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.
NASA previously scrapped launch attempts in August and September due to ongoing problems with hydrogen leaks. – Tereza Pultarova
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

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
A glimpse of Greece

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 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

Monster Typhoon Hinnamnor threatens Japan
Thursday, September 1, 2022: A mega-typhoon that formed in the Eastern Pacific Ocean brings destructive winds and flooding into southern Japan and South Korea.
The typhoon, named Hinnamnor, is the most powerful tropical storm of the 2022 typhoon season. In this image, taken by the European Earth-observing satellite Sentinel 3 on Wednesday (Aug. 31), the typhoon covers a large portion of the 745-mile-wide (1,200 kilometers) shot.
Forecasters predict wind gusts of up to 185 mph (300 km/h), threatening widespread damage to infrastructure, according to AccuWeather.
The northern summer of 2022 has been full of extremes with record drought and heat waves plaguing most of Europe and extreme floods ripping through Pakistan and parts of the U.S. The Atlantic hurricane season, on the other hand, has been extremely quiet, producing no hurricanes in the month of August, a first in 25 years, according to Bloomberg.-- Tereza Pultarova
Jupiter's clouds revealed in true colors in new Juno image
Wednesday, August 31, 2022: This new image captured by NASA's Juno Jupiter explorer reveals features in the turbulent atmosphere of the solar system's largest planet in the same colors a human observer would see them.
Juno took the image on July 5, 2022, during its 43rd close flyby of Jupiter using its JunoCam instrument. The spacecraft was at a distance of 3,300 miles (5,300 kilometers) from the tops of the gas giant's clouds when the image was taken, zipping by at 130,000 mph (209,000 kilometers per hour).
Citizen scientist Björn Jónsson processed the raw data from Juno to create two images. The image on the left hand side shows the view as it would appear to a human observer in Juno's position. In the image on the right, Jónsson digitally enhanced color saturation and contrast, allowing the intricate structure of the planet's atmosphere to come to the fore. – Tereza Pultarova

Amazing auroras entertain astronauts aboard the International Space Station
Monday, Aug. 22, 2022: ESA astronaut Samantha Cristoforetti shared incredible images of auroras seen from the International Space Station.
In a tweet posted Sunday, Aug. 21, Cristoforetti wrote (opens in new tab) "The sun has been really active lately. Last week we saw the most stunning auroras I have ever experienced in over 300 days in space!"
In the image, the space station can be seen silhouetted against spiraling bright green auroras dancing across the Earth's upper atmosphere. A high number of sunspots on the sun's surface have been generating solar flares and coronal mass ejections in recent months, suggesting the sun is entering a more active phase of its regular 11-year-cycle. — Brett Tingley
Hubble reveals scintillating globular cluster on the Milky Way's heart
Friday, Aug. 19, 2022: The Hubble Space Telescope photographed a glittering stellar cluster at the heart of our galaxy, the Milky Way, which could help astronomers unravel some of the mysteries of the galaxy's past.
The globular cluster called NGC 6540 is located about 17,000 light-years away from Earth toward the center of the Milky Way and consists of thousands of stars packed tightly by their gravitational attraction.
The cluster, which can be found in the night sky in the constellation Sagittarius, could help astronomers learn more about the Milky Way's past. Globular clusters are very old and by measuring their ages, shapes and structures, astronomers get a glimpse of how galaxies evolve. – Tereza Pultarova
Stunning auroras brighten up view from space station
Thursday, Aug. 18, 2022: With the increased activity of the sun over the past week, astronauts on the International Space Station get treated to spectacular views of polar light displays above the planet.
This image, shared on Twitter (opens in new tab) by NASA astronaut Bob Hines on Wednesday (Aug. 17), coincides with the arrival of a coronal mass ejection, a burst of plasma from the sun, which triggered a geomagnetic storm in Earth's atmosphere.
"Absolutely SPECTACULAR aurora today!!! Thankful for the recent solar activity resulting in these wonderful sights!," Hines said in his Tweet.
While Earthling's won't be able to enjoy such magnificent spectacles, auroras can currently be spotted from areas farther away from the poles than usual. In the U.S., these natural light displays might brighten up the sky as far south as New York, and the northern parts of Europe can get a glimpse too. – Tereza Pultarova

A different kind of crater lake
Monday, Aug. 15, 2022: ESA astronaut Samantha Cristoforetti has one of the best views of our planet from her perch on the International Space Station, and in a tweet posted Thursday (Aug. 11), she shared the view with the people of Chad to celebrate the nation's independence day.
"We explore space, and sometimes space comes to us," she wrote (opens in new tab) introducing an image of the Gweni-Fada meteorite impact crater, which she noted is about 9 miles (14 kilometers) across and formed more than 300 million years ago. 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. While DLR was loading some mannequins on board Artemis 1, engineers uploaded an image of the NASA human simulant, who is named after Apollo 13 engineer Arturo Campos.
"Our #LunaTwins have taken their places. This past week, Helga & Zohar have been assembled & installed in the capsule at . Waiting inside to greet them – Commander Moonikin Campos who is also one of the ‘passengers’ on board #Artemis I," DLR tweeted (opens in new tab).
Artemis 1 aims to launch no earlier than Aug. 29 for a round-the-moon mission that will last more than a month. The mission will use these mannequins to assess the space environment for radiation, shaking and other stresses of spaceflight to make sure the Space Launch System rocket and Orion spacecraft are ready to carry humans later in the 2020s. — Elizabeth Howell
SpaceX does a static fire test for Starship rocket
Wednesday, Aug. 10, 2022: SpaceX is getting ready for its first orbital flight of Starship. SpaceX conducted a "static fire" test of its Starship Super Heavy Booster 7 on Aug. 9, 2022 at its launching facility in south Texas.
"Team at Starbase completed a single Raptor engine static fire test of Super Heavy Booster 7 on the orbital launch pad," SpaceX wrote in a tweet describing the test.
SpaceX will need to secure full approval from the Federal Aviation Administration before making the launch, which will be Starship's first in orbit and the first mission of any sort since 2021. SpaceX hopes to make that journey later in 2022 to prepare Starship for NASA human Artemis program missions to the moon and eventually, human Mars exploration. — Elizabeth Howell
NASA astronauts train with xEMU lunar spacesuit
Tuesday, Aug. 9, 2022: NASA astronaut Don Pettit shared an image of he and fellow agency astronaut Doug Wheelock, each wearing an xEMU spacesuit prototype. The NASA spacesuit is being assessed at the agency's Kennedy Space Center in Florida, Pettit wrote, for its ability to support astronaut activities on the moon.
"Learning how to clean our spacesuits before ingressing the lander," Pettit wrote on Twitter (opens in new tab). "Everyone wore full face respirators. Lunar regolith has health implications to crewed #artemis missions."
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.
A comparison of two images captured by the European Earth-observing satellite Sentinel-2 a year apart, on Aug.5 2021 and Aug. 3 2022, reveals the severity of the situation near the city of Gendt in the Netherlands.

The pair also hand deployed several small satellites.
The milestone spacewalk took place amid tensions between Russia and its western partners over Russia's invasion of Ukraine. Earlier this month, the Russian space agency Roscosmos released images of the current Russian space station crew posing with flags of the separatist regions in eastern Ukraine where Russian military forces killed thousands of civilians in the past months. – Tereza Pultarova
Details of intricate Martian canyon system revealed in a new image
Thursday, July 21, 2022: The European Mars Express spacecraft captured an image revealing massive ruptures in Martian crust that form part of the 2,500-mile-long (4,000 kilometers) Valles Marineris canyon system.
The image, captured on Apr. 21 but only released by the European Space Agency (ESA) on Jul. 20, shows the Ius and Tithonium Chasmata, or trenches, in the western part of the Valles Marineris. Ius Chasma, on the left, is 522 miles long (840 km), while the Tithonium Chasma, on the right, stretches over 500 miles (805 km). At 4.4 miles deep (7 km), the trenches could nearly swallow Earth's highest mountain Mount Everest.
Valles Marines is the largest canyon system in the solar system. If put on Earth, it would stretch from the north of Norway all the way to Sicily in the south of Italy. The canyon system is ten times longer, 20 times wider and five times deeper than the U.S. Grand Canyon. – Tereza Pultarova
Satellite captures cloudfree Europe amid sweltering heat wave
Wednesday, July 20, 2022: The European weather forecasting satellite Meteosat observed as the nearly cloud-free Europe broiled in a record-breaking July heatwave.
The video, capturing views of Europe from 22,000 miles (36,000 kilometers) afar during the past two weeks, reveals a high pressure ridge over north-west Africa, funneling hot air into western Europe.
This ridge kept low pressure systems at bay, preventing build up of clouds and rain, the European Organization for the Exploitation of Meteorological Satellites (EUMETSAT), which operates the Meteosat satellite, said in a statement. (opens in new tab)
The heatwave broke temperature records in several countries including Portugal, which reached an all time high of 116 degrees Fahrenheit (47 degrees Celsius) and the usually cooler U.K., which for the first time in recorded history saw temperatures exceed 105 degrees F (40 degrees C). – Tereza Pultarova

According to the European environmental agency Copernicus, over 150 square miles (390 square kilometers) of land have burnt in the past ten days in France, Spain and Portugal alone.
The highest alert for the risk of wildfire breakouts is in place today in Spain, France, Italy and the U.K. – Tereza Pultarova
Hubble captures illusory mirror galaxies through gravitational lens
Monday, July 18, 2022: The mirror galaxy at the center of this image is a mirage caused by a phenomenon called gravitational lensing, in which a super-massive object bends light, acting like a magnifying glass.
The image, obtained by the Hubble Space Telescope, captures a galaxy called SGAS J143845+145407, which sits behind a massive object that causes the lensing effect.
Gravitational lensing is nature's help for astronomers, enabling them to observe stars and galaxies that would otherwise be too distant and faint to see. The image was obtained during a campaign focused on the oldest galaxies in the universe, and scientists hope it will help them piece together how first galaxies emerged in the early universe. – Tereza Pultarova
Europe's Vega C rocket lifts off for its debut flight into the cloudy South American sky
Friday, July 15, 2022: The European Vega C rocket is captured in this image seconds after lifting off for its debut flight on Wednesday, July 13.
The European Space Agency, which oversaw the development of Vega C, shared the image on its Twitter account, saying: "We love this shot from one of ESA photographer Stephane Corvaja's remote cams! @vega_sts lit up the rainy gray skies of Kourou earlier this week."
The rocket, which shot off from the European spaceport in Kourou, French Guiana, after a two-hour delay, is an enhanced version of the earlier Vega and can lift larger and heavier payloads compared to its predecessor.
Vega C is expected to play an important role in helping Europe plug the gap in its access to launch services that it struggles with after having ceased cooperation with Russia in the wake of the invasion of Ukraine. The French company Arianespace, which manages the European launcher program, used to offer launches on Russia's Soyuz rockets in addition to the European homegrown Vega and the heavy lift Ariane 5. But Russia terminated the cooperation as a retaliation for sanctions imposed by western countries in response to the situation in Ukraine. – Tereza Pultarova

The faintest ever asteroid observed by Very Large Telescope
Wednesday, June 29, 2022: The Very Large Telescope in Chile managed to track an extremely faint asteroid to help rule out its projected collision with Earth.
The asteroid, dubbed 2021 QM1, was discovered in August last year. Initial observations indicated it was bound to slam into our planet in 2052. The asteroid then disappeared for several months in the glare of the sun as it approached the star. When it reemerged in the darker sky again, it was too far away for most ground-based telescopes to see. But the European Southern Observatory's Very Large Telescope in Chile, one of the most powerful optical telescopes in the world, rose to the challenge and detected the asteroid when it had a magnitude of 27 (the sun, by far the brightest object in the sky, has a magnitude of minus 27). On top of that, astronomers had to find the super-faint space rock on the backdrop of the star-studded band of the Milky Way. The observations enabled astronomers to finetune the calculation of the space rock's orbit and confirm it won't hit Earth in the end. – Tereza Pultarova
Goodbye to Cygnus
Tuesday, June 28, 2022: European astronaut Samantha Cristoforetti posing at the hatch between the International Space Station and the Cygnus cargo vehicle, which is expected to depart on Tuesday (June 28).
The image, taken just before the closing of the hatches, reveals the Cygnus interior packed with waste and unwanted items, which the capsule will take with it for a burn-up in Earth's atmosphere.
"Last night on ISS for Cygnus!" Cristoforetti wrote in a tweet. "Vehicle is fully loaded, hatch is closed, robotic arm has grappled it for unberthing early tomorrow morning. Thanks for bringing us supplies, for the orbit reboost and…. last but not least… for taking our trash!"
Cygnus, developed by American firm Orbital Sciences, which was since acquired by aerospace giant Northrop Grumman, is not designed to return to Earth, unlike SpaceX Cargo Dragon capsule.
During its mission, Cygnus performed its first reboost of the International Space Station's altitude. The maneuver, completed on Saturday (June 25), was only partially successful and raised the station's altitude by one tenth of a mile, NASA said in a statement. Cygnus previously tested the capability in 2018. – Tereza Pultarova

Mercury dazzles in a new snap by Europe's BepiColombo probe
Thursday, June 23, 2022: The BepiColombo space probe took its second look at Mercury on Thursday, June 23, during a gravity-assist flyby designed to adjust the spacecraft's trajectory so that it can enter orbit around the solar system's innermost planet in 2025.
BepiColombo, a joint mission between the European Space Agency (ESA) and the Japan Aerospace Exploration Agency (JAXA), launched in 2018 for a seven-year cruise to the scorched little planet.
Mercury is notoriously difficult to reach as any spacecraft traveling in its direction needs to constantly brake against the gravitational pull of the sun. To do that, mission specialists designed a trajectory that takes the spacecraft on a long and winding road, which uses the gravity of other celestial bodies to slow down the spacecraft. BepiColombo has to perform nine flybys overall before it can enter the orbit of Mercury: one at Earth, two at Venus and six at Mercury itself. This image was taken during BepiColombo's second encounter with Mercury, when the probe passed only about 120 miles (200 km) above the planet's crater-riddled surface. – Tereza Pultarova
Traces of past flooding spotted on surface of Mars
Wednesday, June 22, 2022: This image captures the Hebrus Valles channels in the northern lowlands of Mars, which were likely created by a catastrophic flooding in the past.

Astronauts watch Etna volcano eruption from space
Tuesday, June 07, 2022: Italy's volcano Mount Etna has been spewing out lava in the past weeks and astronauts have enjoyed the spectacle from the International Space Station.
Italian astronaut Samantha Cristoforetti shared this image of the fuming Etna on her Twitter account on Sunday (June 5).
"Mt. Etna still erupting today, while the sun glint turned the sea into a pool of silver," Cristoforetti said in the tweet (opens in new tab).
Etna is Europe's most active volcano, but fortunately, its slow-burning eruptions have killed only 77 people in the past 2,700 years, according to the Royal Geographical Society. (opens in new tab)
The current eruption is no different. No damage to property or evacuations have been reported. – Tereza Pultarova
NASA's moon rocket heading to launch pad for major test
Colors of the wind
Monday, June 06, 2022: NASA's Space Launch System rocket is being rolled out to the launch pad for another go at the wet dress rehearsal test after a scrapped attempt in April due to fuelling problems.
The rocket, with the Orion capsule on top, began its four-mile journey from the iconic, Apollo-era Vehicle Assembly Building to Launch Complex 39B on Monday (June 6) at 12:01 a.m. EDT (0401 GMT).
The rocket, which is expected to launch the Orion capsule for an unmanned test flight to the moon and back later this year, is set for the next wet dress rehearsal attempt in late June. During the wet dress rehearsal, the engineering teams will simulate the entire pre-launch procedure including fuelling and countdown, minus only the launch itself. – Tereza Pultarova
June 3, 2022: Inspiration4 astronaut Haley Arceneaux showed off the Pride flag in a tweet (opens in new tab) Wednesday (June 1), taken during her three-day mission in September 2021. "Happy Pride Month to all who celebrate and all who support," Arceneaux wrote. "I took this photo in space as we were passing over a sunset. It's like the earth was celebrating by showing off these beautiful colors."

Stacking the space shuttle
Thursday, June 2, 2022: A forthcoming museum launch exhibit will show off how the space shuttle used to look on the launch pad. The California Science Center broke ground Wednesday (June 1) for its Samuel Oschin Air and Space Center, the new permanent home (opens in new tab) of NASA's retired space shuttle, Endeavour. After 10 years of horizontal display, the spacecraft will eventually be repositioned to stand vertically alongside an external tank and twin solid rocket boosters in its liftoff position. Standing underneath the exhibit will simulate what only a few individuals used to see up close, during pad preparations to send Endeavour into space. — Elizabeth Howell
Feeling blue: The difference between Uranus and Neptune's colors is hazy
Wednesday, June 1, 2022: Now we might know why Neptune is a deeper blue in the face than Uranus. It comes down to a deep atmospheric layer that is full of haze. Neptune tends to recycle methane particles more quickly than Uranus in that middle layer, so the haze builds up on Uranus and turns it whiter. We might get lucky enough to take a closer look in a few decades, since a new government document suggests a Uranus mission should be NASA's highest-priority large planetary science mission and launch in the 2030s. — Elizabeth Howell
A bright shooting star shines above Red Planet-like rock
Tuesday, May 31, 2022: This image of a tau Herculids meteor looks like it belongs on Mars, but it actually was taken from a ruddy area of Nevada. The shooting star was captured May 30 from the Valley of Fire State Park as Earth ran into numerous shards from comet 73P/Schwassmann-Wachmann, or SW3. There was no storm of shooting stars as some had hoped, but many meteor watchers around the world caught bright streakers like this one. — Elizabeth Howell
Stunning South Pole lunar eclipse on the aurora backdrop
Friday, May 27, 2022: This stunning time-lapse photograph shows the May 15 total lunar eclipse above an astronomical observatory at the South Pole on the backdrop of magnificent auroras and the star-studded polar sky.
The picture was taken by Aman Chokshi, a PhD astronomy student at the University of Melbourne, Australia, who is currently spending a year working at the South Pole Telescope in Antarctica, which studies microwave radiation emitted by the cosmos as part of the black-hole watching Event Horizon Telescope network.
"Last Monday we were lucky to see a total lunar eclipse from the South Pole," Chokshi told Space.com in an email. "The moon gradually dimmed and turned orange. It was crazy to see how the sky dimmed and the millions of stars of our Milky Way galaxy emerged. At the peak of the eclipse, a band of glowing auroras surged across the sky. A truly spectacular evening!"
Chokshi (whom you can see in the picture together with a friend waving into the camera from the edge of the roof of the telescope building), took the images that make up this time lapse over a 5-hour period.
"The background image is a single 20-second exposure with a sigma 24-70 millimeter lens, at f/2.8, iso 3200 on a Sony A7RVI, captured at the peak of the eclipse," Chokshi said. "The array of moon images were captured with an old sigma 400mm film lens, on a Sony A7S, on a skywatcher star adventurer tracker. The final composite image contains images of the moon every four minutes."
It took some courage and resourcefulness for Chokshi to take the images. The South Pole, currently nearing the peak of the winter period, is submerged in permanent darkness, and the polar expeditioners have to put up with some of the most extreme weather conditions one can experience on Earth.
"We had a sustained wind of 15-20 knots, which brought the ambient temperature of minus 60 degrees Celsius [minus 76 degrees Fahrenheit] to minus 80 degrees C [minus 112 degrees F] with windchill," Chokshi said. "Both cameras had to be housed in special heated foam boxes which I made, to prevent them from freezing."

Starliner lands safely, concluding a successful delayed test flight
Thursday, May 26, 2022: Boeing's Starliner space capsule has safely touched down at a missile range in New Mexico, concluding a successful, although more than a year delayed, test flight.
Starliner, which is set to join SpaceX's Crew Dragon in ferrying astronauts to and from the International Space Station, spent five days docked at the orbital outpost running through a series of tests.
The capsule launched on May 19 atop United Launch Alliance's Atlas V Rocket from Cape Canaveral in Florida. The test flight was Boeing's second uncrewed attempt to demonstrate the performance of the technology, after its first orbital test flight failed to reach the space station in December 2019 due to software glitches. The capsule may perform its first flight with astronauts by the end of this year. – Tereza Pultarova

InSight Mars lander's death by dust
Tuesday, May 24, 2022: NASA's InSight Mars lander is slowly losing its battle against the dust, which has accumulated on its solar panels, preventing the spacecraft from generating the energy it needs to continue science operations.
This animation compares the state of InSight's solar panels in December 2018, shortly after its arrival to the red planet, and on April 24, 2022, after 1,211th Martian days. In a Twitter post (opens in new tab), NASA described the second image as InSight's "final selfie".
Because of the dust cover, it has been increasingly difficult to keep InSight going and it is likely that NASA will kill the mission completely in the very near future.
The robotic arm, which was used to take those images, is expected to be put into a "retirement position" by the end of May, NASA said in a statement (opens in new tab), because the solar panels no longer produce enough electricity to make it move. – Tereza Pultarova
Boeing's Starliner spaceship docked at International Space Station
Monday, May 23, 2022: After years of delays and one failed attempt, Boeing's Starliner space taxi has finally reached the International Space Station during its second unmanned orbital test flight.

This picture was taken by European astronaut Samantha Cristoforetti shortly after the docking. Later, NASA astronaut and Cristoforetti's crew mate Kjell Lindgren commented on the picture (opens in new tab)on Twitter: "It's been a busy and amazing 3 weeks. So excited to be back in orbit with Exp67 and to welcome Boeing #Starliner to the International Space Station."
Starliner is expected to remain at the International Space Station until the middle of this week. It will perform a series of orbital tests before returning to Earth when weather permits. – Tereza Pultarova
Boeing's Starliner on its way to International Space Station
Friday, May 20, 2022: Boeing's Starliner capsule finally lifted off for its second test flight to the International Space Station after many months of delays.
The capsule, designed to carry astronauts to the orbital outpost, launched atop a United Launch Alliance Atlas V rocket from Cape Canaveral Space Force Station in Florida at 6:54 p.m. EDT (2254 GMT) on Thursday (May 19).
The flight, the Orbital Flight Test 2 (OFT-2), is Boeing's second uncrewed demonstration after Orbital Flight Test 1, which failed to reach the space station in December 2019.
The mission was originally scheduled for last summer but was postponed due to issues with the capsule's propulsion system. – Tereza Pultarova
Astronaut's spine after six months in space
Thursday, May 19, 2022: NASA astronaut Raja Chari shared this image of his spine as he is recovering after six months on the International Space Station.
Chari, who was a member of the Crew-3 mission, which returned to Earth on May 5 on board of SpaceX's Crew Dragon capsule, shared the image on Twitter (opens in new tab) together with other images of him being subject to various tests in order to evaluate the state of this body after his orbital mission.
"Science continues after @NASA_Astronauts return from @Space_Station," he said. "For months #Crew3 will gather data for human research experiments to compare to in-flight. Our brain & vestibular system are nearly back to normal, but it’ll take months to get muscles & bones back to normal."
In the absence of gravity, astronauts' muscles and bones weaken in spite of the rigorous exercise regime that the spacefarers follow. This physical deterioration is one of the biggest obstacles for long-term human presence in space. Studies by NASA (opens in new tab)suggest that it may take more than a year for the bones to regain their former strength. – Tereza Pultarova
Sun's poles photographed in greatest detail ever
Wednesday, May 18, 2022: The European Solar Orbiter spacecraft captured the closest ever images of the sun's south pole, an area responsible for the generation of the star's magnetic field.
The image was taken during Solar Orbiter's closest pass at the sun on March 26. At that point, the spacecraft, fitted with ten scientific instruments, approached the star at the center of our solar system as close as one third of the sun-Earth distance.
Studying the sun's poles is one of the main tasks of Solar Orbiter. Polar regions are believed to play a key role in the generation of the sun's magnetic field, which drives its 11-year-long cycle of activity, the periodic ebb and flow in the generation of sunspots, solar flares and eruptions. – Tereza Pultarova
Saharan dust storm heading to America
Tuesday, May 17, 2022: A massive cloud of dust swept up by winds over the Saharan desert has been photographed by European satellites as it moves over the Atlantic Ocean towards the Caribbean.

Years-long imaging campaign reveals Milky Way's central black hole
Friday, May 13, 2022: The supermassive black hole at the center of our galaxy, the Milky Way, can be seen in this image taken by the Event Horizon Telescope as part of a ground-breaking campaign.
Scientists have known for decades that there is a strange source of radio waves, known as Sagittarius A*, at the center of our galaxy. Over the years, more and more evidence has been gathered that this source must be a supermassive black hole. Any residual doubt has now been removed when the worldwide Event Horizon Telescope partnership succeeded to take the first ever photograph of this strange source, revealing a characteristic shadowy center surrounded by a glowing disk of material falling into the black hole.
The image of Sagittarius A* is only the second image of a black hole ever taken, the first being that of the much larger black hole at the center of the galaxy M87, which was released in 2019. – Tereza Pultarova

First made-in-Europe micro launcher unveiled
Wednesday, May 11, 2022: A British rocket company Orbex has unveiled a prototype of its reusable micro-rocket Prime as it prepares for its debut flight later this year.
Prime is the first of Europe's micro launcher developments to achieve this stage. Designed to take into orbit satellites of up to 440 lbs (200 kilograms), the rocket uses renewable fuel biopropane, which slashes the carbon footprint of each launch by over 90% compared to equivalent rockets relying on fossil fuels.
Orbex will launch its rockets from Space Hub Sutherland, a new spaceport in the north of Scotland. It plans to fly Prime for the first time by early 2023 in what it hopes will be the first vertical launch from U.K. soil. However, other companies are working on their rockets as well and have plans to launch soon. – Tereza Pultarova

Partial solar eclipse above Chile's Atacama Desert
Monday, May 9, 2022: A partial solar eclipse above the Atacama Desert in Chile provided a fascinating spectacle to sky-watchers at the popular astronomy destination.
This photograph was taken by the European Southern Observatory (ESO) photographer Pavel Horálek on April 30 near San Pedro de Atacama above the Moon Valley, a popular tourist spot featuring lunar-like landscapes.
The photo shows a sequence of images capturing the progress of a partial solar eclipse, caused by the moon obscuring a fraction of the sun's disk. The sequence was taken over a period of 54 minutes just as the sun was about to set, ESO said in a statement.
The dusty glow of the image is caused by volcanic ash from the Hunga Tonga volcano, which erupted in January this year in the Southern Pacific Ocean. The ash, ESO said in the statement, remains suspended in the atmosphere nearly four months after the eruption. – Tereza Pultarova

The rover captured the early morning snapshot using its robotic arm-mounted Instrument Deployment Camera (IDC) at about 5:30 am, just as the sun was climbing above the horizon, the lander team said on its website.
"I’ll never tire of sunrise on Mars," the mission team said on Twitter. "Each morning, that distant dot climbs higher in the sky, giving me energy for another round of listening to the rumbles beneath my feet."
InSight investigates the geology of Mars including its seismology. The lander has made headlines by detecting Martian earthquakes.– Tereza Pultarova
Hubble spots largest comet ever
Tuesday, April 12, 2022: The Hubble Space Telescope has spotted the largest comet ever, a hundred thousand times greater than the average comet in the solar system.
Hubble photographed comet C/2014 UN271 (Bernardinelli-Bernstein) in January this year at a distance of 2 billion miles (3.2 billion kilometers). At such a distance, scientists couldn't directly see the comet's nucleus, but had to process the images to subtract the comet's bright tail.
They found that Bernardinelli-Bernstein was 85 miles (137 km) across, which is 50 times larger than nuclei found in the vast majority of all known comets. The comet's mass is around 500 trillion tons (454 million metric tonnes), a hundred thousand times greater than the mass of a typical comet orbiting the sun. – Tereza Pultarova
Hubble peers inside distant galaxy to see how stars form
Monday, April 11, 2022: The Hubble Space Telescope snapped this image of a distant galaxy to see stars arising from clouds of gas.
The galaxy, called Messier 91, or M91, is quite similar to our own Milky Way. Some 55 million light-years away from Earth, M91 is a spiral galaxy with a bar of thickly packed stars, dust and gas running across its center. Inside this bar lurks a supermassive blackhole that astronomers previously managed to weigh using earlier Hubble observations (that measurement, however, was rather rough, giving the black hole's mass as somewhere between 9.6 and 38 million masses of our sun).
This newly released image captures the galaxy, which is located in the constellation Coma Berenices, in ultraviolet and visible light. – Tereza Pultarova
First American civilian mission to space station launches

They will join the current crew of three NASA astronauts (Raja Chari, Kayla Barron and Thomas Marshburn), German astronaut Matthias Maurer and three Russian cosmonauts (Sergey Korsakov, Oleg Artemyev and Denis Matveev). – Tereza Pultarova
Milestone missions side by side at NASA's spaceport
Thursday, April 7, 2022: NASA's Space Launch System (SLS) moon rocket and SpaceX Falcon 9, which will launch the first U.S. civilian mission to the International Space Station later this week, stand ready on their launchpads at NASA's Kennedy Space Center in Florida.
NASA shared the image on Twitter, saying this was the first time "two different types of rockets & spacecraft made to carry humans are on the sister pads at the same time."
While SpaceX's Falcon 9 is scheduled to launch the Axiom 1 mission to the International Space Station on Friday (April 8). The SLS rocket is currently waiting for its wet dress rehearsal on launchpad 39B. The wet dress rehearsal is the final pre-launch test designed to take the rocket through the entire pre-launch sequence including countdown. The test was halted earlier this week due to problems with the mobile launcher platform. SLS is expected to lift off for the unmanned Artemis I technology demonstration mission later this year. –Tereza Pultarova
Astronomer snaps newly discovered asteroid zooming past Earth
Wednesday, April 6, 2022: An Italian astronomer snapped this image of the 24 to 52 feet (7.2 to16 meters) wide asteroid 2022 GN1 as it zoomed past our planet at about one third of the Earth-moon distance on Wednesday (April 6).
The asteroid, discovered only on Friday (April 1), was never thought to pose any danger to Earth. As predicted, the space rock passed 86,370 miles (139.000 kilometers) from Earth's surface on Wednesday, enticing observers and astrophotographers.
This image, taken about 75 minutes before the asteroid's closest approach, is a result of a 30-second exposure taken remotely by a robotic telescope located in Ceccano, Italy, about 55 miles (90 km) from Rome.
Gianluca Masi, who operates the telescope, said in a statement (opens in new tab)that the telescope tracked the moving asteroid, which appears as a small dot at the center of the image, with the surrounding stars appearing like long trails. – Tereza Pultarova
Meteor camera reveals scope of satellite pollution
Tuesday, April 5, 2022: A camera looking for falling stars captured a jumble of satellite trails in one of its worst ever nights of satellite pollution.
The camera, located in North Oxfordshire, England, is operated by the UK Meteor Network. In the image, released on Twitter by the camera's owner, skywatcher and science communicator Mary McIntyre, star trails can be seen as curved lines and aircraft trails as dotted lines. The rest are streaks left behind by passing satellites. In the hodgepodge, one can find about 25 meteor streaks.
"Overnight on 2nd3rd April 2022 our southwest facing #RaspberryPi #meteorcamera UK0006 based in North Oxfordshire had one of the worst nights we've ever seen for #satellitetrails," McIntyre said in the tweet. "Just horrendous :("
Meteor cameras survey large portions of the sky in a relatively low resolution, looking for sudden bright streaks caused by space rocks passing through Earth's atmosphere. The long-exposure shots reveal the tracks of everything else that passes through the sky in the given night.
Satellite trails have become a major concern for astronomers especially since SpaceX started launching its Starlink satellite megaconstellation. The trails obscure the view of distant stars and brighten the night sky, making observations more difficult. The problem affects even some of the most pristine locations such as Chile's Atacama Desert. – Tereza Pultarova
Lightning strikes support tower as NASA's moon rocket prepares for test
Monday, April 4, 2022: Four lighting bolts struck the umbilical tower of NASA's Space Launch System rocket on Saturday (April 2) as the powerful booster was being prepared for tests on the launch pad at NASA's Kennedy Space Center in Florida ahead of its debut moon-bound flight later this year. The eerie images were captured on camera by a NASA TV crew.
The 322 feet (98 meters) mega rocket will blast off toward the moon later this year for the uncrewed Artemis I mission, which will serve as a technology demonstration before the first flight with astronauts. The first crewed mission is currently scheduled for 2024.
Three of the strikes, which zapped tower two, were low intensity, NASA said in a statement. The fourth, a higher intensity bolt, struck tower one.
The rocket was rolled out on the launch pad two weeks ago in preparation for its wet dress rehearsal, a final test, during which engineers will fuel the rocket and run it through the entire pre-launch sequence including the countdown.
The engineers, however, decided to halt the tests on Sunday due to problems with fans that maintain pressure in the mobile launcher platform. – Tereza Pultarova
Mesmerizing aurora glows over rural Saskatchewan
Friday, April 1, 2022: This breathtaking view of glowing auroras over the Canadian province of Saskatchewan was captured by nature photographer Jenny Hagan (opens in new tab) on Wednesday (March 30) after two coronal mass ejections triggered a geomagnetic storm that reinvigorated Earth's polar lights displays.
Jenny, from Eatonia in West Central Saskatchewan, used her Canon 80D camera on a tripod, shooting at 3 second intervals to capture the "lively night sky dancing above me".
"Sights like these are plentiful here in rural Saskatchewan," she told Space.com. "The land of the living sky, and the relics of the past offer up great foreground for the wide open views of our sky. Sitting millions of miles away from us, space modules, satellites, and stars contribute to the light that breaks through the dark."
The mysterious building in the picture is an abandoned 1950s farmhouse near the tiny village of LaPorte, Jenny added. – Tereza Pultarova
Satellite spots aurora in black and white from orbit
Thursday, March 31, 2022: An American weather satellite spotted swirling aurora displays above the North Pole after two coronal mass ejections hit Earth on Thursday early morning, triggering a strong geomagnetic storm.
The satellite that captured this image is the polar orbiting NOAA-20 operated by the U.S. National Oceanic and Atmospheric Administration (NOAA), which circles the Earth from pole to pole seven times a day.
It acquired the image on Thursday morning at 2:57am EDT (0657) GMT as it flew over the U.S. Atlantic coast.
Skywatchers on Earth could observe the auroras from most of Canada. In the U.S., sightings as far south as Colorado have been reported. Auroras are usually visible only above polar regions, but strong geomagnetic storms triggered by coronal mass ejections, which frequently accompany solar flares, temporarily intensify the phenomena, making them visible from farther afield. Good aurora viewing conditions are expected to continue until at least Friday (April 1). – Tereza Pultarova
Brain terrain in Mars' largest impact basin
Wednesday, March 30, 2022: Strange structures resembling the human brain have been spotted by the European Mars Express orbiter in the Red Planet's largest impact basin.
The image, captured by the 18-year-old spacecraft in July 2021, reveals two craters surrounded by darkened warped terrain that somewhat resembles the folded texture of a brain.
In the case of Mars, the folds around these craters were likely created by the interaction between the soil and melting water ice.
The craters are part of the 2,050-mile-wide (3,300 kilometers) Utopia Planitia, the largest known impact basin not only on Mars but in the entire solar system.
The true-color image was acquired by Mars Express' High Resolution Stereo Camera and shows the planet's surface with a resolution of about 62 feet per pixel (19 meters). – Tereza Pultarova
Satellites spot burping Krakatoa volcano
Tuesday, March 29, 2022: Satellites have spotted a minor eruption of the Krakatoa volcano in Indonesia, one of the world's most feared volcanoes.
A plume of smoke can be seen rising from Krakatoa's crater in this image, captured by the European Sentinel 2 satellite on Monday (March 28). The volcano is notorious for its 1883 eruption, the most devastating volcanic eruption in recorded history, which killed over 36,000 people. A collapse of the volcano's caldera in 2018 caused a tsunami that killed more than 400.
The volcano woke up again in February and has been monitored ever since. Krakatoa is known to produce large amounts of ash that could damage aircraft engines. – Tereza Pultarova
Satellites watch as Antarctic ice shelf collapses amid heatwave
Monday, March 28, 2022: European Earth observation satellites observed nearly in real time as a massive ice shelf in East Antarctica collapsed due to unusually high temperatures in mid-March.
The Conger ice shelf, 450 square miles (1,165 square kilometers) in size, was photographed by the Sentinel-2 satellite of the European Earth Observation program Copernicus on Jan 30 2022 (the image on the left), when it was still intact. When the satellite flew over the ice shelf again on March 21, all it saw was a sea full of floating ice rubble.
In the week prior to the collapse, record-breaking temperatures were measured in Antarctica.
East Antarctica’s climate was previously thought to be stable and not heavily affected by climate change, Copernicus said in a statement. An ice shelf collapse had never been registered in that area, the agency added.
Scientists say that the Conger ice shelf collapse is the second most significant ice shelf collapse since that of the Larsen B ice shelf in 2002.
Ice shelves are extensions of ice sheets floating over the ocean that slow down the flow of inland ice into the ocean, which is the main process responsible for sea level rise, Copernicus explained. – Tereza Pultarova
Spacewalkers do maintenance work on the space station
Friday, March 25, 2022: European astronaut Matthias Maurer performed his first ever spacewalk on Thursday (March 24), working with his American colleague Raja Chari to fix equipment around the orbital outpost.
During the spacewalk, which lasted nearly seven hours, the two astronauts installed some radiator hoses on a system that regulates the temperature inside the space station, replaced an external camera on the station's truss and installed a power and data cable on the Bartolomeo science platform outside the European Columbus module. – Tereza Pultarova
Mariupol theatre destruction seen from space
Thursday, March 24, 2022: Satellites of U.S. Earth observation company Planet captured this image of a theatre in the Ukrainian city of Mariupol after it had been destroyed by a Russian missile.
Hundreds of residents had been sheltering in the theatre, which is believed to have been deliberately targeted by Russian forces. On the left hand side of the image, the sign дети, children, in Russian, is clearly visible, an attempt by the Ukrainians to signal to the Russians not to target the place.
The theatre's underground air raid shelter, however, is believed to have survived the attack. – Tereza Pultarova
Floating robots meet on space station
Wednesday, March 23, 2022: Two floating robots have met for the first time aboard the International Space Station this week, although both have lived on the orbital outpost for more than two years now.
The Crew Interactive MObile companioN (CIMON), developed by the German Aerospace Center in cooperation with Airbus and IBM is an artificially intelligent assistant designed to help astronauts go about their everyday tasks.
The AstroBee, developed by a team at NASA's Ames Research Center, was designed to autonomously perform various tasks, such as monitoring the environment aboard the station.
This picture was taken by NASA astronaut Kayla Barron during the first meeting between the two robots. – Tereza Pultarova
Record-breaking heatwave hits Antarctica
Tuesday, March 22, 2022: The European Sentinel-3 satellite captured this image of Antarctica on March 18 as temperatures on the icy continent reached record highs for this time of the year.
Temperatures in parts of Antarctica were 72 degrees Fahrenheit (40 degrees Celsius) above long-term averages last week, reaching 10 degrees Fahrenheit (-12.2 degrees Celsius).
The Arctic, the icy cap around the North Pole, has also been experiencing exceptionally high temperatures. Scientists are unsure whether the two unusual heat waves can be related. – Tereza Pultarova
High-resolution satellite captures NASA's moon rocket on the pad
Monday, March 21, 2022: NASA's giant moon rocket, the Space Launch System (SLS), sits on a launch pad at Kennedy Space Center in Florida in a high-resolution image captured by a new European Earth observation satellite.
The image was captured by the Pléiades Neo satellite operated by aerospace company Airbus. Pléiades Neo provides images with 11-inch (30 centimeters) resolution, one of the highest commercially available.
Airbus didn't look for SLS by chance. The company developed the service module of the Orion crew capsule that sits atop the rocket in this image, ready for the upcoming wet dress rehearsal test that will pave the way for the uncrewed launch of the Artemis I mission later this year.
The rocket was rolled out from the iconic Apollo-era Vehicle Assembly Building last week and will be moved back after the wet dress rehearsal for final adjustments before the launch, which is currently planned for May.
The Artemis I. mission will test technologies for upcoming missions with astronauts that will eventually return humans to the surface of the moon. – Tereza Pultarova
