused mainly on how electrons, ions, magnetic fields and plasma waves transport and dissipate energy in the solar atmosphere," said lead researcher Syed Ayaz of the University of Alabama in Huntsville in a statement. "Our work adds a new ingredient to this picture: dust grains."

The finding came courtesy of NASA's Parker Solar Probe, which has flown closer to the sun than any other spacecraft, skirting the corona at a distance of 6.1 million kilometers (3.8 million miles). If you've ever witnessed a total solar eclipse, or even seen a photograph of one, then you will be familiar with the corona — the ghostly tendrils of light that surround the eclipsed sun. Those tendrils are formed from plasma, or ionized gas, at temperatures in excess of a million degrees Fahrenheit, compared to the sun's visible surface, the photosphere, which radiates at about 9,932 degrees Fahrenheit (5,500 degrees Celsius). At those temperatures, the photosphere outshines the corona only because the plasma in the corona is so sparsely distributed. This is why the only time we can see the corona is during a total solar eclipse, when the photospheric glare is blocked.

Parker does not carry a cosmic dust detector, and that's because until now dust has not been considered a serious component of the solar atmosphere. Indeed, in the high temperatures of the solar corona it had been thought that dust could not survive for very long and would therefore have no impact.

However, Parker does host a bunch of antennas and magnetometers collectively referred to as the FIELDS experiment, designed to measure the electromagnetic field and radio emissions in the solar corona. The antennas kept picking up unexpected spikes in voltage, which according to Ayaz and his team are produced by clouds of charged particles created when tiny dust grains slam into Parker at high velocity.

These dust grains have accrued an electrostatic charge, which can interact with the electromagnetic field carried by the solar wind as it leaves the sun, which in turn can influence waves of plasma reverberating through that electromagnetic field called Alfvén waves.

There are two possible, competing ways in which dust can affect the Alfvén waves, which in turn could determine how energy is dumped into the corona, heating it. On one hand, the mass of the dust can act to provide extra inertia to the plasma as it rides the solar wind, allowing the plasma energy to be transported across wider distances. On the other hand, the electric charge on the dust grains can bolster the interactions between charged particles in the plasma, the Alfvén waves and the solar electromagnetic field.

"If dust mass dominates, [Alfvén] wave energy may travel farther into the corona," said Ayaz. "If dust-charge effects dominate, the energy may be released more locally as particle heating."

The balance between these two effects can therefore control where and when energy is deposited into the corona, focusing it in areas and causing temperatures there to rise dramatically.

Future solar missions are now going to have to start taking dust into account, said Ayaz, with dedicated detectors designed to measure dust's properties close to the Sun.

"The bigger question is fascinating," said Ayaz. "Is dust simply passing through the near-Sun environment, or is it helping shape how electromagnetic energy becomes heat and solar-wind motion?"

The new discovery was reported on July 1 in The Astrophysical Journal.

Astronomers have used the James Webb Space Telescope (JWST) to observe an oddball gas giant exoplanet orbiting a dead star, a white dwarf, located some 80 light-years away. This "life after death" system gives scientists a portentous vision of what the solar system may look like in around 6 billion years after the sun has exhausted the hydrogen in its core, shed its outer layers, and left behind a smoldering white dwarf stellar remnant.

Prior to the final stages of that transformation, our star will have become a red giant, swelling out to many times its original radius, swallowing the inner rocky planets including Earth but leaving the outer planets  — although changing them irrevocably. Reflecting this, the white dwarf at the heart of this research is orbited by a Jupiter-sized exoplanet, designated WD 1856 b.

As WD 1856 b orbits its dead parent star, it crosses or "transits" the face of this white dwarf, known as WD 1856+534. By observing these transits with the JWST, the team was able to measure the mass and temperature of this Jupiter-like planet while also observing the composition of its atmosphere. To their surprise, they found WD 1856 b is hotter than expected. They also discovered how this planet came to have such an unusually tight orbit around its host white dwarf star.

"We're used to looking back in time when we use telescopes, but this is the first time we have been able to look forward to what might happen to the outer planets around the remnant of a sun-like star; it's like using a time machine to peer into the distant future of our solar system," team leader Ryan MacDonald from the University of St Andrews in Scotland said in a statement. "This is just the beginning of our exploration of planets orbiting dead stars with Webb, and the search for further planets orbiting white dwarfs is ongoing.

"Our results show that stellar death is not the end  — some planets experience a vibrant and lively future after the death of their star."

The team's research was published on Wednesday (July) in the journal Nature.

Survivor planet is a real oddball

The gas giant WD 1856 b was first discovered in 2020 by NASA's exoplanet-hunting spacecraft TESS (Transiting Exoplanet Survey Satellite) and the Spitzer Space Telescope. TESS detects exoplanets using the tiny dips in starlight they cause as they transit their host stars, blocking starlight.

This was the first intact planet ever discovered closely orbiting a white dwarf. What immediately stood out about WD 1856 b was how close its orbit is to its white dwarf host. The orbit is around 2% the size of Earth's orbit around the sun and takes just 1.4 Earth days to complete.

"The planet is quite the oddball. It's about the size of Jupiter, but the white dwarf it orbits is the size of Earth, so the planet is seven times larger than its star," MacDonald said.

The planet couldn't have always been in such a close orbit to its star. If it had, it would have been obliterated when the star transformed into a red giant before shedding its puffy outer layers and leaving behind a white dwarf.

"The big question is how WD 1856 b ended up where it is today, and there are two theories," team member Christopher O'Connor of Northwestern University said. "One is that the planet was swallowed by the host star as it was dying, and managed to survive on the inside. The other is that the migration took place due to the gravitational effect of other objects in the system. The white dwarf is part of a triple star system, and the outer companion stars could have influenced WD 1856 b's orbit."

The clue that allowed the team to differentiate between these migration mechanisms was the temperature of WD 1856 b, which at 260 degrees Fahrenheit (127 degrees Celsius) is about 240 degrees hotter than it would be if its only source of heat were the light from its white dwarf parent star.

With no energy available to warm the planet to these temperatures, the team reasoned that the temperature must be a residual effect of prior warming either from being engulfed by the red giant or during an inward migration. Using observations of the planet's mass of between four and 11 times that of Jupiter, the team was able to model how it would have cooled over time.

MacDonald and colleagues determined that WD 1856 b was likely heated up around 3 billion to 5.5 billion years ago. Its host star has been a white dwarf for longer than that, which means the exoplanet was safe during the star's destructive red giant phase, and moved into its tight orbit afterwards.

"As the planet moved inwards, its interactions with the strong gravity of the white dwarf will have caused it to warm up considerably, and it has been cooling ever since," O'Connor said.

The results indicate that Jupiter could move closer to the sun after the violent drama of its red giant phase and the destruction of the inner solar system. The findings also demonstrate the incredible observing power of the JWST and how the $10 billion space telescope is still discovering things no other instrument can.

"White dwarfs like WD 1856 are exceptionally dim compared to the planet-hosting stars we normally observe with the JWST," team member Victoria Boehm of Cornell University said.

"To make things even harder, the planet's transit only lasts 8 minutes, so it's very much if you blink you miss it! Capturing enough light to see WD 1856's spectrum, while also doing so quickly enough to not miss the transit, is something only Webb can do."

Heads up aurora chasers! The sun has been very busy.

After unleashing an X1.1 solar flare on June 30, the sun continued its outburst by firing off 10 M-class solar flares in 24 hours! Several of these eruptions were accompanied by coronal mass ejections (CMEs) that appear to be at least partially Earth-directed.

Exactly how many of these solar storms will reach Earth (and how effective they will be) is still being calculated, but space weather forecasters say the coming days could bring heightened geomagnetic activity and increased chances of seeing the northern lights.

Solar physicist Tamitha Skov described the recent activity as a "Machine-gun sun" in a recent post on X, writing that more than five solar storms are on their way to Earth, with at least three offering "good chances" for aurora displays.

"NOAA and NASA model predictions do not show all the storms yet," Skov wrote, explaining that the rapid succession of eruptions has made them difficult to model. Skov added that the first storm could arrive before 8 a.m. EDT (1200 GMT) on July 3, with G2 or stronger geomagnetic storm conditions possible if the incoming CMEs carry a favorable magnetic orientation, allowing them to connect more efficiently with Earth's magnetic field.

According to NOAA's Space Weather Prediction Center, at least one CME from July 1 appears to have an Earth-directed component, although further analysis is still underway. The agency continues to forecast moderate (G2) geomagnetic storm conditions beginning tonight, driven primarily by the CME launched during the June 30 X-class flare, while noting that additional CMEs from the barrage of July 1 eruptions are still being analyzed.

Will the northern lights be visible?

The forecasts are looking increasingly promising for aurora chasers.

NOAA's latest forecast calls for moderate (G2) geomagnetic storm conditions around 8-11 p.m. EDT tonight (0000-0300 GMT July 3), with minor (G1) storm conditions for much of July 3. That could push the northern lights farther south than usual, potentially making them visible across parts of the northern U.S., including New York and Idaho, provided skies are dark and clear.

Exactly how impressive any display becomes will depend on how the incoming CMEs interact with one another and, crucially, the orientation of their magnetic fields when they arrive. When a magnetic field within a solar storm aligns the right way, it can more effectively transfer energy into Earth's magnetic field, producing stronger geomagnetic storms and brighter auroras.

However, nights remain short for observers in the northern hemisphere and lingering twilight could make auroras harder to spot.

That being said, it's worth making sure your cameras are charged and your aurora alerts are switched on. With multiple CMEs heading our way, there could be some natural fireworks lighting up the skies this July 4 weekend.

A restless Earth-facing sunspot unleashed a powerful X-class solar flare on June 30, triggering radio blackouts across parts of North America.

The X1.1 solar flare erupted from sunspot region AR4479, peaking at 4:50 p.m. EDT (2050 GMT) according to NOAA's Space Weather Prediction Center.

The intense burst of X-rays released during the eruption reached Earth in just over 8 minutes, triggering strong (R3) radio blackouts across the daylight side of Earth. This mainly affected high-frequency radio users across parts of North America who may have experienced temporary signal degradation or brief communication outages while the flare was at its strongest.

The eruption also launched a coronal mass ejection (CME) — a huge cloud of magnetized solar plasma hurled into space. Initial observations suggested most of the material was traveling northward, limiting the chances of a significant Earth impact.

However, after further analysis, NOAA's Space Weather Prediction Center issued a Moderate (G2) geomagnetic storm watch for July 3, indicating that at least part of the CME could land Earth with a significant blow.

Will we see the northern lights?

When Earth-directed, CMEs can interact with our planet's magnetic field and spark geomagnetic storms, which can produce dazzling northern lights displays.

A G2-level storm is capable of pushing the northern lights farther south than normal. According to NOAA, auroras could become visible across some northern and upper Midwestern U.S. states, from New York to Idaho, provided skies are dark and clear.

Exactly how impressive the display becomes will depend on the strength of the CME and, crucially, the orientation of its embedded magnetic field when it arrives. If conditions are favorable, the natural light show could provide an extra helping of "fireworks" just in time for the July 4 weekend.

What are solar flares?

Solar flares are sudden bursts of energy released when magnetic fields around sunspots become twisted and reconnect. They are ranked using five classes — A, B, C, M and X — with X-class flares representing the most powerful eruptions.

What are CMEs?

CMEs behave a little differently. Unlike the radiation from a solar flare, which reaches Earth at the speed of light, these clouds of charged particles typically take one to three days to reach us. If they arrive in the right magnetic orientation, they can disturb Earth's magnetic field and trigger geomagnetic storm conditions.

Editor's note: This story was updated at 9:30 a.m. EDT on July 1 to reflect NOAA's latest forecast, including the issuance of a G2 (Moderate) geomagnetic storm watch for July 3 following further analysis of the accompanying coronal mass ejection.

Scientists have discovered that dying stars don't go down without a fight. New research suggests that when stars like the sun enter their red giant phase, they spit out blobs of plasma and receive a corresponding "kick" in the opposite direction.

Stars become red giants when the hydrogen in their cores is exhausted, and that core collapses. This results in the outer layers of the star where nuclear fusion is still occurring, puffing out and expanding the star's radius to as much as 100 times its original size. Those outer layers are eventually lost altogether, leaving behind a dense stellar remnant known as a white dwarf. The sun itself will undergo this transformation in around 5 billion years, swelling out to around the orbit of Mars and engulfing the inner rocky planets, including Earth.

California Institute of Technology researcher Jim Fuller calculated that before a star becomes a white dwarf, it will receive around 10,000 little kicks over the course of hundreds of thousands of years. The cause of these kicks is the ejection of blobs of plasma from the red giant stars.

"In this model, blobs of matter are chaotically being ejected from the surface of the bloated stars in an asymmetric fashion," Fuller said in a statement. "And every time that happens, the star gets a little kick in the opposite direction. Like Newton said, for every action there is an equal and opposite reaction."

The blobs of plasma will be chaotically ejected in random directions, but this will still result in an overall net push on the red giant, a phenomenon mathematicians call a "random walk." This is akin to randomly flipping a coin to decide whether to move north or south and still eventually finding yourself moved from your starting position.

Fuller determined that for a red giant, this random walk would see a movement in a random direction at a speed of around 2,200 mph (3,540 km/h). This may seem like a lot, but it pales in comparison to the kicks received by massive stars that explode as supernovas.

The lack of an explosion in the transformation of an average-sized star into a white dwarf makes these events less dramatic, but we have still seen evidence of this happening.

Caltech researcher Kareem El-Badry has previously discovered that widely separated binaries are less common in cases when one star has undergone the transformation into a white dwarf. One possible explanation is that repeated kicks during the red giant phase eventually break apart these loosely bound stellar pairs.

"If the orbital speed of the binaries is less than the kick speed, the wide binaries will become gravitationally unbound," Fuller said. Fuller's model also suggests something that astronomers are yet to see. He predicts that in some cases the kicks received by a red giant could send it pinballing toward a stellar companion, causing a massive explosion when the two collide.

Astronomers could now search the cosmos for such events, the discovery of which would help verify Fuller's model.

Fuller's results were presented at the 248th meeting of the American Astronomical Society in Pasadena. The study has been submitted to the Proceedings of the Astronomical Society of the Pacific.

A bold telescope-rescue mission is set to launch later this month, and you can learn all about it today (June 17).

That mission will be conducted by Link, a robotic servicing spacecraft built and operated by the Arizona-based company Katalyst Space Technologies. Link will meet up with NASA's Neil Gehrels Swift Observatory in the final frontier, raising the telescope's orbit to give it more time to study the heavens.

NASA and Katalyst representatives will discuss the plan today, during a press conference that starts at 11 a.m. EDT (1500 GMT). You can listen live here or directly via NASA.

Participants will be:

• Shawn Domagal-Goldman, division director, Astrophysics, NASA Headquarters in Washington
• Brad Cenko, principal investigator, Swift, NASA's Goddard Space Flight Center in Greenbelt, Maryland
• Kieran Wilson, principal investigator, LINK, Katalyst Space
• Robert Lamontagne, vice president, strategic partnerships, Katalyst Space
• Wes Collier, vice president, launch systems, Northrop Grumman

Swift launched to low Earth orbit in 2004 to hunt for gamma-ray bursts, the most powerful explosions in the universe. The telescope is still perfectly capable of doing this important job, but Earth's atmosphere is dragging it down toward a fiery death.

Swift doesn't have a propulsion system to fight this downward pull, so it needs some help — which is where Katalyst comes in. Last fall, NASA announced it had tapped the company to raise Swift's orbit.

It's an unprecedented ask: No private spacecraft has ever linked up with a robotic U.S. government satellite. And time is of the essence; some models predicted the observatory could come back to Earth as soon as this summer.

Katalyst has acted fast, getting Link ready for a launch later this month from the Marshall Islands in the Pacific. (NASA has not yet announced a target date). Link will fly aboard a Northrop Grumman Pegasus XL rocket, an air-launched vehicle that will be carried aloft by a plane.

Scientists may have finally seen the sun telegraph an eruption hours before it happened — and the one caught was one of our star's most powerful explosions.

Drawing on a rare dataset collected in the hours leading up to a massive solar flare, scientists identified a series of changes in the sun's atmosphere that offer new clues about how major eruptions begin. Eventually, these results could help improve space weather forecasting.

"I was not expecting what I found," Louis Seyfritz, a graduate researcher at the New Jersey Institute of Technology who led the new study, told Space.com.

Solar flares are powerful bursts of radiation from the sun driven by the sudden release of magnetic energy. The more powerful of these eruptions can disrupt radio communications, damage satellites and contribute to geomagnetic storms that affect infrastructure on Earth. Yet, despite decades of study, scientists still do not fully understand what causes these eruptions to occur.

Part of the challenge is practical. While spacecraft continuously monitor the sun, detailed observations of the conditions leading up to a flare are difficult to obtain. High-resolution instruments typically focus on active regions already producing solar activity, and researchers often begin tracking a flare in earnest only after it erupts — when it's possible to trace its path through space and assess its potential impacts on Earth.

In the new study, Seyfritz and his colleagues were able to take advantage of an unusually fortuitous dataset that captured the buildup to an X9-class solar flare that erupted on Oct. 3, 2024.

Their analysis identified several changes in the sun's atmosphere hours before the explosion, offering new clues about how major flares begin and potentially revealing early warning signs of future events.

The active region that produced the eruption had already generated several powerful flares in the preceding days, prompting scientists to keep multiple solar observatories focused on the area. Among them was NASA's Interface Region Imaging Spectrograph, or IRIS, a spacecraft designed to study a narrow slice of the sun's atmosphere in extraordinary detail.

And indeed, because IRIS was already observing the region, researchers obtained nearly five uninterrupted hours of observations before the flare erupted, providing a rare window into the processes unfolding in the sun's atmosphere before the explosion.

"I chose that event because I was expecting the flare to be big enough to see those signs," Seyfritz said. "There's very few that reach that amount of power."

Using data from IRIS, the researchers tracked three properties of plasma in the sun's atmosphere — its brightness, its motion toward or away from observers, and a quantity known as non-thermal velocity, a measure of turbulence and small-scale motions within the plasma. Together, those measurements allowed the team to reconstruct conditions in the hours before the flare, the study notes.

The results showed all three properties began increasing roughly three hours before the eruption, suggesting the sun's magnetic field was gradually becoming more unstable.

Such a long buildup of preflaring signatures is rarely observed, Seyfritz said.

The team also found that the plasma's brightness, motion and turbulence rose and fell in regular cycles before the flare. One repeated every seven to 10 minutes, while another appeared roughly every 18 to 21 minutes. The fluctuations were concentrated near a boundary where oppositely directed magnetic fields meet — a region where scientists suspect magnetic stress builds up before flares.

Scientists do not yet know exactly what causes the oscillations. They may reflect waves moving through the solar atmosphere or a series of small-scale magnetic reconnection events occurring before the larger eruption.

"If we see those oscillations happening before the flare, it can be a strong indicator that a flare is going to happen," Seyfritz told Space.com.

Roughly 15 to 20 minutes before the flare erupted, the sun's atmosphere appeared to shift into a more volatile state, with turbulence surging and plasma streaming outward — changes that may reflect the sudden release of magnetic energy that drives solar flares, the study notes.

No single measurement appeared to provide a definitive warning sign on its own. Instead, Seyfritz said, it was the combination of increasing brightness, rising turbulence and coordinated oscillations that stood out as a possible precursor signature.

To be clear, the findings do not immediately mean scientists can now predict solar flares hours in advance. The study examined a single eruption, and researchers do not yet know whether the same signatures appear consistently before other events. Answering that question will require analyzing many more flares — a challenge made difficult by the scarcity of suitable observations.

The next step, Seyfritz said, is to determine whether the same patterns emerge across a much larger sample of eruptions. If they do, the signatures could eventually become part of future space-weather forecasting systems.

"That's the goal," he said.

The results were published in May in the journal Solar Physics.

On August 12, 2026, a total solar eclipse will be visible in eastern Greenland, western Iceland and northern Spain. Eclipse chasers will travel to the path in droves, keen to witness a relatively short but ultimately dramatic totality. From Spain, eclipse chasers on the east coast will witness the rare spectacle on land of a totally eclipsed sun just a couple of degrees above the western horizon, minutes from sunset.

Read more: Total solar eclipse 2026 — Everything you need to know

What many eclipse chasers — and those unable to travel to the path of totality — may overlook is the massive partial solar eclipse visible across Europe. Across almost the entire continent, a huge chunk of the sun will appear eclipsed. Even rarer, a partially eclipsed sunset will be visible in France, Belgium, Germany, Poland, Estonia, Latvia, Lithuania, Belarus, Russia, Finland, Ukraine, Slovakia, Austria, Croatia, Hungary, Romania, Serbia, Italy, Kosovo, North Macedonia, and Albania. In Northwest Africa, a similar view awaits Morocco, Western Sahara, Mauritania, Algeria, Tunisia, Mali, Senegal, the Gambia, Guinea-Bissau, Guinea, Sierra Leone, Liberia, the Ivory Coast, and Burkina Faso.

This promises to be a mighty event that millions can view in some form — but do many know about it yet? Here's what you need to know about seeing a partial solar eclipse across Europe on Aug. 12, 2026.

How to read an eclipse map

The black line on the map above shows where the maximum partial eclipse will happen at sunset. In Warsaw, Poland, for example, the sun will be 83% eclipsed — the maximum there — as it sets. For locations just east of the black line, the sun sets before the partial eclipse ends. Just to the west, sunset occurs as the partial eclipse deepens.

So where should you be? For the best deep partial eclipse shots at sunset, position yourself west of the black line. Being on the line or just east of it will also work. It's less strict than the path of totality. Still, being close to the line on the northwest side is ideal.

Just remember that for all the focus on lines on a map, the spectacle itself — the deep partial eclipsed sunset — will take place on the horizon in the west-northwest.

"People living along the black sunset line will experience a beautiful deep partial eclipse at sunset," Michael Zeiler, eclipse cartographer, told Space.com. "Some ideal locations to see this over water are Algiers, Corsica, the Italian coast by the Ligurian Sea, and Venice, while High Alpine spots in eastern Austria will also have a dramatic sunset — a photographer's dream."

However, there are a few unexpected things to consider if you want the perfect view. "One interesting thing about these is that all the eclipse maps are calculating those lines for geometric sunset, which is when the middle of the sun is at the true horizon, ignoring refraction," Stephen Trainor at The Photographer's Ephemeris, told Space.com. "So what you tend to find is that actually the line isn't the line because refraction lifts the sun a little bit up — so you can usually creep a little bit the 'wrong' side of the line and you'll still be able to get the sun."

Best places to see the eclipsed sunset in Europe

Here are some places to be in Europe where you'll get views of a partially eclipsed sunset. At the selected sites, maximum obscuration occurs about 10-15 minutes before sunset. From Europe, the crescent sun will set "horns down" — a "sad face" (or upside-down "smiley face").

• Village d'Occi, Corsica, France (96% at 8:25 p.m. CEST, 24% chance of cloud, according to Timeanddate.com)
• La Spezia, Ligurian Sea, Italy (94% at 8:22 p.m. CEST, 43% chance of cloud)
• Modena, Italy (92% at 8:21 p.m. CEST, 38% chance of cloud)
• Venice, Italy (91% at 8:19 p.m. CEST, 43% chance of cloud)
• Kitzsteinhorn, Austria (89% at 8:16 p.m. CEST, 68% chance of cloud)
• Olympiaberg, Munich, Germany (88% at 8:15 p.m. CEST, 61% chance of cloud)
• Letná Park, Prague, Czechia (86% at 8:11 p.m. CEST, 65% chance of cloud)
• Ostrów Tumski, Wrocław, Poland (84% at 8:09 p.m. CEST, 66% chance of cloud)

• Lilastes pludmale, Gulf of Riga, Latvia (80% at 8:57 p.m. EEST, 63% chance of cloud)

Best places to see the eclipsed sunset in Africa

Here are some great places to be in northwest Africa, where you'll get views of a partially eclipsed sunset. Selected sites will experience maximum obscuration no more than 30 minutes before sunset (the sunset line largely passes through the remote Sahara Desert). From Africa, the crescent will slip beneath the horizon in the shape of the letter "C."

• Cape Matifou, Tamentfoust, Algeria (98.5% at 7:42 p.m. CET, 49% chance of cloud)
• Essaouira, Morocco (81% at 7:47 p.m. WEST, 15% chance of cloud)
• Dakar, Senegal (37% at 7:12 p.m. GMT, 82% chance of cloud)
• Banjul, Gambia (34% at 7:13 p.m. GMT, 80% chance of cloud)

Best places to see the eclipsed sunset in Spain

On Aug. 12, mainland Spain will host a path of totality for the first time since 1905. The path, about 182 miles (293 km) wide, will just miss Barcelona and Madrid. Some eclipse chasers will focus on seeing a totally eclipsed sun a few degrees above the horizon — minutes from sunset — from the Balearic Islands (Mallorca, Ibiza, Menorca, and Formentera). That will be spectacular if the horizon is clear. But what some may overlook is this: in some areas, a partially eclipsed sunset will follow totality.

Watch the eclipse from Spain's Meseta region — including Burgos and León — and you'll see totality, followed by a partial eclipse that finishes minutes before sunset. In Soria, Sigüenza, Zaragoza, Teruel, and farther east toward the coast, you'll see totality and then a partially eclipsed sunset. The farther east you are, the more eclipsed the sun will be as it sinks into the horizon.

Planning a trip to see the eclipsed sunset?

An unobstructed, low western horizon is essential. So are clear skies because even distant clouds can block the view of sunset. For the horizon, try this tip: search for "sunset spots near [location] in August" to find recommendations from locals and tourists. However, as Trainor says, "go out and scout the location two or three nights before so you can develop an alternative if it's not going to pan out on the ground." He also advises using both his precision planning tool, which helps photographers visualize the sun, moon, and natural light, and a "sanity check" on Google Street View, just to prove that a shot is possible.

For the weather, patience is required — all you can do is check forecasts three days before Aug. 12, when predictions become fairly reliable. However, predicting low clouds along the horizon is tough. You'll need clear weather for many hundreds of miles to the west-northwest.

An annular solar eclipse will occur on Feb. 6, 2027, when the moon's cone-shaped central shadow will not quite reach Earth. The result will be a 'ring of fire' visible to those within a broad path across southern Chile, Argentina and coastal parts of West Africa.

At the point of greatest eclipse in the Pacific, the moon will cover 93% of the sun's disk, leaving a relatively large bright ring visible for 7 minutes and 51 seconds. That makes it one of the longest annular solar eclipses this decade.

During an annular solar eclipse, it is NEVER safe to look directly at the sun without solar eclipse glasses designed for solar viewing. Read our guide on how to observe the sun safely.

This annular solar eclipse has a long and broad path, rising southwest of Easter Island (Rapa Nui) in the south Pacific Ocean and setting in the Gulf of Guinea, West Africa.

That journey is 9,011 miles (14,501 kilometers), with the path between 180-220 miles (289-355 km) wide. The path of annularity crosses southern parts of Chile, Argentina, Uruguay and (a tiny sliver of) Brazil in South America. After crossing the Atlantic, the northern edge of the path just makes land in the Côte d'Ivoire, Ghana, Togo, Benin and Nigeria.

The Path of Annularity: South America

Eclipse chasers wanting to observe annularity high in the sky while on land should head to Chile or Argentina, with the latter having a better chance of a clear sky. The path crosses northern Patagonia, a region of wide skies, low population, and — crucially in February — a generally favorable climate.

As it reaches Chile's Pacific coast, the "ring of fire" will sit around 50° above the northeast, but this region of mountains and fjords is both logistically challenging and likely cloudy. Average February cloud cover along the centerline in Chile is typically around 65%, while just across the mountains in a classic rain-shadow zone in Argentina's Patagonian plains, cloud cover drops to as low as 30%, according to meteorologist Jay Anderson on Eclipsophile.com.

Standout locations in the rain-shadow include El Maitén (which is being favored by eclipse tour groups), Esquel and Trevelin, where annularity occurs just before midday. There's a similarly small chance of cloud on Argentina's Atlantic coast, with potential observing locations including Las Grutas on the San Matias Gulf and, south of Buenos Aires, the lush Laguna La Brava.

Although the path brushes Uruguay (just missing Montevideo), and nicks Brazil (just missing Rio de Janeiro), once the centerline of the path of annularity leaves Argentina, it doesn't make landfall again.

The Path of Annularity: Africa

After crossing the South Atlantic, the path of annularity makes its final landfall in West Africa, reaching Côte d'Ivoire, Ghana, Togo, Benin and Nigeria.

Here, the eclipse unfolds late in the day, with the "ring of fire" hanging low in the western sky as it approaches the horizon. At Abidjan, Côte d'Ivoire, the sun will be 7.7° above west-southwest just 30 minutes before sunset, though a potentially orange-golden "ring of fire" will last for just a fleeting moment. Other potential observing locations include Cape of Three Points in Ghana for a long annular phase just six degrees above the horizon, as well as the capital city, Accra, where it's just four degrees up. Lomé in Togo, Cotonou in Benin and Lagos in Nigeria will see the annular phase moments before sunset.

Although statistics show cumulus cloud cover in this region to be common, much of it dissipates by late afternoon, according to Anderson, with sea-breeze winds from the Atlantic — as well as "eclipse cooling" — potentially helping. As such, there's around a 90% chance of a clear sky in this region for a spectacular sunset "ring of fire." A much bigger problem, however, could come from Saharan dust, with reduced clarity likely.

Why does the 2027 'ring of fire' last so long?

The Feb. 6, 2027 annular solar eclipse is unusually long, with its maximum phase lasting up to 7 minutes 51 seconds just off the coast of Brazil — far longer than most annular eclipses, and significantly longer than the totality phase during a total solar eclipse.

The reason is geometry. Annular eclipses happen when the moon is near apogee, its farthest point from Earth, making it appear slightly too small to cover the sun. Instead of a brief blackout, the moon takes longer to cross the sun's face, leaving a bright ring visible throughout. The moon reaches apogee three days before Feb. 6, 2027.

That duration is extended because Earth is near perihelion in early January, when the sun appears marginally larger than average. A smaller apparent moon and a larger apparent sun combine to lengthen the event.

Even so, 2027 is not a record-breaker. Under a near-perfect alignment, annularity can theoretically last up to about 12 minutes and 29 seconds. The longest this century occurred on Jan. 15, 2010, when the ring of fire persisted for just over 11 minutes.

An incoming coronal mass ejection (CME) is expected to slam into Earth's magnetic field today (June 8), potentially triggering geomagnetic storm conditions strong enough to supercharge auroras into mid-latitudes.

The CME erupted from the sun on June 6 and is forecast to arrive early to midday GMT on June 8. Space weather forecasters from NOAA's Space Weather Prediction Center and the U.K. Met Office suggest the impact could spark minor to moderate (G1 to G2) geomagnetic storm conditions initially, possibly ramping up to strong (G3) levels later in the day.

As such, NOAA has issued a G3 geomagnetic storm watch for June 8 and a G2 watch for June 9 as forecasters monitor the solar storm's approach. This is great news for aurora chasers.

When can I see the northern lights tonight?

The northern lights could become active at various times throughout June 8 as the incoming CME arrives.

The strongest storm conditions are currently expected between 11 a.m. and 2 p.m. EDT (1500-1800 GMT), when a strong (G3) geomagnetic storm is possible. While a daytime peak is far from ideal for North American aurora chasers, it doesn't necessarily rule out a nighttime display. NOAA's Space Weather Prediction Center forecasts geomagnetic activity to remain elevated through the evening, with G2 conditions possible between 5 p.m. and 8 p.m. EDT (2100-0000 GMT), before gradually easing overnight.

It's also worth remembering that CME arrival times can shift by several hours. If the solar storm arrives later in the forecast, the strongest geomagnetic activity could occur closer to — or even after — sunset for parts of North America, drastically improving viewing opportunities.

Will the northern lights be visible from where I live?

If the incoming CME triggers a strong (G3) geomagnetic storm, the northern lights could become visible much farther south than usual.

According to NOAA's geomagnetic storm scale, auroras may be visible as far south as:

• G1 (minor): Northern Michigan and Maine
• G2 (moderate): New York and Idaho
• G3 (strong): Illinois and Oregon

But remember, even during strong geomagnetic storms, aurora visibility is never guaranteed. Cloud cover, local light pollution and the orientation of the CME's magnetic field when it reaches Earth can all influence aurora visibility.

For the best chance of seeing the northern lights, head to a dark location with a clear view of the northern horizon and allow your eyes time to adjust to the darkness. If the aurora is faint, a smartphone camera can often reveal colors and structures that are difficult to see with the naked eye, during weaker displays.

For real-time forecasts based on your location, consider using a space weather app. A great option is "My Aurora Forecast & Alerts" (available for iOS and Android). For a deeper dive into space weather conditions, "Space Weather Live" is another excellent choice (available for iOS and Android)

Beaches offer wide-open spaces and low-horizon views, making them ideal for skywatching. For the Aug. 12, 2026, total solar eclipse, Spain's beaches will be among the most sought-after locations — but not all will deliver. The path of totality crosses the north and east of the country just before sunset, with the sun low in the west-northwest. Many top resorts face east for sunrise views, so at the crucial moment, the sun may be blocked by hotels or terrain behind you.

To experience totality — the brief period during a solar eclipse when the sun is completely covered by the moon — clearly, being on the coast isn't enough — you need a clear, unobstructed view to the west-northwest, ideally over open water. That's why the best eclipse beaches are either on Spain's Atlantic-facing north coast, where the horizon is open, or in carefully chosen Mediterranean spots where development is low, and sightlines are clean.

The altitude of the eclipsed sun matters: in Galicia, Asturias, and the Cantabrian Coast, it's 12 to 9 degrees above the horizon — manageable but low. On the Mediterranean and Balearic Islands, it's just 4 to 2 degrees, turning totality into a fleeting event easily obscured by haze or thin cloud.

Choose your beach wisely (checking tide times a few weeks in advance on Surf Forecast or Tide Forecast), and you'll watch the moon's shadow race in from the Atlantic before revealing the corona during totality, just minutes before sunset.

Get it wrong, and you could miss everything.

Essential resources for checking and re-checking intended destinations for totality include Xavier Jubier's Interactive Google Map, which has timings and built-in sightlines from Peak Finder, as well as The Eclipse App, Eclipse Horizon Checker and the Instituto Geográfico Nacional. The best advice is to test your location the day before the eclipse. Let's look at some of the best beaches in Spain for eclipse viewing, complete with details on timing and conditions.
