3D-printed rocket ready for another launch attempt
Wednesday, March 22, 2023: The 3D-printed Terran 1 rocket made by California-based company Relativity Space is waiting on a launchpad in Cape Canaveral ahead of its next debut launch attempt.
The launch attempt, the rocket's third, is planned to take place on Wednesday (March 22) during a three-hour window that opens at 10 p.m. EDT (0200 GMT on March 23). Relativity Space has previously scrubbed two launch attempts, one because of fuel-temperature issues, the second because of bad weather. – Tereza Pultarova
NASA rocket that will send humans to the moon next year is coming together
Tuesday, March 21, 2023: The 212-foot-tall (65 meters) core stage of NASA's Space Launch System (SLS) rocket that will send the first human crew since the Apollo era to the moon next year has been put together at the Michoud Assembly Facility in New Orleans.
Over the past few weeks, NASA and Boeing engineers joined together the rocket's five main structures. On Friday, March 17, the team completed the work by attaching the engine section and is now preparing to integrate the stage's four RS-25 engines, NASA said in a statement (opens in new tab).
The rocket will launch the Artemis II mission with four astronauts for a lunar roundtrip in 2024. The mission paves the way for NASA's ambitious plans to establish permanent human presence on the moon and in the moon's orbit. – Tereza Pultarova
Earth on equinox
Monday, March 20, 2023: Spring has officially begun in the Northern Hemisphere today with Earth reaching the equinox. And the European weather forecasting satellite Meteosat-10 captured the moment from space.
Equinox happens twice a year, in September and March, and marks the moment when the Earth's tilted axis is perfectly perpendicular to the imaginary line between our planet and the sun. On equinoxes, both Earth's hemispheres receive the same amount of light during the day, which lasts all over the world about 12 hours.
The Meteosat image shows the so-called terminator line, the line separating day and night, which on the equinox leads directly from north to south. Meteosat took this image at 2:00 a.m. ET (0600 GMT), just as day was breaking over Europe.
The exact moment of the equinox, however, will take place at 5:24 p.m. ET (2124 GMT) today. From that moment on, the Earth's axis will start tilting again. The Northern Hemisphere will be receiving more daylight than the Southern Hemisphere. The length of the day in the north will continue increasing until the summer solstice in June when the Northern Hemisphere will experience its longest day and shortest night of the year. – Tereza Pultarova
Hubble sees newborn stars in tiny galaxy
Friday, March 17, 2023: A tiny diffuse galaxy known as UGCA 307 can be seen on the right hand side of this Hubble Space Telescope image as a hazy red-speckled cloud of stars.
The Hubble Space Telescope took this image as part of a survey studying the galactic neighborhood of our galaxy, the Milky Way. UGCA 307 is a dwarf galaxy located 26 million light-years away from Earth in the constellation Corvus in the southern sky.
The galaxy has no defined structure and consists only of a diffuse band of stars with red bubbles of gas contained within, revealing areas of recent star formation.
Hubble took this image using its Advanced Camera for Surveys (ACS), which was installed on the telescope during a 2002 servicing mission. The European Space Agency, which co-funds the Hubble Space Telescope's operations, released the image (opens in new tab) on Friday, March 17. – Tereza Pultarova
New map reveals distribution of water on the moon
Thursday, March 16, 2023: A new map reveals water distribution on the moon's surface in best-ever detail.
The map, based on measurements taken by the now retired NASA's air-borne telescope SOFIA, provides hints how water may be moving across the moon's surface, NASA said in a statement (opens in new tab).
The new map is the first to capture a wide area around the moon's south pole, which is an important target of future exploration, in such detail.
The map covers about one quarter of the Earth-facing side of the lunar surface below 60 degrees latitude and extends all the way to the south pole, NASA said in the statement.
This wide coverage enables scientists to see how individual geological features influence water distribution on the surface. – Tereza Pultarova
Falcon 9 shoots off toward the space station
Wednesday, March 15, 2023: SpaceX's Falcon 9 rocket blasting off from Florida with a Cargo Dragon capsule atop, heading to the International Space Station.
The rocket lifted off from Cape Canaveral Space Force Station in Florida at 8:30 p.m. EDT on Tuesday, March 14, (0030 GMT on March 15) sending SpaceX's 27th contracted cargo mission to the orbital outpost. The capsule, carrying supplies and scientific experiments, is scheduled to reach the space station on Thursday (March 16) at 7:52 a.m. EDT (1152 GMT). – Tereza Pultarova
Great Lakes winter ice cover at record low, satellites reveal
Tuesday, March 14, 2023: The Great Lakes between the U.S. and Canada appear nearly ice-free in this image captured by the European Earth-observing satellite Sentinel-3 on March 8 after an unusually warm winter that led to a record-low ice-cover.
According to the U.S. National Oceanic and Atmospheric Administration (opens in new tab) (NOAA), only 7% of the Great Lakes' surface was covered with ice in the winter of 2022 and 2023. This value is considerably lower than the average 35 to 40% ice cover extent recorded in the years since 1973.
In a statement issued on February 17, NOAA said that data collected over the past 44 years shows a clear declining trend in the Great Lakes' winter ice cover. This year's February scored a record low, owing mostly to warmer than usual temperatures, NOAA said. – Tereza Pultarova
An orbital sunset above the Atlantic Ocean
Monday, March 13, 2023: This image shows the moment of sunset above the Atlantic Ocean captured from aboard the International Space Station.
The station orbits at the altitude of 264 miles (425 kilometers) and circles Earth every 90 minutes. Astronauts on board the space lab therefore get views of 16 sunsets and 16 sunrises every day. This time, the space station crossed the so-called terminator line, the line separating day from night as experienced on Earth off the coast of southwestern Africa. – Tereza Pultarova
Friday, March 10, 2023: A Japanese weather satellite took this stunning image of the moon emerging above Canada on Wednesday, March. 9.
The image was taken by the Himawari-9 weather forecasting satellite that observes Earth from geostationary orbit, the sweet spot at the altitude of about 22,000 miles (36,000 kilometers), where satellites appear suspended above a fixed spot on the planet's equator.
The image was processed and shared on Twitter by Earth-observation scientists Simon Proud of the U.K.'s National Centre for Earth Observation. – Tereza Pultarova
Near-record snowfall promises to alleviate California's drought
Thursday, March 9, 2023: The amount of water in California's largest reservoir, Lake Shasta, has doubled since last October, thanks to abundant rain and snowfall that promise to alleviate the state's severe drought problem.
This GIF consists of two images capturing the area around Lake Shasta, which were taken by Earth-observing satellites of the U.S. company Planet in October, 2022, and in March this year.
In October, the lake held 61.6 billion cubic feet (1.7 billion cubic meters) of water. Thanks to a series of powerful storms that have drenched California in the past months, the amount of water in the lake has risen to 120 billion cubic feet (3,4 billion cubic meters) by early March.
The image also shows the surrounding landscape covered in snow, the amount of which has been described as near record level. Once the snow melt season starts this spring, the amount of water in the lake will rise even further.
Water from melting snow is also more likely to increase soil moisture as it's released gradually and has a better chance of soaking into the ground compared to fast-moving rain water, Planet said in a statement (opens in new tab). – Tereza Pultarova
Cyclone Freddy ravages Madagascar
Wednesday, March 8, 2023: European Earth-observing satellite Sentinel-3 captured this image of tropical cyclone Freddy that is currently ravaging Madagascar, having killed over 21 residents so far and forcing thousands to leave their homes.
The cyclone formed over a month ago above the Indian Ocean and is now set to become the longest lasting cyclone in history, according to CNN (opens in new tab).
The World Meteorological Organization described Freddy as a "very rare" and "incredibly dangerous" storm. The area of low air pressure, which gave rise to Freddy, emerged on Feb. 6 off the coast of Australia. The storm then tracked thousands of miles westwards and hit the tropical island of Madagascar for the first time on Feb. 21. The storm then continued to the coast of east Africa, where it made landfall in Mozambique, causing widespread destruction. The cyclone then bounced back to Madagascar and is now expected to loop once again to Mozambique, intensifying as it moves above the warm waters of the Indian Ocean.
The current record holder for the longest-lasting cyclone is Typhoon John, which kept stirring the Pacific waters for 31 days in 1994. Unlike Freddy, Typhoon John, didn't make landfall and only skirted Hawaii, where it caused minor damage. – Tereza Pultarova
3D-printed rocket awaits debut flight
Tuesday, March 7, 2023: The 3D-printed Terran 1 rocket made by California-based Relativity Space is sitting on its launchpad ahead of its debut launch attempt that is scheduled for Wednesday, March 8.
If all goes to plan, the 110-foot-tall (33.5 meters), 7.5-foot-wide (2.9 m) rocket will lift off from Cape Canaveral Space Force Station on Florida's space coast shortly after 1 p.m ET (1800 GMT) on Wednesday. The launch will be the first not only for Terran 1 but for Relativity Space as a company and will carry no customer payload.
The company says that Terran 1 will be the largest 3D-printed object ever to attempt orbital flight. The rocket's nine 3D-printed engines use liquid oxygen and liquid natural gas, which the company says is "best for reusability." – Tereza Pultarova
Curiosity captures twilight sun rays on Mars
Monday, March 6, 2023: NASA's veteran Mars explorer Curiosity captured this image of twilight sun rays penetrating through a veil of clouds shrouding the Red Planet last month.
The image, taken by Curiosity's Mast Camera, or Mastcam, shows the sun descending below the horizon on Feb. 2, while its rays scatter off a bank of clouds.
According to a NASA statement, this photo captures the first occasion when the "sun rays have been so clearly viewed on Mars."
Curiosity captured the scene as it embarked on the latest round of its cloud survey, which builds on its 2021 observations of noctilucent, or night-shining, clouds. While most Martian clouds hover no more than 37 miles (60 kilometers) above the ground and are composed of water ice, the clouds in the latest images appear to be at a higher altitude, where it’s especially cold. That suggests these clouds are made of carbon dioxide ice, or dry ice, NASA said in the statement. – Tereza Pultarova
Full house on International Space Station
Friday, March 2, 2023: The number of International Space Station occupants has risen to 11 after the arrival of Crew-6 aboard SpaceX's Dragon Endeavour capsule on Friday (March, 3).
The four new crew members (in their blue overalls) pose in the middle of this image with the current seven members of Expedition 68, which includes four space travelers from SpaceX's previous Crew-5 mission and three spacefarers who arrived on Russia's Soyuz M-22 (the one that experienced a fatal coolant leak in December last year).
The new arrivals are, left to right, United Arab Emirates astronaut Sultan Alneyadi, NASA's Steven Bowen, Roscosmos cosmonaut Andrey Fedyaev and NASA's Woody Hoburg.
Crew-6 will replace Crew-5 astronauts Nicole Mann and Josh Cassade of NASA, Japan's Koichi Wakata and Russia's Anna Kikina, who are expected to depart for Earth in the middle of next week. – Tereza Pultarova
SpaceX's Falcon 9 rocket with crewed Dragon capsule atop heads to space station
Thursday, March 2, 2023: SpaceX's Falcon 9 rocket can be seen in this image shortly after its liftoff from NASA's Kennedy Space Center in Florida on Thursday, March 2. Atop the rocket is a crewed Dragon capsule with four spacefarers of the Crew 6 mission heading to the International Space Station.
The mission, SpaceX's seventh taking astronauts to the orbital outpost (including the demonstration flight in May 2020), launched at 12:34 a.m. ET (1234 GMT) today and is scheduled to dock with the station's Harmony module on Friday, March 3, at about 1:17 a.m. ET (617 GMT).
Aboard the capsule, called Endeavour after the namesake space shuttle mission, are NASA astronauts Stephen Bowen and Woody Hoburg, Russian cosmonaut Andrey Fedyaev and United Arab Emirates' (UAE) space traveler Sultan Al Neyadi, who will be the first UAE national to carry out a six-month mission on the International Space Station. – Tereza Pultarova
Auroral glow surprises astrophotographer in California's Death Valley
Wednesday, March 1, 2023: An American stargazer has caught an unexpected glimpse of aurora during an astrophotography trip to California's Death Valley.
The sighting, documented in this beautiful image that shows the arch of the Milky Way above a purple glowing horizon, may be the southernmost of the aurora spree delivered by a strong solar storm in the last two days of February.
"I was indeed shocked to see this," Shari Hunt, the author of the image, who is a medical researcher and part-time astrophotography tutor, told Space.com in an email. "I was there in Death Valley for night photography and with the storm in California, we had clouds almost every morning blocking the galactic core. This was our last morning to shoot."
At 36 degrees northern latitude, Death Valley is too far south for most aurora displays. Polar lights usually remain contained around polar circles and occasionally spread to higher parts of mid-latitudes. But despite the intense space weather conditions forecasted for Feb. 28, the spectacle wasn't expected to reach all the way to California.
Hunt first noticed the strange glow when she directed her camera to the north after setting up her gear at the popular Mesquite Flat Sand Dunes. In fact, the glow was so unexpected that she first thought she must have made a mistake.
"I thought I left my camera on auto white balance or something went wrong," Hunt recalled. "I had never seen an airglow like that! So, I took another shot and told my friend who was also there to check with her camera."
The two took repeated shots, all of which revealed the eerie glow that was gradually giving way to light pollution above Las Vegas on the right hand side of the image. The single sharp spot of light in the image is a car that accidentally appeared on a local road, Hunt said.
"After looking in post and seeing the changing or dancing, I knew we had captured the aurora," said Hunt. "We checked the aurora forecast as well, which also helped confirm it!"
Hunt shot the image with a Sony A7R III camera using a f/2.8 lens, 25 second-exposure and ISO 6400 sensitivity.

Weather satellite spots auroras dancing above the pole
Tuesday, February 28, 2023: Auroras that set the sky ablaze across northern and central Europe and North America in the last two days were so intense that they could be seen from space by weather-forecasting satellites.
In this image, taken by the U.S. National Oceanic and Atmospheric Administration's (NOAA) namesake satellite NOAA-20, the recent aurora borealis displays can be seen as a band of orange-tinted glow that crosses the Atlantic Ocean above the British Isles and spills over into Scandinavia.
NOAA-20, which orbits 512 miles (824 kilometers) above Earth's surface, took the image on Sunday (Feb. 26) at 11:01 p.m. ET (0401 GMT on Monday, Feb. 27). The image was processed by scientists at the Cooperative Institute for Research in the Atmosphere (CIRA) in Colorado and was shared on Twitter by a user called @ar_etsch.
Simon Proud, an Earth-observation scientist at the National Centre for Earth Observation in the U.K. explained in a comment that NOAA-20 was able to detect the aurora as it "has a special low light band, which picks up anthropogenic lights and also things like aurora." – Tereza Pultarova
Auroras set sky ablaze all over the British Isles
Monday, February 27, 2023: Powerful solar wind is blowing from the sun these days, setting the sky ablaze with auroras all over the British Isles. This particular picture was taken by an astrophotographer in Northern Ireland.
Stunning aurora borealis displays have been reported on the night from Sunday, Feb. 26, to Monday, Feb. 27, from all over the U.K., even from as far south as the iconic Stonehenge monument (opens in new tab) in Wiltshire
Stunned skywatchers took to Twitter in droves to share their catches, with reports of aurora sightings pouring in from Scotland, northern Wales, Ireland and southern England.
Northern Irish photographer Evan Boyce experienced a memorable night of aurora chasing, which, despite being his first polar lights adventure, produced some stunning results.
"I first picked up a camera during the COVID lockdown and have wanted to capture the aurora ever since," Boyce told Space.com in an email. "It's quite difficult living in Northern Ireland, given how far south we are in comparison to where the aurora can normally be viewed."
He added that all his earlier attempts at aurora chasing were ruined by cloudy weather. On Sunday night, Boyce drove to a beach between the towns of Bangor and Donaghadee, a short drive from Northern Ireland's capital Belfast. There he captured an eerie green and red glow above a historical building with a backdrop of a star-studded sky.
"I can't believe how lucky I've been," Boyce said. "Judging by the reaction from other local photographers, the strength & colors last night were a rare event."
According to the U.K. space weather forecaster Met Office (opens in new tab), the spectacle was a result of two solar physics phenomena occurring at the same time. There is currently a so-called coronal hole opened in the sun's magnetic field, from which streams of solar wind emanate at higher than usual speeds. In addition to that, a coronal mass ejection (CME), a powerful burst of solar wind from an active region, or sunspot, erupted from the sun on Friday, Feb. 24, and arrived last night. – Tereza Pultarova
Artemis 2 moon rocket coming together
Friday, February 24, 2023: NASA is assembling the Space Launch System rocket that will launch the Artemis 2 mission to the moon as early as next year, taking the first humans since the final Apollo flight in the 1970s to the moon's orbit.
"Engine section, meet the rest of the core stage," NASA said in a Tweet (opens in new tab) shared via the Marshall Space Flight Center account on Friday (Feb. 24). "Teams at #NASAMichoud have lined up the engine section with the rest of the @NASA_SLS core stage for Artemis II. Next up, joining the two sections."
NASA completed the Space Launch System's debut launch with the uncrewed Artemis 1 test-flight in November last year with flying colors. The stakes are, however, getting higher with Artemis 2, which will pave the way for NASA's ambitious plans to establish permanent human presence on the moon and in its orbit. – Tereza Pultarova
Crescent moon meets Jupiter and Venus in the sky above New Jersey
Thursday, February 23, 2023: The crescent moon rises in the early evening sky accompanied by Jupiter and Venus in this image taken by an astrophotographer in New Jersey.
The celestial encounter is a so-called conjunction, a situation when celestial bodies temporarily meet in the same area of the sky. The conjunction between the two-day-old waxing crescent moon and the two other brightest objects in the sky, planets Venus and Jupiter, took place on Wednesday (Feb. 22).
Audrey Geddes of New Jersey took this image of the celestial encounter over a remote region of the Pine Barrens during the evening twilight.
"To get to this remote area, you have to drive down sand roads through a pitch pine forest," Geddes told Space.com. "Excellent location for astrophotography and observing the stars. The only thing that made it challenging to photograph were the clouds."
Geddes took the picture on a NIKON D7500 camera with a 3.8 aperture lens using an 8-second exposure and ISO 400 sensitivity. – Tereza Pultarova
James Webb Space Telescope peers inside Milky Way's oldest star cluster
Wednesday, February 22, 2023: The James Webb Space Telescope has looked inside one of the oldest components of our Milky Way galaxy, the Messier 92 globular cluster located some 27,000 light-years away from Earth.
The James Webb Space Telescope, or Webb, observed the globular cluster, also known under the shortcut M92, early after coming online. It took only one hour to capture the sparkling image above, according to a statement (opens in new tab) by the Space Telescope Science Institute, which operates the observatory.
Primarily built to study the most distant objects in the far-away reaches of the universe, Webb easily detected the multitude of stars inhabiting the cluster, including the dim and cool ones that were invisible to its predecessor, the Hubble Space Telescope. Some of the stars in this image are tiny, only 0.1 the mass of our sun, Roger Cohen, an astronomer at Rutgers University and one of the scientists behind the observations, said in the statement.
"This is very close to the boundary where stars stop being stars," Cohen said. "Below this boundary are brown dwarfs, which are so low-mass that they're not able to ignite hydrogen in their cores."
The image, captured by Webb's Near Infrared Camera (NIRCam), reveals only a small portion of the M92 cluster. The whole cluster, about 100 light-years wide, has 300,000 stars squeezed inside of it. If an inhabited planet like Earth were to orbit one of those stars, the creatures on its surface would have a magnificent view of the night sky, which would shine with thousands of stars that would be thousands of times brighter than those humans can see from Earth.
M92 is one of the oldest globular clusters in the Milky Way, consisting of stars that formed 12 to 13 billion years ago, when the universe was only a few hundreds of thousands of years old. – Tereza Pultarova
Cubesat that launched to the moon on Artemis 1 sees green comet
Tuesday, February 21, 2023: Japan's cubesat EQUULEUS, which hitched a ride to the moon aboard NASA's Artemis 1 mission in November last year, took a video of Comet C/2022 E3 (ZTF) earlier this month, about two weeks after the ice ball's closest approach to Earth.
The comet — also called the green comet for its hue or the Neanderthal comet, as it hasn't visited Earth since the era of the Neanderthals — can be seen in the video sequence shared on Twitter as a fuzzy white dot traversing a star-studded black-and-white background.
"EQUULEUS successfully photographed Comet ZTF (Comet C/2022 E3) from space!" the EQUULEUS team said in a tweet accompanying the image sequence shared on Tuesday (Feb. 21).
The 6U cubesat , built by the Japanese Aerospace Exploration Agency (JAXA) and the University of Tokyo, imaged the comet for six hours on Feb. 12. At that time, the cubesat was about 43 million miles (69.5 million kilometers) from the comet and 211,000 miles (340,000 km) from Earth. – Tereza Pultarova
Satellites reveal devastation in Turkey's city of Antakya
Monday, February 20, 2023: The destruction of the Turkish city of Antakya caused by the devastating earthquake on Feb. 6 is revealed in a series of images taken by the European Earth-observing satellite Sentinel-2.
The first image in this sequence shows Antakya on Jan. 25, nearly two weeks before the disaster, which has killed at least 46,000 people. The second image captures the situation on Feb. 14 with thousands of buildings destroyed. – Tereza Pultarova
Rare red auroras explode over northern Europe and Canada
Friday, February 17, 2023: A stream of solar plasma arrived at Earth last night, supercharging the atmosphere with particles from the solar wind that triggered rare red aurora displays across vast portions of Canada, northern U.S. and Europe. And space weather forecasters promise that more is on its way.
Twitter has been virtually awash over the past days with skywatchers' images and accounts of spectacular aurora sightings. The latest wave of dancing polar lights has been especially striking, as it arrived in rare shades of red that require higher concentrations of solar wind particles to penetrate deeper into Earth's atmosphere.
Quebec, Canada-based aurora hunter Mike MacLellan shared with Space.com his catches: out of this world photographs of the horizon ablaze with bright neon-like green that turns into orange, red and purple higher up in the sky. Similar red aurora sightings have been reported by photographers in Scotland and Norway.
The aurora overload is expected to continue and possibly get even more impressive as a coronal mass ejection (CME), a burst of plasma from the sun's upper atmosphere that erupted from the sun Feb. 15 is arriving at Earth today.
Aurora sightings as far south as the north of England and the U.S. can be expected. The geomagnetic storming is expected to carry on until at least Feb. 19, so if you have an opportunity, head north for the weekend to make the most of it. – Tereza Pultarova
Rose-like nebula shines bright on star-studded sky in an astrophotographer's image
Thursday, February 16, 2023: The Rosette Nebula in the constellation Unicorn shines bright in the star-studded sky in a photo captured ahead of this year's Valentine's Day by an Arizona-based astrophotographer.
The spectacular nebula is located 5,200 light-years away from Earth and you can find it to the left of Betelgeuse, the second brightest star in the constellation Orion.
Hot young stars in the nebula produce energetic atoms in their cores, which then feed the cloud of hydrogen gas that forms the nebula.
Astrophotographer and NASA astronomy ambassador Mark Johnston took the image from Rio Verde in Arizona on Feb. 11 using a Celestron C9.25 SCT telescope and a ZWO2600 astrophotography camera. He created the image by stacking 256 60-second exposures. For more of Johnston's astrophotography, visit his website at www.azastroguy.com. – Tereza Pultarova
Valentine's Day auroras shine bright over Alaska
Wednesday, February 15, 2023: The spectacular aurora display over Alaska delivered on Valentine's Day by a well-timed solar eruption got one experienced aurora hunter extremely excited.
Vincent Ledvina is no stranger to the sight of glimmering polar lights. Based in Fairbanks, Alaska, the space physics PhD student, took his first aurora picture aged 16. Since then, he says on his website (opens in new tab), he's been hooked on the thrill of aurora chasing. This passion eventually led to him relocating from North Dakota to Alaska, the northernmost U.S. state that straddles the northern polar circle and offers the best conditions for aurora watching.
Vincent's Twitter account and his website's photo gallery are overflowing with stunning aurora pictures. Yet, in a series of excited tweets shared on Feb. 14, he admitted that this year's Valentine's Day auroras were out of the ordinary.
"Everything about tonight was insane," Ledvina said in a Tweet (opens in new tab) shared in real time as his aurora party drew to a close. "One of the best nights of aurora of my life, maybe the best. We had substorm after substorm, it never let up."
In another tweet (opens in new tab), he called the experience "straight up magic." In yet another (opens in new tab), accompanied by an image of a shimmering ribbon of green and purplish glow suspended above the wintery landscape, he confessed that he had never seen such intense shades of red in an aurora.
Just head to Ledvina's Twitter page to get the feel of that night.
"That was freaking incredible. INSANE substorm. The whole sky is glowing, so cool, no other words. Wow!!!!," Ledvina said in yet another post (opens in new tab). – Tereza Pultarova
Turkey earthquake destruction laid bare in new satellite images
Tuesday, February 14, 2023: New images from the U.S. Earth observation company Maxar reveal the scope of destruction in cities and towns across Turkey in the wake of two devastating earthquakes that struck the region last week.
This image, taken on Monday (Feb. 13), shows collapsed buildings in the city of Kahramanmaras, about 100 miles northeast of the Mediterranean coast. Kahramanmaras is one of the hardest hit areas as it lies closest to the epicenter of the deadly 7.8 Richter scale magnitude temblor that shook the region last Monday (Feb. 6) in the early morning hours.
"Extensive building damage with debris removal operations in process can be seen, along with temporary shelters in the area," Maxar Technologies said in a tweet (opens in new tab) accompanying the image.
More than 36,000 victims have been pulled out from rubble in the region around the Turkish-Syrian border. In Kahramanmaras alone, 600 people perished in the ruins. On the Syrian territory, rescue operations are proceeding especially slowly as the country has been mostly isolated for years due to a years-long civil war. – Tereza Pultarova
Astronomer discovers tiny asteroid shortly before it hits Earth
Monday, February 13, 2023: This is the first photo of a 3-foot-wide (1 meter) asteroid that burned up in Earth's atmosphere only a few hours after it was discovered.
The space rock was discovered by Hungarian astronomer Krisztián Sárneczky during a routine "near-Earth asteroid hunt" on Sunday (Feb. 12). Sárneczky, who is one of the world's most prolific asteroid hunters, first spotted the rock at about 10 pm local time and at first had no clue he was looking at an Earth-bound rock.
"At that time, the calculations did not show that it was an imminent impactor," Sárneczky told Space.com in an email. "It wasn't going fast across the sky at all, as it was heading right towards us, and it was faint. It was only when I observed it again half an hour later and measured its coordinates that the calculations showed that it was coming towards Earth."
A measurement made by astronomers in Croatia confirmed that the previously unknown asteroid was on a collision course with Earth. The rock, named Sar 2667 in Sárneczky's honor, indeed, dove into Earth's atmosphere about four hours after its discovery and burned up above the English Channel between France and the U.K., producing a spectacular fireball that was captured by many meteor and web cameras.
Sar 2667 is only the 7th space rock on record discovered before hitting our planet. The asteroid was already the ninth found in February by Sárneczky and his colleagues from the Piszkéstető observatory, which is located some 60 miles (100 km) northeast of Budapest in the Mátra Mountains. The asteroid arrived two days short of the tenth anniversary of the Chelyabinsk meteorite impact, which in 2013 caused a shockwave that shattered windows on thousands of buildings in the city of Chelyabinsk in southern Russia. – Tereza Pultarova
Earthquake creates giant cracks in Earth's crust
Friday, February 10, 2023: The devastating Kahramanmaras earthquake that hit a region on the borders between Turkey and Syria on Monday (Feb. 6) has produced two more than 120-mile-long (200 kilometers) ruptures in Earth's crust that can be seen from space.
The earthquake, which came in two waves, the first peaking at 7.8 Richter scale magnitude, the second nine hours later slightly milder at 7.5, has killed over 20,000 people in the impoverished region heavily affected by the Syrian war.
This image, captured by the European Earth-observing satellite Sentinel-1 and released by the U.K. Centre for the Observation & Modelling of Earthquakes, Volcanoes & Tectonics (COMET) on Friday, Feb. 10, reveals two long ruptures created by the quakes spanning a distance of more than 120 miles (200 km) each. – Tereza Pultarova
Europe's Jupiter explorer Juice heads to spaceport ahead of launch
Thursday, February 9, 2023: Europe's Jupiter exploring spacecraft Juice has left Airbus' factory in Toulouse, France, today, and is heading to French Guiana ahead of its launch in April.
Juice (for JUpiter ICy moons Explorer) was packed into a safety container and loaded onto an Antonov aircraft, which transported it across the Atlantic Ocean to Europe's spaceport in Kourou.
Juice, which will explore the potentially life-bearing moons of Jupiter, is scheduled for launch in mid-April aboard Europe's heavy-lifter Ariane 5. – Tereza Pultarova
Astrophotographer captures stunning February full moon aligned with ancient monument
Wednesday, February 8, 2023: Astrophotographer Josh Dury captured this spectacular image of the February full moon rising behind the Glastonbury Tor, one of the U.K.'s best known spiritual sites.
Glastonbury Tor is a hill in Somerset, southwestern England near the town of Glastonbury, which is the site of the popular music festival. The enigmatic building, behind which the giant lunar disk appears in Dury's image, is the 15th century St, Michael's Tower, the only surviving element of a medieval church.
Glastonbury Tor is frequently featured in the tales of King Arthur, and it has even been suggested that the mythical warrior, who may have lived in the 6th century A.D., could be buried there.
The February full moon, also known as the Snow Moon, was at its fullest on the night of Feb. 5.-6. – Tereza Pultarova
Astrophotographer catches an enormous plasma loop erupting from sun's surface
Tuesday, February 7, 2023: A U.S. astrophotographer captured this awe-inspiring image of a giant loop of plasma arching above the sun's surface.
The loop, or prominence, as solar experts call it, is enormous. At 53,000 miles (86,000 kilometers) high and with a span of 162,000 miles (160,000 km), the mesmerizing feature is more than 20 times wider and more than four times higher than Earth. It appeared on the sun's surface on Saturday, Feb. 4, when it attracted the attention of Arizona-based astrophotographer and NASA astronomy ambassador Mark Johnston when he was scrolling through the feeds from NASA's Solar Dynamics Observatory spacecraft.
"Prominences are very dynamic and can last from an hour to a week or more, depending upon their nature," Johnston told Space.com in an email. "Prominences occur where strong magnetic field lines erupt out of the sun and then arc back to the surface. The plasma (ionized hydrogen) you see moving from left to right is following the magnetic field lines. Typically you'll find a sunspot at the points where the magnetic field lines erupt and return."
Johnston captured the sequence from his home in Scottsdale using his hydrogen alpha telescope, a type of solar telescope that enables astronomers to view light emissions from a type of energetic hydrogen ions, which appear in deep hues of red.
Hydrogen Alpha allows astronomers to see the chromosphere, the middle layer of the sun's atmosphere, where filaments and solar flares form.
"I attach my telescope to a solar video camera, which captures 85 frames per second," Johnston said. "It's important when imaging the sun to keep your exposures at 10 milliseconds or less to ensure there is no movement within each frame."

Weather satellite sees a heart form in the clouds above the Atlantic Ocean
Monday, February 6, 2023: The GOES East weather forecasting satellite of the U.S. National Oceanic and Atmospheric Administration spotted this unusual heart-shaped cloud form above the southern Atlantic Ocean.
The giant heart in the clouds appeared off the coast of Uruguay and Brazil this morning, Monday, Feb. 6. GOES East took the video sequence from an altitude of 22,000 miles (36,000 kilometers) above Earth's surface. – Tereza Pultarova
Rare green comet shines above Stonehenge during close Earth approach
Friday, February 3, 2023: Comet C/2022 E3 (ZTF) glows above Stonehenge in southern England during its closest approach to Earth in 50,000 years.
The comet, last seen from Earth long before the iconic 5,000-year-old stone circle was erected, has thrilled astrophotographers all over the world. This particular image was taken by Josh Dury, an astrophotographer from Bath, southwest England. Dury, who's been taking images of the night sky since the age of seven, told Space.com that taking the stunning portrait of C/2022 E3 (ZTF) was "one of the most challenging" astrophotography projects he had ever undertaken.
"With thick freezing fog rolling in over Salisbury plain [where the stone circle is located], my camera equipment was freezing up and there were only short interludes of clear skies," Dury wrote in an email to Space.com. "Luckily the comet was visible for a period of time where I was able to capture this image, really a once-in-a-lifetime opportunity."
The comet will now start slowly retreating in the direction of Mars and dim gradually. It will remain visible to amateur astronomers with backyard telescopes throughout the first half of February. It will then head deeper into the outer solar system and toward the Oort Cloud, where it came from. Astronomers are not certain whether C/2022 E3 (ZTF) ever visits Earth again. But even if it does, we won't be around to see it. – Tereza Pultarova
First-ever microgravity experiment using a drone
Thursday, February 2, 2023: British start-up Gravitilab has performed a first microgravity experiment with its customized quadcopter and specially designed microgravity capsule.
The remotely controlled drone carried the capsule into an altitude of 2,000 feet (600 meters). After its release, the capsule hurtled toward Earth in a freefall, creating a few seconds of simulated weightlessness inside.
The company says its drone system, called LOUIS, can provide up to 20-second-long microgravity flights, up to ten times longer than what drop towers can offer. Companies from many industries including pharmaceuticals, materials and aerospace are interested in conducting research and experiments in microgravity conditions. However, access to the International Space Station is expensive and limited, and so are Earth-based opportunities such as parabolic flights.
Gravitilab's system is the first microgravity research facility using unmanned aerial technology. – Tereza Pultarova
Elon Musk shares photo of Starship engine bay ahead of major test
Wednesday, February 1, 2023: SpaceX CEO Elon Musk shared a photo of the Starship engine bay at the company's test site in southern Texas taken ahead of a planned static firing test of the engine's first stage.
"Just leaving the engine bay of Starship," Musk said in a Tweet (opens in new tab).
The tech mogul previously hinted that Starship may attempt its debut orbital flight later this month. Prior to that, SpaceX has to complete a static firing test involving all 33 Raptor engines of the rocket's Booster 7 first stage.
Once operational, the 395-foot-tall (120 meters) Starship will be the largest rocket in the world, taller than even NASA's Space Launch System moon rocket, which sent the Artemis 1 mission around the moon last year. – Tereza Pultarova
Trio of spacecraft observes giant collision in distant universe
Tuesday, January 31, 2023: Three enormous galaxy clusters are caught in the middle of a collision in this image consisting of observations made by NASA's Chandra X-ray Observatory and the European Space Agency's XMM-Newton.
A new galaxy cluster is emerging from this collision some 780 million light-years from Earth, known as Abell 2256. In addition to X-ray observations from Chandra and XMM-Newton, the image also contains data from three Earth-based radio telescopes and one optical telescope.
Each of the telescopes provides a unique view into the processes that are underway in this giant structure that contains hundreds or thousands of individual galaxies. The X-ray component measured by Chandra and XMM reveals the location of the superhot gas filling this cluster. In this image, the gas, with temperatures of several million degrees Fahrenheit, is shown as the central bright bluish cloud.
The three radio telescopes involved, the Giant Metrewave Radio Telescope in India, the Low Frequency Array in the Netherlands, and the Karl G. Jansky Very Large Array in New Mexico, spot material emitted from supermassive black holes at the centers of individual galaxies. In this image, these radio emissions are shown as bright blots of light coming from the red-colored regions. The radio telescopes also see a vast mass of cosmic filaments depicted as the large red cloud.
Infrared and optical observations by the Pan-STARRs telescope in Hawaii are shown as dots of white and pale yellow. – Tereza Pultarova
Scary shark nebula floats above an Egyption observatory
Monday, January 30, 2023: An Egyptian astrophotographer captured this awe inspiring image of the scary Shark nebula in the constellation of Cephus lurking above Egypt's Kottamia Observatory.
"This has been the hardest object I've ever captured," Weal Omar, the author of the image and keen astrophotographer, told Space.com in an email. "It's a real challenge for anyone who loves astrophotography."
The Shark nebula is a giant cloud of thin interstellar dust and gas some 650 light-years away from Earth. Although the monstrous nebula has 15 light-years across and appears in the sky as large as 10 moons stuck next to each other, the Shark is notoriously difficult to photograph due to the wispy nature of the cloud.
This image is a composition of several shots taken on three separate nights in a remote area near the Kottamia Astronomical Observatory, the largest telescope in the Arab world, which is located some 50 miles (80 kilometers) from Egypt's capital Cairo.
"It was such scary night," Omar wrote in the email. "I heard different night animal sounds during the session, I was so scared that I even thought it was alien sounds." – Tereza Pultarova
A close-up image of the iceberg that broke off an Antarctic ice shelf this week
Friday, January 27, 2023: This detailed image shows the gap opening between the Brunt Ice Shelf in Antarctica and the iceberg that split from it on Saturday (Jan. 21).
The high-resolution image was taken by satellites of the U.S. Earth-observation company Planet on Tuesday (Jan. 24). The calving of the iceberg has nothing to do with climate change, according to experts, and was a result of natural processes that had been underway for over a decade. The iceberg split along a crack known as Chasm-1 that scientists had monitored since 2012. The new fragment, which is now slowly being carried away by the Antarctic Coastal Current, is about 600 square miles (1,550 square kilometers) in size, about as big as the London metropolitan area or little larger than Houston.
The Brunt Ice Shelf hosts the British Halley VI Research Station, which had to be moved in 2016 away from the crumbling ice block. – Tereza Pultarova
SpaceX destacks Starship ahead of booster fire test
Thursday, January 25, 2023: SpaceX has destacked its Starship megarocket after an important pre-launch test in order to perform further separate testing on the vehicle's two stages at its Starbase facility in South Texas.
"Launch and catch tower destacked Ship 24 from Booster 7 on the orbital pad today ahead of the Booster’s static fire test," SpaceX said in a Tweet.
Ship 24 is the name of this particular Starship upper stage, while Booster 7 is the first stage of the 395-foot-tall (120 meters) vehicle. The company will now perform a static fire test on Booster 7, which will involve firing all the stage's 33 Raptor engines for the first time.
To date, Booster 7 has static-fired a maximum of 14 of its 33 Raptors simultaneously. Ship 24 lit up all six of its Raptors last September. SpaceX's CEO Elon Musk previously said the giant rocket, which dwarfs even NASA's Space Launch System moon rocket, may perform its debut orbital flight as early as next month. – Tereza Pultarova
Newly discovered asteroid seen approaching Earth
Wednesday, January 25, 2023: A newly discovered asteroid that will pass very close to Earth on Friday has been photographed by an Italian astronomer as it makes its approach.
The space rock, called 2023 BU, is only about 13 to 30 feet (4 to 9 meters) wide, and was discovered last Saturday (Jan. 21) by prolific Crimea-based astronomer and telescope builder Gennadiy Borisov (the same man who discovered the first interstellar comet, which now bears his name, Borisov, in 2018)
The asteroid will pass only 2,240 miles (3,600 kilometers) from Earth's surface on Friday (Jan. 27), becoming the 4th closest asteroid ever observed apart from those that actually struck the planet, according to the Virtual Telescope website (opens in new tab). For comparison, satellites of the global navigation system GPS orbit 12,500 miles (20,200 km) above Earth, about four times farther away.
This image, however, was taken when the asteroid was still quite far, about 360,000 miles (580,000 km) away from us, which is 124,000 miles (200,000 km) farther away than the orbit of the moon.
Italian astronomer Gianluca Masi took the image on Tuesday (Jan. 24) using his robotic Elena telescope located just outside of Rome. – Tereza Pultarova
SpaceX's Starship on launchpad during major test
Tuesday, January 24, 2023: SpaceX's Starship megarocket is sitting on a launchpad at the company's Starbase facility in South Texas during a major test ahead of its debut flight.
During the test, the 395-foot-tall (120 meters) Starship, which is taller than NASA's Space Launch System moon rocket, has gone through most of the procedures it will perform on launch day including loading liquid oxygen and liquid methane propellant into the vehicle's Super Heavy first stage and Starship upper stage.
SpaceX said on Twitter (opens in new tab) it will now "destack" the rocket's stages in order to perform a static fire test with the Super Heavy's 33 Raptor engines. – Tereza Pultarova
Watch the Gulf Stream whirl across the Atlantic Ocean
Monday, January 20, 2023: The Gulf Stream whirls through the Atlantic Ocean in this image sequence based on data from European Earth-observation satellites as it transports warm water from the Caribbean toward western Europe.
The animation shows the evolution of the Gulf Stream in December 2022 and January 2023. The Gulf Stream plays an important role in European climate, warming it up considerably compared to what it would be like without it.
Scientists worry that climate change could disrupt the Gulf Stream in the future, plunging northwestern Europe into a mini ice age. Existing data already suggest that the warming steam is slowing down and potentially nearing the point of collapse. – Tereza Pultarova
Catastrophic flooding in California seen from space
Friday, January 20, 2023: Satellites of U.S. Earth observation company Planet have documented the extent of the catastrophic floods and landslides that hit California following a series of devastating storms earlier this month.
In this image, taken on Jan. 1, fields around the city of Elk Grove, near Sacramento, are seen submerged in dirty brown water in the aftermath of record-breaking downpours. Similar images have come from other parts of the sunny state, which usually struggles with drought. The storms and ensuing floods and landslides have killed at least 22 people across California. – Tereza Pultarova
Austrian astrophotographer captures Comet C/2022 E3 (ZTF) losing its tail
Thursday, January 19, 2023: An image taken by an Austrian comet hunter reveals a disconnection in Comet's C/2022 E3 (ZTF) tail that may have been caused by turbulent space weather.
Seasoned astrophotographer Michael Jäger took this image on Tuesday (Jan. 17) after driving 500 miles (800 kilometers) from Austria to Bavaria in Germany to get a clear view of the sky.
"The journey was not in vain," Jäger told Space.com in an email. He added that when it comes to comets, an astrophotographer can waste no time as these icy balls change rapidly when they reach the warmer regions in the inner solar system.
This particular image reveals what astronomers call a disconnection event, essentially a weakening in the comet's trademark tail, which makes it look as if the tail was breaking off.
According to SpaceWeather.com (opens in new tab), this disruption in the tail is likely caused by turbulent space weather, namely the stronger than usual solar wind that has been released during a recent coronal mass ejection (CME). CMEs are bursts of highly energetic particles emitted from the sun's upper atmosphere, the corona, that travel across the solar system, interfering with the atmospheres of planets and other bodies.
C/2022 E3 (ZTF), which was discovered by the Zwicky Transient Facility (ZTF) at the Palomar Observatory in California in March 2022, is making its first close approach to Earth in about 50,000 years. The comet will soon become visible to the naked eye, experts say, and will reach its closest distance to Earth on Feb.1, zooming past our planet at about one quarter the sun-Earth distance.
Jäger, who has photographed more than 1,100 comets since he took up astrophotography four decades ago, is certain to take more awe-inspiring images, which you can find on his Twitter account. – Tereza Pultarova
Earth-sized sunspot photographed in strange hydrogen light
Wednesday, January 18, 2023: A British astrophotographer has taken this image of a larger than Earth sunspot that has been battering our planet with solar flares in the past few days.
The sunspot, named AR 13190, is so large that it can be seen without a telescope, with the naked eye just with the help of sun-observing eclipse glasses (don't look at the sun's disk with unprotected eyes).
The image, taken by retired molecular biologist and life-long astronomy enthusiast Kevin Earp and shared on his Twitter (opens in new tab) account on Tuesday (Jan 17), shows the star at the center of our solar system in a specific part of the light spectrum that is emitted by energetic hydrogen atoms in the sun's chromosphere, the lower layer of the sun's atmosphere.
"This image was taken with a 100mm refractor and Daystar Quark [filter] to capture the light of hydrogen-alpha, which is not visible to the unaided eye," Earp told Space.com in an email.
In his tweet he added that taking the image was rather difficult due to the low position of the sun in the sky in this part of the year in the U.K, where he is observing from.
"Seeing in h-alpha was awful today with the #sun being so low, but I managed to catch the largest spot currently on the disk," he said, adding that "Earth could fit comfortably inside the dark umbra [the dark area of the spot], at a toasty 3,700 degrees Celsius [6,692 degrees Fahrenheit]". – Tereza Pultarova
The other greenhouse effect
Tuesday, January 17, 2023: A satellite image by U.S. Earth observation company Planet shows the Spanish Almería region covered with vegetable greenhouses. Nearly all of the ground in this 100 square-mile (260 square kilometers) area is now buried underneath plastic foil, which reflects incoming sun rays so efficiently that the region has actually cooled down in the recent decades in spite of the progress of climate change. Could this be a solution to our planet's global warming problems?
The traditionally agricultural Almería has seen its greenhouse city grow since the late 1980s as local farmers sought to increase the yields of tomatoes, cucumbers, watermelons and other produce. Spanish researchers found years ago that the sun-reflecting properties of the foil used to make the greenhouses cooled down the area by more than 0.5 degree Fahrenheit (0.3 degree Celsius). That's quite notable, considering the fact that the rest of Spain, together with the rest of Europe, is warming at a faster rate than the rest of the world. Does it mean we need more greenhouses in Europe? -Tereza Pultarova
SpaceX's Falcon Heavy launches for its fifth mission
Monday, January 16, 2023: SpaceX's Falcon Heavy rocket has lifted off for its fifth mission in history from NASA's Kennedy Space Center in Florida on Sunday (Jan. 15), lofting into orbit a secret payload by the U.S. military.
The mission, called USSF-67, was propelled into space by three modified Falcon 9 first stage boosters, two of which later successfully landed at Cape Canaveral Space Force Station, across the Banana River lagoon from Kennedy.
The third booster fell into the Atlantic Ocean as planned as it used too much of its fuel to perform a safe landing. – Tereza Pultarova
SpaceX's megarocket Starship seen from space
Friday, January 13, 2022: Satellites of European aerospace firm Airbus photographed SpaceX's megarocket Starship after it had been stacked on a launch pad at the company's Boca Chica test site in South Texas.
SpaceX is currently preparing for the debut orbital flight of the 395 feet (120 meters) tall rocket, which is taller than NASA's Space Launch System that launched the Orion spaceship for the Artemis 1 uncrewed test-flight in November.
According to SpaceX CEO Elon Musk, Starship, comprising the Ship 24 upper-stage spacecraft atop the Booster 7 first stage, could blast off for its first-ever space trip as early as late February. – Tereza Pultarova
Snoopy finally exits Orion after moon-trip
Thursday, January 12, 2022: Snoopy, the zero-gravity indicator toy astronaut, has finally been freed from its transport case after its ground-breaking trip to the moon and back aboard the Artemis I mission's Orion spacecraft.
This image, captured on Jan. 5, shows the beagle shortly after it has been unloaded from Orion by ground support teams at NASA's Kennedy Space Center in Florida.
Snoopy wasn't selected for the 25-day test flight, which lifted off on Nov. 16, by accident. The character, first introduced in 1950, has links to Apollo-era spacecraft. The lunar module of the Apollo 10 mission (which served as a rehearsal for the first lunar landing) was named Snoopy after the dog.
During the Artemis 1 mission, the Snoopy toy traveled 1.4 million miles aboard Orion as the spacecraft broke the record for the farthest distance from Earth achieved by a human-rated spaceship. The previous record was held by Apollo 13, which, however, only got that far as part of a rescue operation after an onboard explosion shortly after launch scuppered the mission's original plan to land on the moon. – Tereza Pultarova
James Webb Space Telescope reveals unexpected star formation in dwarf galaxy on Milky Way's edge
Wednesday, January 11, 2022: The James Webb Space Telescope has found evidence of star formation in a tiny galaxy in the Milky Way's outskirts.
Webb pointed its powerful NIRCam instrument at the dwarf galaxy, the so-called Small Magellanic Cloud, which orbits our galactic home 200,000 light-years away from Earth, and found pockets of star formation that have never been seen before. The image reveals new structures that appear to feed the nascent stars. – Tereza Pultarova

Monday, January 10, 2022: Virgin Orbit's Cosmic Girl Boeing 777 readies for its first mission from the U.K. at Spaceport Cornwall.
The plane is set to take off with Launcher One under its wing for the first orbital mission from British soil. The mission, called Start Me Up is a historic moment for the U.K., which is now set to become the first country in Western Europe with the capability to launch satellites to orbit. – Tereza Pultarova
Nicole Mann enjoys space station views
Thursday, January 5, 2022: NASA astronaut and Expedition 68 Flight Engineer Nicole Mann is enjoying some relaxing time inside the International Space Station's cupola in this image released by NASA on Monday (Jan. 2).
The Cupola, attached to the U.S. Tranquility module, is a dome consisting of seven windows that allow astronauts to observe Earth as well as the depths of the universe. The Cupola is probably the favorite spot on the space station for most astronauts as it provides them with a unique overview of our home planet. In this image, Mann displays the U.S. flag inside the cupola in the window next to her. – Tereza Pultarova
America's new weather sat takes over from predecessor amid superstorm
Wednesday, January 5, 2022: The GOES 18 satellite of the U.S. National Atmospheric and Oceanic Administration (NOAA) has taken over from its predecessor GOES 17 while observing a massive storm swirling above the Pacific Ocean.
The image sequence in true colors captures the storm, which brought torrential rains to California by funneling moisture from Hawai'i.
In this video sequence, GOES18 imagery begins at 1800 GMT (the timecode is visible in the lower right corner of the video).
GOES18 launched in March 2022, but it took up till now to get the spacecraft to its correct position in the geostationary orbit at 22,000 miles (36,000 kilometers) above Earth's surface, from where the craft has a constant view of the western U.S. and the Pacific Ocean.
The storm triggered a widespread evacuation operation due to the risk of flash floods and landslides especially in areas ravaged last summer by wildfires. – Tereza Pultarova
Massive eruption explodes from the sun
Wednesday, January 4, 2022: A massive eruption of magnetized particles burst from the sun on Tuesday (Jan.3), accompanied by a powerful six-hour-long solar flare.
The eruption, a so-called coronal mass ejection (CME), emerged from a sunspot on the far side of the sun, and will not hit Earth, experts say. CMEs are clouds of highly charged particles from the sun's upper atmosphere, the corona. If directed at Earth, they reach the planet within a few days. Interactions of the charged solar particles with Earth's magnetic field trigger beautiful aurora displays but also cause all sorts of problems such as power blackouts, GPS disruptions and satellite malfunctions. Solar flares, on the other hand, are bright flashes of light that arrive at the planet within eight minutes and can briefly disrupt radio communications.
While the Tuesday CME, captured in this video sequence by NASA/ European Space Agency's Solar and Heliospheric Observatory (SOHO), will miss Earth, the sunspot that produced it will likely emerge from behind the sun's eastern edge within the next two days, possible causing some rough space weather conditions in the coming weeks. – Tereza Pultarova
Record-breaking January heatwave threatens Europe's glaciers
Tuesday, January 3, 2022: A record-breaking New-Year's heatwave has swept across Europe in the first days of 2023.
With temperatures at levels usually seen in late spring, the unusual heatwave is threatening the continent's precious mountain glaciers that are already on the brink of collapse due to climate change.
This image, taken by Europe's Sentinel-2 satellite, shows the town of Altdorf in the Swiss Alps, where daytime temperatures hit 67 degrees F (19.2 degrees Celsius) on Jan. 1 and stayed above 60 degrees F (16 degrees C) throughout the night. For Altdorf, which is nestled between snow-capped 9,800-foot-tall (3,000 meters) Alpine mountain ranges, it was the warmest New Year's Day since 1864.
The warm spell comes after a summer of disastrous glacier thawing across the Swiss Alps which saw 6.2% of the mountain ice disappear. Experts usually consider a 2% annual ice loss rate as severe, according to the Conversation (opens in new tab).
New Year's Day temperature records were broken across many other central and western European countries including Denmark, the Netherlands, Poland and the Czech Republic. – Tereza Pultarova

A Space Station holiday
Friday, December 30: Traveling for the holidays can be a challenge, but what if you're traveling at 17,400 mph above Earth? Clearly, the Christmas and New Year's holiday spirit is not lost in space in this photo taken by Expedition 68 astronauts on the International Space Station.
This photo shows the astronauts inside the Cupola of the station, an observation "deck" with seven massive windows through which the Earth shines a brilliant blue in the distance. Here, the astronauts are dressed in their Christmas finery, complete with mock Christmas sweater and Santa hats! The astronauts actually celebrate two Christmases on the space station, the Dec. 25 holiday and Russian Orthodox Christmas on Jan. 6.
Pictured here are, from NASA, "Expedition 68 Flight Engineers (from left) Josh Cassada, Nicole Mann, and Frank Rubio, all from NASA, and Koichi Wakata of the Japan Aerospace Exploration Agency (JAXA)." - Tariq Malik
Starry silent night
Thursday, December 27: This stunning view shows the Gemini North telescope (second from left) and five other observatories atop the volcano Mauna Kea in Hawaii, with a long-exposure capturing the trails left by the stars as they moved across the night sky.
Gemini North is part of the International Gemini Observatory operated by the National Science Foundation's NOIRLab. It and the other observatories shown here are based at Mauna Kea because of the volcano summit's height (2.6 miles above sea level) which offers a view above most tropical clouds and humidity, allowing for sharper views and less atmospheric distortion during observations.-- Tariq Malik
Astronaut spots home for Christmas
Wednesday, December 27: Astronaut Koichi Wakata of the Japan Aerospace Exploration Agency snapped this image of Tokyo, Japan on Dec. 25, 2022, a view of his home country for Christmas.
"[We] passed over Japan a little while ago on Christmas night," Wakata wrote (opens in new tab) on Twitter while sharing the photo on Christmas, according to a Google translation from Japanese. "The area around Tokyo was also very bright and shining. It's a little bit more this year. Let's do our best again this week!"
Wakata is one of seven crewmembers on the space station representing Japan, the United States and Russia. The astronauts see 16 sunrises and sunsets a day as they orbit the Earth. -- Tariq Malik
Nebula? No, a SpaceX rocket!
Tuesday, December 27: What looks like an eerie cloud in deep space is actually something much closer to home: a SpaceX rocket.
This photo shows the spectacular exhaust plume of a SpaceX Falcon 9 rocket as it launched a Japanese lander to the moon on Dec. 11, 2022. The mission launched from SpaceX's pad at the Cape Canaveral Space Force Station in Florida at 2:38 a.m. EST, creating a dazzling nighttime scene for observers.
This view was captured as the second stage of the rocket was powering toward space, its exhaust creating ripples of wispy trails in the upper regions of Earth's atmosphere. The first stage returned to Earth to make a successful landing. – Tariq Malik
'Fried eggs' on Mars?
Monday, Dec. 26: These strange, dark "fried egg" features on Mars are just one oddity created during winter on the Red Planet.
This image, taken by NASA's Mars Reconnaissance Orbiter, shows a mix of terrain around a round crater-like feature on Mars, including sweeping dunes and hills. But most striking are the dark features to the right of the crater that scientists have nicknamed "fried eggs."
The features occur near the end of winter on Mars, when the ice begins to thaw and sublimate into atmosphere. That sublimation, where the ice turns directly to gas instead of melting into liquid first, can create the "fried egg" features as well as other strange sights like "Dalmatian spots (opens in new tab)," "spiders (opens in new tab)" and "Swiss cheese (opens in new tab)" on Mars. – Tariq Malik
NASA astronauts install new solar array
Friday, December 23, 2022: NASA astronaut Josh Cassada is seen in this image during a space walk on Thursday (Dec. 22) as the International Space Station flew above the Atlantic Ocean off the coast of Namibia.
Cassada and his colleague Frank Rubio installed a new roll-out solar array during the 7 hour and 8 minute spacewalk, which ended at 3:27 p.m. EST (2027 GMT).
The solar array will help increase the space station power generation capability by up to 30% to 215 kilowatts. – Tereza Pultarova
Mars' ice-covered South Pole
Thursday, December 22, 2022: A new image from Europe's Mars Express orbiter reveals ice-covered ridges sprinkled with dust near the Red Planet's South Pole.
The European Space Agency (ESA) released the image on Dec. 22, but the photo was actually taken in May when spring thawing set in in Mars' southern hemisphere. The image captures a crater in the Ultimi Scopuli region where layers of ice interweave with dunes of red Martian regolith.
The image was taken by the High Resolution Stereo Imaging camera onboard the Mars Express. – Tereza Pultarova
Northern hemisphere's shortest day of the year is here
Wednesday, December 21, 2022: A weather satellite takes a photo of Earth on the shortest day of the year on the Northern Hemisphere.
The image, taken by the GOES East satellite of the U.S. National Oceanic and Atmospheric Administration (NOAA) shows the planet as it approaches the winter solstice, the start of the astronomical winter. The winter solstice is the moment when the Earth's north pole reaches its maximum tilt away from the sun, resulting in the shortest day on the Northern and longest day in the Southern Hemisphere.
The 2021 Northern Hemisphere's winter solstice occurs on Wednesday, Dec. 21, at 4:48 EST (2148 GMT).
The axis of the Earth is tilted by 23,5 degrees toward the plane in which the planet orbits the sun. As a result of this tilt, the sun's rays reach the planet at a varying angle throughout the year, causing the differing lengths of the day and night at different latitudes. From tomorrow onward, the length of the day in the Northern Hemisphere will slowly start to creep up again. On Monday, March 20, the day and night will have the same duration all over the world. – Tereza Pultarova
NASA's Insight lander's farewell photo
Tuesday, December 20, 2022: NASA's InSight Marsquake detecting lander InSight may have sent its last ever photo from the red planet's surface.
NASA released this image on Monday (Dec. 19), saying that no communication has been received from the lander since Thursday (Dec. 15). InSight's death has been expected for many months now as the lander has been struggling with lack of energy due to its solar panels being covered with a thick layer of Martian dust.
InSight, which touched down on Mars in 2018, was built to monitor tectonic activity on the planet for one Martian year (about two Earth years). The mission has exceeded its designed lifetime and kept going for over four years. Still, the scientific community seems to grieve the lander's "passing" as the announcement on Twitter elicited an avalanche of emotional memes. – Tereza Pultarova
Ice-berg protecting giant Antarctic glacier from sliding into the sea is melting fast
Monday, December 19, 2022: Iceberg B-22A, which protects the so-called Doomsday Glacier in Antarctica from sliding into the sea, has been quickly breaking apart in recent months, satellite images reveal.
This time lapse sequence taken by the European Sentinel-3 satellite between Nov. 30 and Dec. 17, shows a steady stream of icy bits drifting away from the iceberg, which broke off from the tongue of the Doomsday Glacier (officially known as the Thwaites Ice Shelf) in 2002.
The Thwaites Ice Shelf is one of the largest glaciers in West Antarctica but also one of the most rapidly thawing.
The B-22A iceberg has played an important role in protecting the Thwaites Ice Shelf against warmer sea water, which would speed up its melting. Scientists worry that a disintegration of the Thwaites Ice Shelf would lead to a significant acceleration of global sea level rise. – Tereza Pultarova
This is where Perseverance will stash its Mars samples
Friday, December 16, 2022: NASA's Mars rover Perseverance is scouting the location where it will stash its precious Mars samples for a future retrieval mission that will deliver them to Earth.
The photo was taken by Perseverance's Mastcam-Z camera on Dec. 14, the rover's 646th Martian day, or sole, on the planet.
The colors of the image were digitally enhanced for a better viewer experience and don't represent the actual colors of the scene as it would appear to a human eye, NASA said in a statement (opens in new tab).
The location, where this extra-terrestrial sample depot is being built, is called Three Forks, and over the course of the next month, Perseverance is expected to deposit a total of 10 sample tubes there. Each of these tubes holds a fragment of Jezero Crater, a site that could harbor traces of past Martian life which Perseverance has been exploring since its landing on the Red Planet in February 2021. – Tereza Pultarova
Coolant leaks from Russian crew spacecraft docked to space station
Thursday, December 15, 2022: Frozen flakes of coolant spraying from the Russian Soyuz crew capsule that is currently docked to the International Space Station can be seen in this video sequence captured by an onboard camera.
The leak occurred on Thursday (Dec. 14) and only stopped when all the coolant escaped from the spacecraft's tanks. The incident is considered a serious safety issue as Soyuz is an escape vehicle for astronauts and cosmonauts if anything goes wrong at the space station.
Several astronauts commented on the situation on Twitter expressing concern.
"Serious coolant leak from the Russian Soyuz crew capsule docked to the Space Station. Not good, lots of fast decision-making going on," Canadian astronaut Chris Hatfield tweeted (opens in new tab).
His NASA colleague Scott Kelly said (opens in new tab): "Coolant leak on Russian Soyuz docked to the ISS. Serious situation."
The affected spacecraft brought to the space station cosmonauts Sergey Prokopyev and Dmitry Petelin and NASA astronaut Frank Rubio in September. Prokopyev and Petelin were just preparing for a spacewalk when the leak started.
It is not clear yet, what the accident means for the current space station crew. In addition to the three crew members who traveled to the orbital outpost on the affected Soyuz, three NASA astronauts and one Japanese astronaut that arrived on SpaceX's Crew Dragon are also currently onboard. The Soyuz was supposed to take Prokopyev, Petelin and Rubio back to Earth in March. – Tereza Pultarova
Weather satellite sees European rocket blast off with its 'brother' aboard
Wednesday, December 14, 2022: This image is not a piece of modern art but a photograph of cloud-covered central America taken by a weather forecasting satellite. The tiny bright streak toward the bottom of the image is a trail of Europe's Ariane 5 rocket shooting toward the sky with three satellites aboard.
The image was taken by the GOES-16 weather satellite of the U.S. National Oceanic and Atmospheric Administration. The Ariane 5 rocket, which can be seen blasting off the launch pad in the image, was carrying Europe's new-generation weather satellite Meteosat Third Generation, which will soon join GOES-16 in the geostationary orbit some 22,000 miles (36,000 kilometers) above Earth's surface. The satellite will help European meteorologists considerably improve their weather forecasts and better predict extreme weather events, such as summer storms, that hit the continent more frequently and with greater force than in the past because of progressing climate change. – Tereza Pultarova
Ariane 5 ready to launch Europe's new high-tech weather satellite
Tuesday, December 13, 2022: Europe's Ariane 5 rocket has been rolled out to the launch pad in Kourou, French Guiana, ahead of its launch that will deliver a new cutting-edge weather satellite into orbit.
If all goes to plan, the rocket will lift-off on Tuesday 3:30 p.m. EST (2030 GMT) and lift Europe's new Meteosat Third Generation satellite (MTG-1) into geostationary orbit.
MTG-1 is the first in a planned fleet of three spacecraft that will replace Europe's aging family of geostationary weather spacecraft. The new satellites will constantly monitor the entire European and African continent as well as parts of Asia and the Middle East, and will enable European weather forecasters to better predict severe weather events. – Tereza Pultarova
Friday, December 9, 2022: NASA's Orion spaceship was retrieved from the Pacific Ocean on Sunday (Dec. 11) shortly after it splashed down off the coast of California after its triumphant debut lunar round trip.
The capsule, which flew uncrewed to the moon and back as part of the Artemis 1 mission, was recovered by the USS Portland transport dock ship from the waters of Baja California and is currently being transported to San Diego, from where it will continue to the Kennedy Space Center in Florida on a truck.
The capsule will be subjected to extensive tests after its 25-day spaceflight to help NASA prepare for the Artemis 2 mission, which will take a human crew for a similar lunar round trip in 2024 or 2025.
The Artemis 1 mission launched atop NASA's Space Launch System rocket on Nov. 16 from the Kennedy Space Center in Florida. The capsule suffered only a few minor technical problems during its journey, which allowed it to break the record for the farthest distance from Earth ever achieved by a human-rated spacecraft. – Tereza Pultarova
Snoopy enjoying weightless fun inside Orion space capsule
Friday, December 9, 2022: Snoopy the dog, clad in an orange space suit, can be seen in this image sequence floating weightlessly inside the Orion space capsule.
Snoopy is one of five crew members of the current Artemis 1 mission, which is testing the Orion spaceship prior to a future flight with humans. Commander Moonikin Campos, a figurine fitted with sensors to measure parameters of the space environment inside the capsule, sits in his seat wearing a similar orange space suit as Snoopy. Also in the capsule are two dummy torsos called Helga and Zohar, and a Shaun the Sheep toy. The crew has an artificially intelligent assistant, the Callisto demonstration (in the middle of the control panel), which combines features of Amazon's digital assistant Alexa and the Webex video-conferencing software.
Orion is finishing its ground-breaking lunar roundtrip and will splash down in the Pacific Ocean off the coast of California on Sunday (Dec. 11). The capsule has performed with only minor glitches during its debut flight so we can likely expect the crewed Artemis 2 mission about two years from now. – Tereza Pultarova
Astronomers track Orion as it begins journey back home
Thursday, December 8, 2022: The Italy-based virtual telescope managed to photograph the Orion spaceship as it commenced its journey back home.
Orion was about 237,000 miles (382,000 kilometers) away from Earth, about as far as the moon, when the image was taken on Wednesday (Dec. 7). The imaging operation was further complicated by the fact that the moon was full at that time and shining brightly only 28 degrees away from the spacecraft.
Orion appears as a tiny little dot at the center of the image, highlighted with an arrow, while the stars dotting the surrounding universe appear as short lines. The telescope tracked the moving capsule during a 60-second period, which is why the capsule appears like a dot while the static stars look like lines.
The telescope, located near Rome, Italy, previously photographed Orion on Nov. 27, when the capsule was approaching its farthest distance from Earth. – Tereza Pultarova
50 years since Apollo 17
Wednesday, December 7, 2022: 50 years ago today, the final Apollo mission, Apollo 17, launched to the moon. The crew, commander Gene Cernan, lunar module pilot Harrison Schmitt, and command module pilot Ronald Evan, took the above image of Earth while speeding away from the planet on their way to its natural satellite.
The Apollo 17 mission culminated with Cernan and Schmitt descending onto the moon's surface in humankind's final lunar landing to date.
According to the original caption released with the photograph, the Apollo 17 mission followed a unique trajectory, which enabled astronauts for the first time to directly view and photograph Earth's South Pole. -- Tereza Pultarova
Moonikin Campos rests inside Orion capsule during lunar round-trip
Tuesday, December 6, 2022: NASA's dummy Moonikin Campos is resting inside the Orion spaceship during the Artemis 1 lunar roundtrip in a new image released by NASA.
The doll, strapped into the commander seat of the Orion crew capsule, is wearing a real space suit designed for future moon-bound astronauts. Named after NASA electrical engineer Arturo Campos who played a key role in rescuing the troubled Artemis 13 mission in 1970, the mannequin is fitted with dozens of sensors designed to assess the effects of the deep space environment on the human body. Unlike astronauts working on the International Space Station, who are protected by Earth's magnetic field, space travelers on lunar round trips will be subject to much higher levels of cosmic radiation, which can be harmful to their health.
The image, captured by an onboard camera inside Orion, also reveals the Callisto technology demonstration developed by Lockheed Martin in collaboration with Amazon and Cisco, which is essentially a space-grade combination of the Alexa digital assistant and the Webex video-conferencing tool.
Moonikin Campos' other companions are two dummy torsos named Helga and Zohar, which are making additional measurements of the environment, and two plush toys, Snoopy and Shaun the Sheep. – Tereza Pultarova
Indonesian volcano spouts lava one year after deadly eruption
Monday, December 5, 2022: The Landsat 9 satellite captured an eruption of the Semeru volcano on Indonesia's Java island on Sunday, Dec. 4.
Landsat 9 is a joint mission by NASA and the U.S. Geological Survey. The spacecraft, which orbits Earth at the altitude of 440 miles (705 kilometers), spotted the thick plume of volcanic ash rising from the volcano shortly after local authorities raised the warning status to the highest level.
The volcano, one of the most active in the region, started spurting lava at 2:46 am local time, Monday, Dec.5 (2:46 pm EST, on Sunday, Dec.4) . No injuries have been reported so far, according to news reports, but authorities ordered about 2,000 people to evacuate from a 5 mile wide (8 km) zone around the volcano. The eruption began exactly a year after the tragic eruption of December 2021, which killed dozens of people in nearby villages.
Experts estimate that the ash plume from the eruption could have reached altitudes of about 9 miles (15 km). – Tereza Pultarova
New view of Pillars of Creation combines images from two Webb's instruments
Friday, December 2, 2022: By combining images of the iconic Pillars of Creation taken by the two main cameras on the James Webb Space Telescope, scientists created a new view of the imposing dust structure that reveals its complexity in unprecedented detail.
The new image is a composite of previously released photographs taken by Webb's Near-Infrared Camera (NIRCam) and the Mid-Infrared Instrument (MIRI). NIRCam detects the shorter wavelengths of the near infrared light emitted by objects in the universe and is a specialist in finding stars and warmer, denser dust accumulations where stars form. MIRI scans the universe in the longer, mid-infrared wavelengths and excels at detecting cosmic dust.
Images obtained by these two instruments were previously released separately, with the one taken by NIRCam studded with stars, while MIRI's image was a ghostlike cloud of gray.
Adding NIRCam's view to that of MIRI enlivens the deadness of the dusty Pillars with the sparkle of hundreds of stars, big and small. Newborn stars can be seen as tiny reddish dots scattered in the thickest, darkest parts of the dust cloud.
Pillars of Creation, first imaged by the Hubble Space Telescope in the mid-1990s, are one of the nearest star-forming regions to Earth. Located in the Eagle Nebula, some 6,500 light-years away, the Pillars serve as a cosmological lab that will help Webb unravel the processes of star creation in a way impossible before. – Tereza Pultarova
Cavorting galaxies(opens in new tab)
Thursday, 1 December: This dramatic image captured by the James Webb Space Telescope displays a galactic merger of cosmic proportions known to astronomers as II ZW 96.
II ZW 96 lies approximately 500 million light-years from Earth and is located in the constellation Delphinus.
The two bright cores of each galaxy are clearly visible in this image but the swirling arms of each galaxy have been twisted out of shape by the collision. - Daisy Dobrijevic
Mauna Loa eruption spotted from space(opens in new tab)
Wednesday, November 30: This view of Mauna Loa by a Maxar Technologies satellite on Nov 28, 2022, shows the dramatic scenes unfolding during Mauna Loa's eruption. Here, the lava flows move along the Northeast Rift Zone on Hawaii's Big Island.
Hawaii's Mauna Loa, the world's largest active volcano, began erupting on Sunday (Nov. 27), the first eruption in almost 40 years. The volcano last erupted in 1984 when it sent a lava flow barreling toward the city of Hilo.
Mauna Loa occupies more than half of Hawaii's Big Island and rises 13,679 feet (4,169 meters) above the Pacific Ocean, according to USGS (opens in new tab). It has erupted 33 times since the first well-documented eruption in 1843. - Daisy Dobrijevic

Record-breaking snowfall covers Buffalo
Friday, November 25, 2022: European Earth-observing satellite Sentinel-2 watched from orbit as a record-breaking amount of snow blanketed the city of Buffalo in the north of the U.S.
The unprecedented snowfall, which buried the streets of Buffalo in 6 feet (1.8 meters) of snow within 48 hours, was a result of the so-called Lake Effect, a weather phenomenon that occurs in the area south of the Great Lakes on the border between the U.S. and Canada.
The Lake Effect happens when cold dry air from the Canadian inland sweeps across the lakes, sucking in moisture. Once the air is saturated with humidity, the clouds dump the water in the form of snow on the areas south of the lakes.
According to the World Economic Forum, the Lake Effect is getting more intense as a result of climate change. Sentinel-2 took this image on Tuesday (Nov. 22) while locals struggled to clear the snow off streets. – Tereza Pultarova
See you on the far side of the moon
Thursday, November 24, 2022: NASA's Orion spacecraft captured this image of the far side of the moon using its optical navigation camera during its close approach to the moon's surface earlier this week.
The image was taken on Monday (Nov. 21), five days after Orion set off for its debut uncrewed lunar trip from NASA's Kennedy Space Center in Florida. Humans can only get a glimpse of the far side of the moon through space probes as it never faces our planet. During the Monday flyby, Orion approached the moon to a distance of only 80 miles (130 kilometers). NASA shared the image on its Flickr account on Thursday (Nov. 24). – Tereza Pultarova
Europe's new astronauts
Wednesday, November 23, 2022: 17 finalists of the European Space Agency's (ESA) astronaut selection on stage in Paris at the end of the agency's ministerial conference on Wednesday, Nov. 23.
ESA chose five new astronaut trainees and a paraastronaut out of the 17 finalists with the rest joining what the agency calls a reserve pool. While the five new astronauts will commence their training immediately, ESA might call upon one of the reservists in the future in case it needs extra man-power in space.
The new astronaut class includes two women: aerospace engineer and helicopter test pilot Sophie Adenot of France and British astrophysicist Rosemary Coogan. Paralympic sprinter and trauma surgeon John McFall is the parastronaut who will help ESA evaluated whether people with certain types of disabilities can safely participate in space flight. Belgian neuroscientist Raphaël Liégeois, Spanish aerospace engineer Pablo Álvarez Fernández and Swiss emergency surgeon and paratrooper Marco Alain Sieber are also joining the team. – Tereza Pultarova
Orion continues epic journey
Tuesday, November 22, 2022: NASA's Orion capsule took this selfie with the crescent moon on the sixth day of its epic journey around Earth's natural satellite.
Orion, which is now performing an uncrewed test flight as part of the Artemis 1 mission, is fitted with 16 monitoring cameras on its structure and in its interior. Ground controllers are using these cameras not only to share stunning views from the milestone flight with the mission followers, but also to inspect the spacecraft, which in the future will take a human crew on a similar trip.
Orion is currently heading to enter the distant retrograde orbit around the moon, an elliptical orbit that will take it as far as 40,000 miles (64,000 km) away from the lunar surface. During its time in this orbit, Orion will break a record for the farthest distance from Earth achieved by a human-rated spacecraft. The existing record was established by the Apollo 13 mission, which, however, got so far as part of an emergency rescue operation after an explosion impaired the spacecraft's systems. – Tereza Pultarova
Moon and Earth in one view as Orion nears closest approach
Monday, November 21, 2022: NASA's Orion spaceship took this stunning photo of Earth and the moon ahead of its closest pass at the planet's natural satellite on Monday morning.
The uncrewed capsule was lofted to space for its Artemis 1 mission by NASA's Space Launch System mega rocket on Wednesday (Nov. 16) to test technologies needed for humankind's return to the moon. Orion's cruise has been smooth so far. The capsule made its closest approach at 7:44 a.m. EST (1244 GMT), skimming just 80 miles (130 kilometers) above the lunar surface.
Later on Monday, Orion will fire its engines in order to enter the distant retrograde orbit around the moon, an elliptical orbit, which will take it as far as 40,000 miles (64,000 km) from the lunar surface. The capsule will return to Earth on Dec. 11. – Tereza Pultarova
Orion snaps blue marble in black and white
Friday, November 18, 2022: NASA's Orion space capsule continues on its way to the moon, snapping stunning images as it flies. This beautiful black and white portrait of our planet was taken by the capsule's optical navigation camera, which is used to determine the spacecraft's position in space.
Orion was lofted to space by the giant Space Launch System rocket on Wednesday (Nov. 16) early in the morning. The capsule separated from the mega-booster shortly thereafter and performed two engine burns since, putting itself firmly on the trajectory to Earth's natural companion.
Orion will make its closest approach to the moon on Monday (Nov. 21), passing only 60 miles (100 kilometers) above the moon's surface. The capsule will then spend about a week in the moon's orbit before heading back to Earth. Orion is expected to splash down in the Pacific Ocean off the coast of California on Dec. 11. – Tereza Pultarova
Orion leaving behind its blue marble
Thursday, November 16, 2022: The moon-bound Orion spaceship has taken this stunning sequence of images of the receding Earth in the first hours after it commenced its ground-breaking journey from the Kennedy Space Center.
The capsule, built jointly by NASA and the European Space Agency (ESA), launched on its Artemis 1 mission on Wednesday (Nov. 16) early in the morning. The purpose of this uncrewed trip to Earth's natural satellite is to prove the technology is fit to carry humans. Orion will make the closest approach to the moon on Monday (Nov. 21), passing just 60 miles (97 kilometers) above the moon's surface. The capsule will then spend about a week orbiting the moon before commencing its journey back home.
Orion is expected to splash down in the Pacific Ocean off the coast of California on Dec. 11. Throughout its journey, Orion will be sending home images taken by 16 cameras mounted on its structure. – Tereza Pultarova
Space.com collaborator captures the wake of Artemis 1 launch
Wednesday, November 16, 2022: A trail of curling exhaust fumes left behind by NASA's Space Launch System moon rocket after it left its launch pad at the Kennedy Space Center in Florida was captured by Space.com's collaborator Josh Dinner.
Josh captured the image shortly after the 322-foot-tall (100 meters) rocket cleared the pad at 1:47 a.m. EST (0647 GMT) on Wednesday, Nov. 16. The lift off followed a short delay caused by an issue with an ethernet switch at a radar monitoring site and a brief hydrogen fuel leak.
The rocket boosted an uncrewed Orion spaceship for the groundbreaking Artemis 1 mission to the moon and back, which will pave the way for humankind's return to the moon later this decade.
In a post-launch press conference, NASA admitted it detected some minor technical glitches during the milestone launch, but overall, all went as planned, to the delight of the Artemis 1 team and NASA leadership, as well as enthusiastic onlookers in Florida and all over the world. – Tereza Pultarova
NASA's moon rocket standing tall after battering by Hurricane Nicole
Tuesday, November 15, 2022: NASA's Space Launch System (SLS) moon rocket is standing tall in the moonlight after being battered by Hurricane Nicole last week ahead of its planned debut launch. The photo was taken by NASA photographer Bill Ingalls on Monday, Nov. 14.
NASA chose not to roll SLS with the Orion capsule atop back to the assembly building ahead of Hurricane Nicole's landfall on Thursday, leaving it on Launch Pad 39 B to weather the storm.
Nicole battered the rocket with wind gusts of more than 80 mph (130 km/h), but subsequent inspections revealed only relatively minor damage on the rocket and the capsule. The storm stripped off some of the insulating caulking on Orion, which smooths out a slight gap in the exterior of the spacecraft. NASA engineers, however, concluded that the problem is not a showstopper for the upcoming launch. If all goes to plan, SLS will lift off at 1:04 a.m. EST (0604 GMT), sending the uncrewed Orion for a lunar round trip. The mission, the first of the NASA-led Artemis program, will pave the way for humans' return to the moon in the coming years. – Tereza Pultarova
Solar snake slithers across the sun
Monday, November 14, 2022: The European Solar Orbiter spacecraft captured an odd snake-like filament crawl across the sun's surface just before a massive plasma eruption.
The filament, which originated in a sunspot, a cooler region on the sun's surface where the star's magnetic field is twisted, took three hours to slither across the sun's disk at a speed of 105 m per second (170 km/s), the European Space Agency (ESA), which operates the spacecraft, wrote in a statement (opens in new tab).
In the time lapse sequence reconstructed from images captured by Solar Orbiter's Extreme Ultraviolet Imager the "snake"glides across the disk within a second.
Because the odd occurrence was followed by a coronal mass ejection (CME), an eruption of hot plasma from the sun's upper atmosphere, the corona, scientists think the two phenomena might be connected. – Tereza Pultarova
NASA's inflatable Mars-landing shield after test space flight
Friday, November 11, 2022: NASA's experimental inflatable Mars landing shield LOFTID is seen in this photo after being retrieved from the ocean following its test descent through Earth's atmosphere on Thursday (Nov. 10).
The LOFTID team also recovered a data module that was ejected from the flying saucer-like shield before splashdown, and which stores data recorded during the demonstration.
LOFTID, which could pave the way for technology that could allow landing larger spacecraft on Mars, launched to space on Thursday morning aboard United Launch Alliance's Atlas V rocket as a secondary payload with the Joint Polar Satellite System-2 (JPSS-2).
While for JPSS-2, the launch marked the beginning of a years-long climate monitoring mission, LOFTID headed straight back to Earth. Unlike previously used heat shields, LOFTID, thanks to its malleable nature, can be squeezed inside a rocket fairing even if its diameter exceeds that of the fairing. Thanks to its larger size, it can then slow down heavier spacecraft during the descent through a planet's atmosphere. – Tereza Pultarova
Inflatable Mars landing shield completes space-flight test
Thursday, November 10, 2022: A flying saucer-like inflatable shield has completed a descent from Earth's orbit and splashed down into the ocean, demonstrating what a future Mars landing technology may look like.
The LOFTID experiment (for Low-Earth Orbit Flight Test of an Inflatable Decelerator) launched into space on Thursday (Nov. 10) early in the morning as a secondary payload on the United Launch Aliance's Atlas V rocket, which also lofted the climate monitoring Joint Polar Satellite System-2 (JPSS-2).
Unlike JPSS-2, which is set to embark on a years-long mission, LOFTID headed straight back to Earth, unfolding into its full size and slowing down in the atmosphere through air drag.
In the future, similar shields may enable landing larger payloads on other planets, as their size is not limited by the width of the payload fairing of the launching rocket. NASA is now evaluating data from the test to see how the novel shield performed. – Tereza Pultarova
Cygnus cargo vehicle reaches space station despite solar panel malfunction
Wednesday, November 9, 2022: The Cygnus cargo spacecraft SS Sally Ride reached the International Space Station despite failing to deploy one of its two solar panels shortly after launch.
The spacecraft, carrying a record-breaking 4.1 tons (3.7 metric tons) of scientific experiments and supplies, arrived at the orbital outpost on Wednesday (Nov. 9) early morning. NASA astronaut Nicole Mann, assisted by her colleague Josh Cassada, captured the capsule with the space station's robotic arm at 5:20 a.m. EST (1020 GMT) before attaching it to the Earth-facing port of the station's Unity module.
SS Sally Ride, built by U.S. aerospace giant Northrop Grumman launched from NASA's Wallops Flight Facility on Wallops Island, Virginia, on Monday (Nov. 7) at 5:32 a.m. EST (1032 GMT) atop an Antares rocket. Eight minutes later, the capsule separated from the rocket's upper stage as planned but failed to deploy one of its solar panels, raising concerns about its ability to reach the space station. The spacecraft made it to its destination despite the setback as scheduled. – Tereza Pultarova
Tropical storm Nicole swirls above the Caribbean
Tuesday, November 8, 2022: Storm Nicole swirls above the Caribbean as it approaches Florida, forcing NASA to consider emergency scenarios for its upcoming Artemis 1 test flight to the moon.
The storm, seen in this video sequence captured by the GOES-17 satellite of the U.S. National Oceanic and Atmospheric Administration (NOAA), formed early on Monday (Nov. 7) morning.
Meteorologists expect the storm to strengthen over the coming days and hit Florida's east coast as a Category 1 Hurricane on Thursday morning. NASA's Kennedy Space Center, where the agency's Space Launch System moon rocket currently sits on a launch pad prepared for its scheduled debut flight, is in the zone expected to be affected by Nicole. NASA has not yet decided whether to roll the rocket back into the assembly building. The Artemis 1 mission, which is the first step in NASA's plans to put humans back on the surface of the moon, has already been delayed twice due to technical problems. – Tereza Pultarova
Japanese weather satellite observes moon rise from beyond Earth
Monday, November 7, 2022: The odd shape emerging above Earth is actually the moon rising this morning as seen by the Japanese weather forecasting satellite Himawari.
The satellite took the image from its perch in the geostationary orbit 22,000 miles (36,000 kilometers) above Earth where satellites appear fixed with respect to the planet's surface.
The odd shape of the rising moon is caused by the refraction of light in Earth's atmosphere, Simon Proud, a scientist at the U.K. National Center for Earth Observation, who shared the image on his Twitter accoun (opens in new tab)t, told Space.com.
"The path of the light is getting bent as it travels through the atmosphere. Just like when you look at a straw in a glass of water," said Proud. – Tereza Pultarova
Moon rocket returns to launch pad
Friday, November 4, 2022: NASA's moon-bound Space Launch System rocket is back on launch pad 39B ahead of its debut test launch which will send the uncrewed Artemis 1. mission for a lunar roundtrip.
Engineers rolled out the rocket from the iconic Vehicle Assembly Building at the Kennedy Space Center in Florida on Friday, Nov. 4, with lift-off currently scheduled for Nov. 14. The test flight will see an empty Orion capsule fly to the moon and back to verify technical systems ahead of the first flight with astronauts, which may take place in 2024.
The debut flight, which will pave the way for humankind's return to the moon, has been delayed several times due to ongoing problems with leaking hydrogen. – Tereza Pultarova
Chinese rocket debris spotted by satellite
Thursday, November 3, 2022: The core stage of China's giant Long March 5B rocket that launched the final module of the country's space station on Oct. 31 has been photographed hurtling back to Earth by an Earth-observing satellite.
The 23-ton (21 metric tons) rocket stage was caught by cameras on board a nano-satellite operated by Australian start-up HEO Robotics amid an outcry of criticism of China's reckless treatment of the space junk problem.
Neither China nor all the world's experts currently analyzing the rocket's orbit know where it's going to crash over the weekend. China has previously been slammed for irresponsible behavior as similar out-of-control rocket returns took place following previous launches of its space station modules.
HEO Robotics shared the image on its social media channels on Thursday (Nov. 3), saying: "Our space-to-space imagery and intelligence will continue to support strategic decision-making and accountability efforts by making space transparent." – Tereza Pultarova
Moon rocket readies for rollout ahead of next debut launch attempt
Wednesday, November 2, 2022: NASA's Space Launch System rocket with the Orion capsule atop readies for its rollout from the Vehicle Assembly Building at NASA's Kennedy Space Center ahead of its planned debut launch later this month.
NASA said it will move the 322-foot-tall (100 meters) rocket onto Pad 39B later this week. The launch, which will propel the uncrewed Orion capsule for a test flight around the moon and back, is currently scheduled for Nov. 14.
Part of the Artemis I mission, the test flight will prove that the rocket and the capsule are fit to carry human astronauts as part of NASA's renewed push to establish a permanent human presence on Earth's natural satellite.

Falcon Heavy side booster returns to Earth after a successful launch
Tuesday, November 1, 2022: One of the side boosters of SpaceX Falcon Heavy rocket that lofted a classified U.S. military satellite into orbit on Tuesday (Nov. 1) has been photographed during its return to Earth.
The Tuesday launch was only the fourth for Falcon Heavy, the most powerful rocket currently in service, and first since 2019. The flight also represented the 50th SpaceX mission of 2022 overall, as the company's lighter, workhorse rocket Falcon 9 has been lifting off on a weekly basis this year.
The launch of Heavy went without a hitch with both of the rocket's side boosters returning to Earth smoothly and landing at neighboring launch pads at NASA's Kennedy Space Center in Florida. The rocket's central stage didn't soft land this time as all of its fuel was needed to directly insert the secret USSF-44 satellite into the geostationary orbit 22,000 miles (36,000 kilometers) above Earth's surface. – Tereza Pultarova
Amateur astrophotographer snaps a stunning photo of distant nebula
Monday, October 31, 2022: This stunning image of a dusty region in the Milky Way galaxy known as the Heart Nebula wasn't taken by any famous space telescope but by an amateur astrophotographer in Cairo, Egypt.
Wael Omar created this image of the nebula, which is located some 7,500 light-years away from Earth, from the roof of his house in Cairo. To overcome the city's air-pollution and light pollution, both of which obstruct the view of the cosmos, he collected 50 hours of observations over a 10-day period, which he then processed into this stunning image.
The Heart Nebula was discovered by astronomer William Herschel in 1787. Although very faint, the nebula, made of ionized hydrogen gas, is rather large, spanning an area four times the size of the full moon. The nebula is located within the famous W-shaped constellation Cassiopeia. For more of Wael' stunning images, visit his Instagram page @waelomar_astrophotography. – Tereza Pultarova
Brand new Mars crater exposes subsurface ice
Friday, October 28, 2022: A fresh new crater on Mars created by a meteoroid strike on Christmas Eve 2021 has been photographed by NASA's Mars Reconnaissance Orbiter, revealing layers of surprise subsurface ice.
The space rock impact that created the crater sent powerful shockwaves through Mars' crust that were immediately picked up by NASA's InSight lander, which monitors the planet's seismic activity.
From the strength of the shockwaves, scientists understood that the rock that triggered the earthquake must have left behind a crater. They were eventually able to find the new crater in images taken by the Mars Reconnaissance Orbiter. A 492-foot-wide (150 meters) and 70-foot-deep (21 meters) hole was gaping in the surface with material ejected by the impact scattered as far as 23 miles (37 kilometers) away.
Scientists say this was the largest crater they have ever observed to form on any body in the solar system nearly in real time. The powerful impact exposed blocks of water ice underneath the surface, which surprised scientists as the impact took place in one of the warmest areas near the red planet's equator. – Tereza Pultarova
The highest resolution movie of the solar corona
Thursday, October 27, 2022: The Europe-led Solar Orbiter spacecraft took the highest-resolution movie ever of the upper layer of the sun's atmosphere, the corona, during its recent close approach to the sun.
The video sequence, taken with Solar Orbiter's Extreme Ultraviolet Imager (EUI), reveals the corona in a tranquil almost motionless state. The video was taken on Oct.13 when Solar Orbiter was at only 29% of the sun-Earth distance from the star. Each pixel in the movie covers an area 65 miles wide (105 kilometers), which means that 17 Earths would fit across the image.
The corona, over a million degrees Celsius hot, is a source of the solar wind and coronal mass ejections, bursts of plasma that affect space weather around Earth. To see the corona this quiet is a bit surprising as the sun's activity has been picking up lately as the sun nears the peak of its current cycle of activity which will take place in 2025. – Tereza Pultarova
Moon casts shadows over Scandinavia during solar eclipse
Wednesday, October 26, 2022: Europe's Earth-observing satellite Sentinel-3 captured the brief moment when the moon cast a vast shadow over Scandinavia in Northern Europe during the solar eclipse on Oct. 25.
The eclipse was only partial with a little over 50% of the sun's disc hidden behind the moon as viewed from Norway. Sentinel-3 flew over the area at 10:12 GMT, just as the eclipse was nearing its maximum. The satellite took the image from its orbit at the altitude of about 500 miles (800 kilometers).
Eastern parts of the Arctic and sub-Arctic regions offered even better conditions for observing the Oct. 25 eclipse. In western Siberia, particularly in the Russian city of Nizhnevertovsk, over 86% of the sun's disk was obscured during the peak of the eclipse. – Tereza Pultarova
Moon's shadow crossing Earth during solar eclipse
Tuesday, October 25, 2022: The moon's shadow skimming the face of Earth during the partial solar eclipse on October 25 in a video sequence captured by the European Meteosat weather-forecasting satellite.
The video was processed by Earth-observation scientist Simon Proud of the U.K.'s space science laboratory RAL Space.
"Look near the top of the video, especially on the right hand side: Can you see the moving dark area? That's the shadow!" Proud said in a Tweet, sharing the sequence.
Meteosat is a geostationary satellite that sits in a fixed spot relative to Earth's surface at an altitude of 22,000 miles (36,000 kilometers). From this vantage point, the satellite, built to observe the movement of cloud system above the planet, captured a complementary view to the celestial spectacle observed from Earth.
A solar eclipse occurs when the moon passes between the sun and Earth. Depending on the level of alignment between the three bodies, the eclipse can be either total or partial. The eclipse of Oct. 25 reached a maximum near the North Pole where the moon briefly covered 82% of the sun's visible disk. The eclipse was the second and final solar eclipse of 2022. The next solar eclipse will be a total one for parts of the Southern Hemisphere including Australia and will occur in April 2023. – Tereza Pultarova
Stars being born inside Pillars of Creation
Monday, October 24, 2022: The red dots in this zoomed-in segment of the James Webb Space Telescope's photo of the famous Pillars of Creation are newborn stars only a few hundred thousand years old.
The Pillars of Creation, part of the Eagle Nebula in the constellation Serpens, are one of the closest star-forming regions to Earth. The Hubble Space Telescope has imaged the spectacular clouds of cosmic dust several times since 1995, but could never penetrate the cloud's surface. The James Webb Space Telescope, with its heat-detecting infrared vision, has now revealed what is happening inside the Pillars, allowing astronomers to observe star formation in detail and on a large sample of emerging stars. – Tereza Pultarova
Veteran X-ray telescope captures powerful gamma ray burst
Friday, October 21, 2022: Europe's veteran XMM-Newton space telescope, which detects high energy X-ray radiation emitted by objects in the universe, observed the immediate aftermath of the gamma ray burst of the century.
According to the European Space Agency (opens in new tab) (ESA), which released the image on Friday (Oct. 21), operators pointed XMM-Newton in the direction of the constellation Sagitta, from where the gamma ray burst emerged on Sunday (Oct.9), shortly after the flash was first detected.
The telescope, launched in 1999, then took spectacular images of the energetic rays scattering off interstellar dust as they raced through our galaxy at nearly the speed of light.
Astronomers said the gamma ray burst, officially named GRB 221009A, was one of the strongest ever detected and also one of the nearest. ESA said that many of its spacecraft detected the aftermath of the event, which was so powerful that it ionized Earth's atmosphere, briefly disrupting long wave radio communication on Earth. – Tereza Pultarova
Hubble catches a galaxy cannibalizing another
Thursday, October 20, 2022: The Hubble Space Telescope captured an image of two strangely interacting galaxies, one of which appears to be sucking out stars from the other.
The two galaxies in question are NGC 2799 (on the left), which is being stretched by the gravitational pull of the larger NGC 2798 galaxy (on the right).
A thin bridge of stars is visible in the image leading from the smaller galaxy to the heart of the larger one.
These two galaxies will likely merge completely in the future, the European Space Agency said in a statement (opens in new tab). But this process is likely going to take hundreds of millions of years. Although the idea of a galactic collision sounds intimidating, stars in both galaxies usually survive such encounters as the vast amount of free space between the balls of matter ensures that they safely avoid each other during the process. – Tereza Pultarova
The James Webb Space Telescope re-images Hubble's iconic Pillars of Creation
Wednesday, October 19, 2022: NASA's James Webb Space Telescope has taken a look at the Pillars of Creation, an object of one of the most iconic images of its predecessor Hubble.
Using its infrared super-vision, Webb peered deeper into the nebula than Hubble ever could, revealing stars being born inside the dense clouds of gas and dust that form the spectacular columns that are part of the Eagle Nebula located in the constellation Serpens some 7,000 light years from Earth.
The image, taken by Webb's Near-Infrared Camera (NIRCam) is virtually sprinkled with sparkles of various sizes and luminosity levels, many of which are nascent stars just springing into life out of the coalescing dust in the Pillar's clouds. – Tereza Pultarova
Martian pebbles photographed by NASA's Perseverance rover
Tuesday, October 18, 2022: NASA's Perseverance rover took an up-close view of Jezero Crater surface covered with sand and regularly shaped pebbles.
The rover took the image using its SHERLOC WATSON camera located at the end of its robotic arm on Sunday, Oct.16, its 589th sol on the red planet. The rover has recently experienced technical problems when collecting its 14th rock sample. The rover was able to collect drill the promising rock, but failed to seal the test tube. The samples the rover collects will be brought to Earth by a return mission in the early 2030s. – Tereza Pultarova
Cosmic dust set aflame by the most powerful explosion ever observed
Monday, October 17, 2022: Rings of cosmic dust set alight by extremely energetic radiation from a record-breaking gamma ray burst glow in this image captured by NASA's Swift X-ray telescope.
The gamma ray burst GRB 221009A flashed from a galaxy over 2 billion light-years away on Oct. 9 in what has been the most energetic such event ever observed. Gamma ray bursts are the most energetic explosions known to occur in the universe, second only to the Big Bang. They are believed to be a result of supernova explosions of dying supermassive stars. Just as the star collapses into a new-born black hole, it unleashes a beam of light that brightens up the universe for a brief period of time of a few seconds to a couple of minutes.
Telescopes all over the world are now aiming at spot in the sky were GRB 221009A came from, hoping to gather enough data to shed more light on these formidable explosions. – Tereza Pultarova
Crew-4 leaves International Space Station
Friday, October 14, 2022: Four astronauts of the International Space Station's Crew-4 have left the orbital outpost today in a SpaceX Dragon capsule named Freedom.
The capsule undocked from the space station at 12:05 p.m. EDT (1605 GMT). On board were NASA astronauts Bob Hines, Kjell Lindgren and Jessica Watkins and the European Space Agency's Samantha Cristoforetti, who spent five and a half months in space. Their departure was twice delayed because of bad weather in Florida. The capsule will splashed down near Jacksonville, Florida, on Saturday (Oct. 15), NASA officials said.
The quartet of astronauts was replaced by Crew-5 who arrived on Oct.6. -- Tereza Pultarova
Mars orbiter takes a stunning shot of Martian moon with Jupiter
Thursday, October 13, 2022: The European Mars Express spacecraft took a stunning sequence of images capturing the Martian moon Deimos with Jupiter and its four main moons.
The High Resolution Stereo Camera aboard the spacecraft captured the sequence consisting of 80 images in February, but the European Space Agency, which operates the spacecraft, only released it on Oct. 13.
The rugged Martian moon Deimos crosses the spacecraft's view in the sequence with Jovian moons Europe, Ganymede, the gas giant planet Jupiter, and the moons Io and Callisto aligned in the background from left to right.
Mars Express was 460 million miles (745 million kilometers) away from Jupiter when it took the images. – Tereza Pultarova
Solar Orbiter speeds toward the sun
Wednesday, October 12, 2022: The Europe-led Solar Orbiter spacecraft captured this video sequence with one of its high-res cameras as it sped toward the star at the center of our solar system ahead of its close approach, the perihelion, on Oct.12.
The sequence shows the sun's surface sparkling with activity in its gaseous atmosphere as it evolved between Sept. 20 and Oct. 10. Solar Orbiter makes regular close passes at the sun at about one third of the sun-Earth distance (within the orbit of the planet Mercury). Only NASA's Parker Solar Probe has ever dared closer to the star, but that spacecraft doesn't carry a sun-facing camera, as its optics wouldn't survive in the hellish environment the probe encounters.
Together, these two spacecraft make leaps in our understanding of the behavior of our life-giving star. – Tereza Pultarova
Robots help with experiments on International Space Station
Tuesday, October 11, 2022: NASA's Astrobee robots are assisting astronauts in conducting experiments aboard the International Space Station.
The Astrobee robots are free-flying robots developed to help astronauts with routine tasks so that the humans can spend more time doing the fun stuff. According to NASA, the cube-shaped robots can take inventories and document experiments using their built-in cameras or even move cargo through the space station.
In this image, shared on Twitter (opens in new tab) by European astronaut Samantha Cristoforetti, the Astrobees are helping to test software designed to optimize spacecraft docking and undocking. – Tereza Pultarova
Webb captured the birth of a distant solar system
Monday, October 10, 2022: The James Webb Space Telescope captured the birth of a distant solar system in a famous star-birthing nebula.
The small U.F.O-like speck in the middle of the image is a young star, only about 1 million years old, surrounded by a protoplanetary disk from which planets are expected to spring to life. The cloud of dust and gas from which the star emerged is the famous Orion Nebula, a well-known star-forming region some 1,344 light years away from Earth located in the constellation Orion.
The James Webb Space Telescope, with its infrared super-vision can peek through the clouds of gas and dust right into the heart of such star-forming regions. – Tereza Pultarova
Europa gets a psychedelic treatment in a new image from Juno's close flyby
Friday, October 7, 2022: An image of Jupiter's ocean-bearing moon Europa taken during a recent flyby by NASA's Juno probe received a psychedelic treatment revealing the mysterious world in unexpected colors.
The picture was taken by Juno's JunoCam camera during the pass on Sept. 29 and was processed by citizen scientist Fernando Garcia Navarro. Navarro's unorthodox treatment lent the rather plain white and brownish moon a psychedelic look, creating a bridge between science and art. – Tereza Pultarova
Europe's delayed Ariane 6 rocket completes upper stage test
Thursday, October 6, 2022: The European rocket-maker ArianeGroup has successfully tested the upper stage of its new, delayed, heavy-lift rocket Ariane 6.
The upper-stage, which can be repeatedly ignited, completed its first hot-fire test at a rocket research laboratory in Lampoldshausen, Germany, on Wednesday (Oct. 5). During the test, engineers simulated conditions the stage will experience in flight. The upper stage, responsible for injecting customer payloads into correct orbits, is the part of the rocket that operates for the longest time. Further tests have to be performed before the rocket can get a green light for its debut flight, which was originally scheduled for 2020. – Tereza Pultarova

The launch comes a day after reports of a Russian nuclear convoy seen heading toward the borders of the invaded Ukraine appeared in the news. The launch is scheduled to take place on Wednesday, Oct. 5, at 12:00 p.m. EDT from Launch Complex 39 A at the Kennedy Space Center. – Tereza Pultarova
DART's death witness LICIACube snaps a photo of Earth with the moon
Monday, October 3, 2022: The tiny cubesat that traveled with NASA's DART mission to the Didymos binary asteroid system to witness DART's collision with the rock snapped a picture of Earth and the moon.
The picture, released by the LICIACube team on Twitter on Sunday (Oct. 2), was taken just before DART smashed into the asteroid Dimorphos on Monday (Sept. 26).
LICIACube's purpose was to witness DART's encounter with the 525-foot-wide (160 meters) asteroid moonlet Dimorphos and inspect the aftermath of the experiment, which marked the first ever attempt to alter the orbit of a celestial body. Dimorphos orbits a larger, 2,560-foot-wide (780 m) rock called Didymos, and it was the orbit of the moonlet around the parent asteroid that the DART mission intended to change. Astronomers are now observing the system to determine whether DART succeeded. The technique might one day be used to deflect a stray rock on a collision course with Earth. – Tereza Pultarova
The closest views of Europa in more than 20 years
Friday, September 30, 2022: NASA's Jupiter explorer Juno has made a close flyby of the giant planet's ice-covered moon Europa, providing the most detailed views of this strange world in more than twenty years.
This image, taken as the probe approached the moon, was shared by NASA (opens in new tab) on Twitter on Thursday, September 29, shortly after the closest pass, which took place at 5:36 a.m. EDT (0936 GMT).
During the flyby, Juno zipped at a distance of only 219 miles (352 kilometers) from Europa's surface, the third closest pass at the moon performed by any spacecraft. The last time scientists could get such an up-close glimpse of Europa, which is one of the likeliest places in the solar system to harbor primitive life, was in January 2000 when NASA's Galileo probe zoomed 218 miles (351 km) above Europa's surface. –Tereza Pultarova
Lights off in Florida after hurricane Ian's rampage
Thursday, September 28, 2022: Satellites captured darkened Florida after devastating Hurricane Ian cut power to millions of homes.
The image on the left, taken on the night of Sept. 29 by the NOAA 20 satellite operated by the U.S. National Oceanic and Atmospheric Administration, reveals the scale of the power outages that hit Florida after Ian swept across the state on Wednesday afternoon and into the night. The comparison image on the right was taken four days earlier.
The storm made landfall as an extremely dangerous Category 4 hurricane on the southwestern coast near Tampa earlier on Wednesday, and although it weakened into a 'mere' tropical storm shortly thereafter, it caused wide reaching destruction that rescue teams are only beginning to assess.
Weather forecasters warn that Ian may strengthen again as it moves northward over South Carolina, bringing torrential rains and powerful winds. – Tereza Pultarova
Hurricane Ian swirls over Gulf of Mexico ahead of Florida landfall
Wednesday, September 28, 2022: The strengthening Hurricane Ian swirls above the Gulf of Mexico in a video sequence taken by NOAA's GOES 16 satellite as it approaches Florida as a threatening Category 3 storm, forcing people to leave their homes to escape flooding and destructive winds.
Ian emerged over the Caribbean Sea over the weekend as a tropical storm and quickly grew into a hurricane before it reached Cuba on Tuesday (Sept. 27), unleashing heavy rains and sustained winds of 120 mph (192 km/h).
Ian, still gaining power over the warm waters of the Gulf of Mexico, will become a Category 4 hurricane before making landfall in Florida on Wednesday (Sept. 28) night. The storm is then expected to carve a path along the U.S. East coast, ripping through the southern states of Georgia and South Carolina. – Tereza Pultarova
Cubesat witness reveals DART asteroid impact
Tuesday, September 27, 2022: The Italian LICIACube cubesat, which traveled to the binary asteroid Didymos aboard NASA's asteroid-smashing DART mission, captured these images of DART's collision with its target space rock.
"Here are the first images taken by #LICIACube of #DARTmission impact on asteroid #Dimorphos," the LICIACube team tweeted on Tuesday (Sept. 27). "Now weeks and months of hard work are starting for scientists and technicians involved in this mission, so stay tuned because we will have a lot to tell!"
LICIACube is a 31-pound (14 kilograms) spacecraft whose sole purpose is to witness first-hand the impact and the direct aftermath of the ground-breaking DART mission. DART, for Double Asteroid Redirection Test, successfully self-destructed on Monday (Sept. 26), by slamming into the 525-foot-wide (160 m) asteroid moonlet Dimorphos in an attempt to change its orbit around the 2,560-foot-wide (780 m) parent space rock Didymos. The experiment will help NASA develop technology that could one day prevent a devastating asteroid strike on Earth. – Tereza Pultarova
Last photo of asteroid Didymos before DART impact
Monday, September 26, 2022: This may be the last picture of asteroid Didymos before its encounter with NASA's asteroid-smashing probe DART.
The dot of light in this image, captured by the Very Large Telescope (VLT) of the European Southern Observatory (ESO) in Chile on the night of September 25/26, is in fact two asteroids combined — Didymos and its smaller moonlet Dimorphos which will be the ultimate target of the collision with DART.
The VLT, one of the most powerful optical telescopes in the world, will play an important role in the observations of the DART impact aftermath. Astronomers hope the telescope will be able to provide data about the composition and motion of the material ejected from Dimorphos upon the DART crash, and make some measurements of the structure of the asteroid's surface and interior, ESO said in a statement (opens in new tab). – Tereza Pultarova
Hubble Space Telescope observes a young exploding star
Friday, September 23, 2022: The Hubble Space Telescope has captured a star surrounded by a shroud of gas created by a recent explosion.
The star, called IRAS 05506+2414, is quite young and located some 9,000 light-years from Earth in the constellation Taurus. The clouds of swirling material that surround the star were stirred up by some sort of an explosion that disrupted the young star system, NASA said in a statement (opens in new tab). The material in those clouds flows away from the star at mind-boggling speeds of 217 miles per second (350 km per second). Hubble took this image with its Wide Field Camera 3. – Tereza Pultarova
Hurricane Fiona grows into a Category 4 storm
Thursday, September 22, 2022: Hurricane Fiona, seen in this image from the European Sentinel 3 satellite, has grown into a mighty Category 4 hurricane, while it moved toward Bermuda which it is expected to skirt later today.
Fiona is the first major hurricane of the 2022 Atlantic season, which had an unusually slow start with no major storms forming above the Atlantic Ocean in the entire month of August for the first time in 25 years.
Fiona, which will stay at a safe distance from the U.S. east coast, unleashed torrential rains and powerful winds on Puerto Rico and the Dominican Republic earlier this week, causing widespread power blackouts. The hurricane will make landfall on the eastern coast of Canada this weekend as a category 2 hurricane. – Tereza Pultarova
Webb captures distant Neptune in a galaxy-studded sky
Wednesday, September 21, 2022: The James Webb Space telescope captured the solar system's most distant planet Neptune on the backdrop of a galaxy-studded sky.
The ice giant is hard to image and hasn't been observed with such clarity since the flyby of NASA's deep space mission Voyager in 1989. The planet, more than 2.7 billion miles (4.3 billion kilometers) away from Earth, is the closest object in the image, seen on the backdrop of galaxies that are billions of light-years away. – Tereza Pultarova
A striking image
Tuesday, September 20, 2022: On Sept. 12, lightning came quite close to the Artemis 1 rocket out on the launch pad at NASA's Kennedy Space Center in Florida. But the lightning didn't come from a bright blue sky, of course. This image combines NASA's footage of the strike with a "clear day frame" filter that substitutes the stormy sky with a view of the rocket under calmer weather. -Meghan Bartels

The 'Queen's' queue seen from space
Friday, September 16, 2022: The vast amount of people queuing in central London to see the coffin of the deceased British monarch, Queen Elizabeth II, can be seen in this image taken on Friday (Sept. 16) by satellites of the U.S. Earth observation firm Maxar Technologies.
The image shows the Westminster Bridge over the river Thames and the area around the iconic Houses of Parliament, where the Queen is lying in state.
According to media reports, the queue reached a length of over 5 miles (8 kilometers) on Friday afternoon, and new arrivals are currently not allowed to join. The mourners have to wait for more than 12 hours to see the Queen's coffin at Westminster Hall, which will be open round the clock until Monday morning. – Tereza Pultarova
Ancient stones emerge amid punishing drought in Spain
Thursday, September 15, 2022: An ancient monument dubbed the Spanish Stonehenge has emerged from an artificial lake for only the fourth time since the 1960s as a historic drought drained water from the reservoir.
This image of the 5,000-year-old Dolmen of Guadalperal stone circle under the stunning band of the Milky Way adorning the night sky was captured by Portuguese astrophotographer Sérgio Conceição after water levels in the the Valdecañas reservoir in the Extremadura region in western Spain dropped to only 28% of the capacity in July this year.
Conceição told Space.com that it took six hours to reach the monument for the night time shoot via a foot trail, carrying all his photographic equipment.
The monument, consisting of 150 upright granite stones, emerged amid the worst drought on the Iberian Peninsula in 1,200 years, according to Reuters. – Tereza Pultarova
Hubble sees galaxy with massive black hole at its center
Wednesday, September 14, 2022: With the attention of the world's space aficionados fixed on the endless stream of mind-blowing images beamed to Earth by the James Webb Space Telescope, the older Hubble Space Telescope might feel a little forgotten. But the 32-year-old astronomy workhorse reminds us all that it still has it, most recently with this new image of a spiral galaxy some 189 million light-years away.
The galaxy in the image is called NGC 1961, and astronomers think it has a very active super massive black hole at its center that constantly spouts highly energetic beams of material into the intergalactic space.
NGC 1961, located in the constellation Camelopardalis (near Ursa Minor), is a little less complex than our galaxy, the Milky Way, as its center doesn't feature a prominent bar of thickly packed stars, gas and dust. – Tereza Pultarova
Full moon rises above ancient castle
Tuesday, September 13, 2022: The harvest moon of 2022 rises above an ancient Portugal castle on the evening of September 10 in this image taken by a local astrophotographer.
The harvest moon, as the September full moon is called, shines bright above the Terena Castle, in the municipality of Alandroal in central Portugal, which dates back to the 13 century.
The image was captured at 10:26 p.m. local by astrophotographer Sérgio Conceição using a Canon EOS R camera with a 300mm lens. – Tereza Pultarova
Wildfires in American West seen from space
Monday, September 12, 2022: Wildfires raging on the North American west coast have been spotted by the European Earth-observing satellite Sentinel-3 this weekend.
Massive plumes of smoke rise from multiple regions where fires have erupted in the past days. In the states of Oregon and Washington, 390 square miles (1,000 square kilometers) of land have burnt so far and thousands of residents had to be evacuated. The Cedar Creek Fire, one of the largest in the region, can be seen in the image on the right. – Tereza Pultarova
Trails of Starlink satellites spoil observations of a distant star
Friday, September 9, 2022: Trails of SpaceX's Starlink satellites spoil this image of the star Albireo some 434 light-years from Earth as astronomers caution the growing number of low-Earth-orbit satellites will make observations more difficult.
The image, captured by astronomer Rafael Schmall, was released by the European Southern Observatory on Twitter (opens in new tab) on Friday, Sept. 9. The observatory, which operates some of the largest telescopes in the world, has recently released a new report (opens in new tab), which looks at the impact of mega-constellations such as Starlink on astronomical research.
ESO says wide-field surveys (such as ESO's Visible and Infrared Survey Telescope for Astronomy, VISTA, in Chile) will experience the worst effects. Up to 50% of twilight observations made by these survey telescopes can be impacted by unwanted satellite trails, ESO said. – Tereza Pultarova
Smoke trails in the wake of Ariane 5's record-breaking launch
Thursday, September 8, 2022: This image shows a trail of smoke left behind by the European Ariane 5 rocket after its launch from the European Spaceport in Kourou, French Guiana, on Wednesday (Sept. 7).
Ariane 5, Europe's reliable heavy-lift workhorse booster, blasted off from Kourou on Wednesday at 5:45 p.m. EDT (2145 GMT) into the dusk sky, painting colorful trails above the tropical landscape.
The launch, only the second for Ariane 5 this year, lofted into the geostationary transfer orbit the Eutelsat Konnect VHTS telecommunication satellite, which, with a mass of 7 tons (6.4 metric tons) and a length of 29 feet (8.8 m), is the largest ever telecommunications satellite launched by Ariane 5.
According to the launch operator Arianespace, Ariane 5, first flown successfully in 1998, only has three more launches to go before retiring. The rocket will be replaced by the newer, but considerably delayed Ariane 6. – Tereza Pultarova
Satellites capture sunken bulk carrier in Gibraltar bay
Wednesday, September 7, 2022: A European Earth-observing satellite captured this image of a partially sunken bulk carrier that collided off the coast of Gibraltar with a gas tanker last week.
The accident, which took place on Tuesday August 30, caused a leak of fuel from the damaged bulk carrier and forced the local port to close. Fuel had to be removed from the carrier before rescue operations could commence. The carrier is still stranded in the sea more than a week later. This image was taken by the Copernicus Sentinel-2 satellites on Monday (Sept. 5) – Tereza Pultarova
Michigan-based photographer captures stunning images of STEVE
Tuesday, September 6, 2022: Michigan-based photographer Isaac Diener captured this stunning image of the Strong Thermal Emission Velocity Enhancement (STEVE), an unusual form of aurora borealis, on September 5 on the Keweenaw Peninsula in Upper Michigan.
Diener, who has been photographing auroras for about seven years, said this was only the second time he had seen STEVE "that defined overhead."
"You can't predict when it's gonna happen," Diener told Space.com in an email. "It appears out of nowhere."
He added he used the same equipment and settings for his shots of STEVE as he uses to take images of the more common aurora borealis.
"I use a Fujifilm XT-3. And the lens I use is a 16mm lens," Diener said. "Settings I used on those STEVE pics are Aperture 1.4, 12 seconds, ISO 800." – Tereza Pultarova
First hurricane of this year's Atlantic season seen from space
Monday, September 5, 2022: The European Earth-observing satellite Sentinel 3 photographed hurricane Danielle, which formed in the Atlantic Ocean after an unusually quiet period.
For the first time in 25 years, no tropical storm arose from the Atlantic Ocean in the month of August, according to the U.S. National Oceanic and Atmospheric Administration (NOAA). Danielle, which broke the quiet spell when it formed from moisture above the central Atlantic on Thursday (Sept. 1), is not threatening the U.S. coast as Atlantic hurricanes usually do, but is instead tracking eastwards toward Europe.
AccuWeather predicts that Danielle, currently a category 1 hurricane will weaken and disintegrate before reaching the south of the U.K. and the western coast of France this weekend. Sentinel 3 took this image on Sunday (Sept. 4). – Tereza Pultarova

The view displays the crater's characteristic circular shape; this crater currently contains a crescent-shaped lake where a river flows into the impact scar. —Meghan Bartels
Betelgeuse recovering after mysterious dimming episode
Friday, Aug. 12, 2022: Betelgeuse underwent a strange dimming event in 2019. Now scientists looking at data from the Hubble Space Telescope and several other observatories believe the red giant star blew its top in 2019, and that Betelgeuse's behavior is still somewhat temperamental as a result.
Astronomers put together a timeline of the events showing that the star likely had a huge surface mass ejection. That event made a huge area of Betelgeuse blast off into space. The outburst was 400 billion times more massive than a typical coronal mass ejection that the sun experiences. — Elizabeth Howell
NASA 'moonikin' readies for Artemis 1 launch
Thursday, Aug. 11, 2022: The German space agency caught a glimpse of a NASA 'moonikin' during final preparations for a lunar mission.

NASA initially planned to use xEMU in support of its Artemis program, which aims to put boots on the surface no earlier than 2025. Earlier this year, however, the agency asked commercial companies to manufacture Artemis spacesuits after the NASA Office of the Inspector General raised concerns about development delays with the xEMU. The companies making lunar spacesuits will have access to xEMU data during development of their own astronaut outfits. — Elizabeth Howell
'Celestial cloudscape' shines in Orion Nebula
Monday, Aug. 8, 2022: A new image from the Hubble Space Telescope appears to be peering into the depths of a watercolor cloud. The "celestial cloudscape", as European Space Agency officials termed it (opens in new tab), is in reality a swirl of gas surrounding a star nursery in the famed Orion Nebula.
Hubble was capturing activity around Herbig Haro (HH) object 505. HH objects are glowing areas around fresh stars, which occur as winds flowing off from these newborns slams swiftly. into regional gas and dust.
"In the case of HH 505, these outflows originate from the star IX Ori, which lies on the outskirts of the Orion Nebula around 1000 light-years from Earth," Hubble officials added. "The outflows themselves are visible as gracefully curving structures at the top and bottom of this image, and are distorted into sinuous curves by their interaction with the large-scale flow of gas and dust from the core of the Orion Nebula." – Elizabeth Howell
Water level so low in Europe's Rhine river that cargo ships may no longer be able to pass
Friday, August 5, 2022: The prolonged spell of hot and dry weather that affects Europe this summer has caused the water level in the river Rhine, one of western Europe's major waterways, to drop so low that cargo ships may no longer be able to pass.
