A barred spiral galaxy
Jan. 21, 2021: NGC 613, a barred spiral galaxy 67 million light-years away in the southern constellation of Sculptor, shows its stunning stellar markings in this image taken by the Hubble Space Telescope. The galaxy, which was first discovered in 1798, is most recognizable by its long "arms," that spiral around its nucleus clearly. -- Chelsea Gohd
'Do not touch' on the space station
Jan. 20, 2020: A sign reading "do not touch" labels this Matiss experiment on board the International Space Station. The experiment tests the antibacterial capabilities of hydrophobic (water-repelling) surfaces on the space station. With experiments like this, researchers can learn more about how microscopic organisms like bacteria live in space and how the crew can keep the station clean of illness-causing microorganisms. -- Chelsea Gohd
The Sahara from space
Jan. 19, 2021: This stunning, sandy, sienna-hued landscape is the Tanezrouft Basin (a desolate region of the Sahara Desert) as seen by the Copernicus Sentinel-2 from space. The extremely arid plain is home to scorching temperatures, little water and vegetation and has even been nicknamed the "Land of Terror." This image was captured as part of Copernicus Sentinel-2, a two-satellite mission that is part of the European Space Agency's Copernicus program. -- Chelsea Gohd
Space Launch System lights up
Jan. 18, 2021: NASA's first Space Launch System megarocket ignites its four main engines for a critical hot-fire test on Jan. 16 at the agency's Stennis Space Center near Bay St. Louis, Mississippi, apparently scaring some nearby birds in this stunning photo from NASA photographer Robert Markowitz.
During the test, the final trial of a series of tests called the Green Run, the SLS rocket fired its engines for just over 1 minute, less than the 8 minutes NASA had hoped for to replicate a full launch into orbit. But despite its shorter-than-planned duration, the test offered a dazzling sight to onlookers (and birds) at the test site. NASA engineers are analyzing the results of the test. -- Tariq Malik
Spotting a supernova
Jan. 15, 2021: The Hubble Space Telescope spotted a growing, gaseous supernova remnant, known as 1E 0102.2-7219, from a supernova explosion that occurred 1,700 years ago during the fall of the Roman Empire. The star that exploded in the event was from the Small Magellanic Cloud, a satellite galaxy to our own Milky Way Galaxy located about 200,000 light-years away.
At the time of the supernova event, people living in Earth's southern hemisphere would have been able to see the light coming from this blast, though there are no known records of the event from humans on Earth. -- Chelsea Gohd
Microbes and asteroids
Jan. 14, 2021: The "BioAsteroid" payload from the University of Edinburgh runs aboard the European Space Agency's Kubik facility in the Columbus module on the International Space Station. The miniature laboratory contains asteroid-like rocky fragments and microbes (a mixture of bacteria and fungi). Scientists hope to use this experiment to understand better how these microscopic little organisms interact with the asteroid-like material, which could later inform asteroid mining efforts. -- Chelsea Gohd
Watching the weather from space
Jan. 13, 2021: In this view from space captured by the Copernicus Sentinel-3 satellite, you can see a heavy blanket of snowfall over much of Spain. The image, snapped at 5:40 a.m. EST (1040 GMT) on Jan. 12, shows most of the country covered in snow following storm Filomena, which brought the heaviest snowfall that Spain has seen for 50 years.
Copernicus Sentinel-3 is a two-satellite mission that, with a variety of instruments, observes and monitors Earth's surface from above. -- Chelsea Gohd
Jan. 12, 2021: Astronauts practice for spaceflight here on Earth in a number of unique ways, including underwater. In this image, astronauts practiced a maneuver designed for the International Space Station underwater at the Neutral Buoyancy Lab, which is operated by NASA. At this testing facility, astronauts get completely suited up as if they were about to go out on a spacewalk and perform spacewalk tasks underwater on a mock space station.
Later this month, NASA astronauts Victor Glover and Mike Hopkins will put their training to the test as they will embark on a spacewalk during which they will install a small, fridge-sized device on the outside of the space station's Columbus module. -- Chelsea Gohd
Jan. 11, 2021: This strange, green glow is actually a new type of star that, until recently, hadn't been observed in X-ray light. Scientists think that this star formed when two white dwarf stars (the leftover stellar cores of stars like our sun) merged into one another, forming a new object that emits X-ray light instead of being destroyed in the collision. -- Chelsea Gohd
Jan. 8, 2021: The galaxy NGC 6946, nicknamed "the Fireworks Galaxy," can be seen in this stunning image from the NASA/ESA Hubble Space Telescope. The galaxy got its explosive nickname because, while our Milky Way galaxy has an average of just 1-2 supernovas per century, NGC 6946 has had 10 in the last century.
"The Fireworks Galaxy," the structure of which is somewhere between a full spiral and a barred spiral, can be found 25.2 million light-years from Earth on the border of the constellations Cepheus and Cygnus. -- Chelsea Gohd
Reflecting on the sun
Jan. 7, 2021: What might look like an artistic mosaic from afar is actually 366 images of the sun throughout the year 2020, taken by the European Space Agency's Proba-2 satellite. Proba-2 continuously monitors the Sun and, in this collection of photos, there is one image selected for each day (the "extra" day is from February 29, 2020 which was leap day). These images, which were taken by Proba-2's SWAP camera (which captures ultraviolet wavelengths to show the Sun's extreme atmosphere), have a number of "easter eggs" including partial solar eclipses visible on June 21 and December 14. -- Chelsea Gohd
Jan. 6, 2021: This up-close photo shows a radish grown to perfection. These radishes serve as a control crop for the radishes currently being grown as part of the Plant Habitat-02 (PH-02) experiment in the microgravity environment onboard the International Space Station. This crop of radishes was grown in the Advanced Plant Habitat inside the Space Station Processing Facility at NASA's Kennedy Space Center in Florida. -- Chelsea Gohd
A new year in space
Jan. 5, 2021: The astronauts currently living and working on the International Space Station posed for a festive photo to ring in the new year as 2020 became 2021. NASA astronaut Victor Glover shared the photo on Twitter with the caption "God bless you and this new year! I pray for renewed strength, compassion, and truth and that we can all be surrounded by family and friends..." Glover flew to the space station as part of SpaceX's Crew-1 mission, the company's first fully operational crewed mission to space. -- Chelsea Gohd
Dec. 28, 2020: This crop of radishes on the International Space Station is a welcome sight of green for astronauts living aboard the orbiting lab. NASA astronaut Kate Rubins grew the space veggies in the Plant Habitat-02 as part of an experiment to study how plants grow in space, and how it affects the nutrition and taste of food plants for astronauts. -- Tariq Malik
Earthrise for Christmas
Dec. 25, 2020: Three NASA astronauts had a Christmas like no one on Earth in 1968. That's because the Apollo 8 astronauts Frank Borman, Jim Lovell and Bill Anders were visiting the moon. This iconic Earthrise image was captured by the astronauts on Christmas Eve, showing all of humanity from the vantage point of the lunar orbit. -- Tariq Malik
A Starship flies
Dec. 24, 2020: SpaceX's Starship SN8 prototype lifts off from a pad near Boca Chica, Texas in this view from stunning Dec. 8 test launch of the 12-story rocket. The finned spacecraft flew to an altitude of nearly 8 miles, flipped over and glided back to Earth making an epic explosion during its landing attempt. Despite the explosion, SpaceX hailed the test launch as a successful trial of the Starship concept. A new vehicle, called SN9, is already on the launch pad awaiting its own test flight
On Dec. 23, SpaceX released a new video recap showcasing the Starship SN8 flight. -- Tariq Malik
A 'Molten Ring' in the cosmos
Dec. 23, 2020: This image, taken by the NASA/ESA Hubble Space Telescope, shows the Einstein ring GAL-CLUS-022058s. Einstein rings are created when the light from distant objects like galaxies pass by an extremely massive object. Because of the process known as gravitational lensing, this light is bent and distorted into this amazing, bright curve or "ring." Scientists can use these rings to study galaxies that might otherwise be too faint or far away to see. -- Chelsea Gohd
Dec. 22, 2020: This "space bubble" was created by the Multiscale Boiling experiment otherwise known as Rubi. Installed in the Fluid Science Laboratory in the Columbus module of the International Space Station, Rubi helps researchers to understand how boiling acts in the weightless environment of space. In this image, you can see electrostatic forces pulling the bubble upwards. -- Chelsea Gohd
A far-off galaxy
Dec. 21, 2020: In this image captured by the Hubble Space Telescope, you can see the galaxy NGC 1947, a lenticular galaxy or disc galaxy that's lost most of its interstellar matter. Lenticular galaxies, because of their lost matter, don't have a lot of star formation happening within them. This galaxy was discovered almost 200 years ago and rests in the constellation Dorado (The Dolphinfish) 40 million light-years from Earth. -- Chelsea Gohd
Snow from space
Dec. 17, 2020: After a bout of heavy snowfall, the snow-covered Alps can be seen from space in this image snapped by the Copernicus Sentinel-3 mission. Copernicus Sentinel-3 is made up of two satellites and collects data for the European Copernicus environmental monitoring program. With this image, it captured the aftermath of two snowstorms in the Austrian and Italian Alps during which up to a collective 9.8 feet (3 meters) of snow fell. -- Chelsea Gohd
A dark storm reverses on Neptune
Dec. 16, 2020: Astronomers spotted a dark swirling vortex on Neptune suddenly reverse direction using the Hubble Space Telescope. The storm, discovered in 2018 using Hubble, began in Neptune's northern hemisphere and was traveling towards the equator. Scientists expected that as this happened the storm would become less and less visible. However, in August 2020, scientists using Hubble noticed the storm changing direction going back northwards. -- Chelsea Gohd.
Saturn and Jupiter in the evening sky
Dec. 15, 2020: In this photograph taken from Shenandoah National Park in Luray, Virginia, you can see the planets Saturn and Jupiter nestled close together in the sky at sunset. Saturn and Jupiter are nearing a "great conjunction" on Dec. 21. During the exciting, astronomical event, the two planets will appear to be so close together in the sky, they will be just a tenth of a degree apart from one another. -- Chelsea Gohd
Working in space
Dec. 14, 2020: Expedition 64 crew members, including NASA astronauts Kate Rubins and Soichi Noguchi, worked together to explore medical therapies for both cancer and heart conditions. Members of the crew also swapped out U.S. spacesuits inside of SpaceX's Cargo Dragon resupply ship as one suit was returned to the station and one will go back to Earth for maintenance. -- Chelsea Gohd
A sparkling, cosmic masterpiece
Dec. 11, 2020: This image seems almost too cartoonish and sparkly to be real, but it is yet another stunning, unique view of the cosmos snapped by the Hubble Space Telescope. To capture this image, Hubble used a single infrared filter with its Wide Field Camera 3 (WFC3). The image depicts stars near the center of the active galaxy Caldwell 96 (or NGC 2516). There are also a number of background galaxies that are visible (though fuzzy) in the image. -- Chelsea Gohd
SN8's test flight goes explosively well
Dec. 10, 2020: SN8, SpaceX's latest Starship prototype, launched on its first high-altitude test flight last night (Dec. 9, 2020) taking off at 5:45 p.m. EST (2245 GMT) from SpaceX's facility near Boca Chica, Texas. After a spectacular take-off, SN8 guided itself back to the ground where it landed near the launch stand. While the vehicle performed well throughout the test it came in a little too fast for the landing and touched down explosively. Still, the merits of the test flight were many and the SpaceX team, and most notably its founder Elon Musk, was thrilled with how it went. -- Chelsea Gohd
A 3D printed test ring
Dec. 9, 2020: This shiny little piece of metal is a test segment from what is known as a launch interface ring, a ring that secures a satellite in place for its tough journey from Earth to space. The ring from which this segment was plucked was 3D printed with an aluminum-magnesium-scandium alloy as part of a European Space Agency Project designed to improve the technique known as LIRAM (Launch Interface Rings by Additive Manufacturing). -- Chelsea Gohd
A cosmic wonderland
Dec. 8, 2020: In this image taken by the Hubble Space Telescope, you can see the sparkling, sprawling wonder of space. Featured in this image is the galaxy SDSS J225506.80+005839.9.

Friday, Dec. 4, 2020: This amazing close-up shows a view of a Soyuz-2 rocket's first stage engines as it launched three new Gonets-M communications satellites and a military nanosatellite into orbit for Russia's Ministry of Defense. The launch occurred Wednesday (Dec. 2) at 10:14 p.m. EST (0114 GMT or 3:14 a.m. Moscow time Thursday, Dec. 3) at the Plesetsk Cosmodrome in northern Russia. You can watch an amazing video of the launch here. -- Tariq Malik
Hubble spots a strange galaxy
Nov. 30, 2020: The Hubble Space Telescope spotted the galaxy NGC 2770 in this close-up view. The galaxy has been home to four different observed supernovae over the years, making it unusual and especially interesting to scientists studying the far-out cosmos. One of the supernovae spotted in the galaxy, SN 2015bh, was first thought to possibly not be a supernova but rather a strange outburst from an old, massive star. However, it was later correctly classified as a supernova created when a star 8-50 times as massive as our sun died.
Happy 'Black Hole' Friday!
Nov. 27, 2020: While people flock to stores online and in person for annual Black Friday sales, NASA wants you to think a bit more cosmic with Black Hole Friday.
This image is an artist's depiction of a black hole, an object with such a strong gravitational pull that not even light can escape. What falls in can't get out. Check out our black hole primer here and wow you're friends for cosmic facts while searching for Black Friday deals! -- Tariq Malik

A space amethyst
Tuesday, November 18, 2020: The planetary nebula IC 4593 shines like a brilliant purple amethyst in space in this view from NASA's Chandra X-ray Observatory.
IC 4593 is about 7,800 light-years from Earth and is the farthest planetary nebula that can be seen with Chandra. This view includes some visible-light observations from the Hubble Space Telescope combined with Chandra's X-ray view, according to a NASA image description. The Hubble views are the pink and green hues, while Chandra's X-ray detections show as purple.
Planetary nebulas aren't related to planets at all. They are super-hot bubbles of gas from dying stars that form when the star sheds its outer layers as it contracts. — Tariq Malik
A Dragon flies over Earth
Tuesday, November 17, 2020: Backdropped by a blanket of clouds, SpaceX's Crew Dragon spacecraft approaches the International Space Station with four Expedition 64 crew members in this view captured from the orbiting laboratory.

ESO's New Technology Telescope is back in action
Wednesday, November 11, 2020: The three brightest planets in the night sky flaunt their colorful features in this montage of images captured by the European Southern Observatory's New Technology Telescope, located at the La Silla Observatory in Chile. After taking a hiatus during the coronavirus pandemic, the telescope captured these images to test out its instruments before resuming science operations.
The relative sizes of the three planets in this montage is proportional to their apparent size in the night sky. Mars appears a bit bigger than usual because the photo was taken around the same time the Red Planet was at opposition, the point in its orbit where it is directly opposite the sun in Earth's sky, in mid-October. The Red Planet was also at its closest point to Earth on Oct. 6. — Hanneke Weitering
Crew Dragon on the launch pad

Orange airglow over La Silla
Friday, June 5, 2020: The starry night sky is ablaze with orange airglow in this stunning, fulldome view of the La Silla Observatory in Chile, captured by astrophotographer Guillaume Doyen. This soft, orange luminescence is the result of solar particles interacting with Earth's atmosphere, causing the air to emit visible light.
"Airglow on this night was especially intense, with the strong emissions of orange and red light rippling across the sky visible with the naked eye, even after the sun had set," officials with the European Southern Observatory (ESO), which operates telescopes at La Silla, said in an image description. ESO's TRAPPIST-South telescope, which famously discovered the TRAPPIST-1 system of Earth-size exoplanets, is visible in the foreground of the image. — Hanneke Weitering

Hubble eyes a star cluster with a dustless heart
Friday, May 29, 2020: The massive star cluster Westerlund 2, seen here in a new image from the Hubble Space Telescope, is filled with young stars surrounded by dense clouds of interstellar dust that's in the process of forming baby planets. But the stars in the center of the cluster don't have the same planet-building supplies as their neighbors near the cluster's outskirts, Hubble observations have revealed. The absence of dust in the center of Westerlund 2 is caused by "blistering ultraviolet radiation and hurricane-like stellar winds" coming from the biggest and brightest stars of the cluster, which congregate in the cluster's core, eroding and blasting away all the dust, Hubble officials said in a statement. — Hanneke Weitering
Crew Dragon at sunset
Wednesday, May 27, 2020: The sun sets behind a SpaceX Falcon 9 rocket on Launch Complex 39A at the Kennedy Space Center in Florida for the last time before the rocket's planned launch of two NASA astronauts to the International Space Station.

Tuesday, May 19, 2020: The dusty arc of the Milky Way galaxy stretches across the night sky in this circular fisheye view. European Southern Observatory (ESO) photo ambassador Mahdi Zamani captured this image from Cerro Armazones, a mountain in northern Chile. "Thanks to the exceptionally clear and dark skies, the thousands of stars and dusty clouds that make up the Milky Way Galaxy are visible," ESO said in an image description. The elusive zodiacal light is shown in the top right while a faint orange airglow lights up the entire night sky. — Hanneke Weitering
A galactic duet
Monday, May 18, 2020: Two spiral galaxies collectively known as Arp 271 look like they're getting ready to collide. The two interacting galaxies, NGC 5426 and NGC 5427, have formed a bridge of material where new stars are beginning to form. If the galaxies do end up crashing into each other, the collision will trigger a wave of new star formation over the next few million years, according to the European Southern Observatory (ESO). This same type of interaction may happen to our own Milky Way galaxy when it collides with the Andromeda galaxy in the next five billion years or so, ESO said. — Hanneke Weitering
Crew Dragon splashes down after drop test
Friday, May 15, 2020: A mockup of SpaceX's Crew Dragon capsule with two crash test dummies inside splashes into the water during a drop test at NASA's Langley Research Center in Hampton, Virginia. SpaceX conducted a series of these drop tests in March 2019 to find out how different wind and parachute dynamics affect the capsule during a splashdown, and to make sure its astronaut occupants can safely return to Earth. Less than two weeks from now, a real Crew Dragon will launch astronauts to the International Space Station for the first time. — Hanneke Weitering
A galactic bridge in Abell 2384
Thursday, May 14, 2020: A few hundred millions years ago, two distant galaxy clusters collectively known as Abell 2384 collided, passing through each other and creating a "bridge" of hot gas between the clusters that spans more than 3 million light-years. A new composite image of Abell 2384 has revealed that a supermassive black hole lurking at the center of one of these galaxy clusters is shaping this galactic bridge by blasting it with a powerful jet of energetic particles.
The new image combines X-ray data from Europe's XMM-Newton telescope and NASA's Chandra X-ray Observatory (shown in blue), along with radio observations from the Giant Metrewave Radio Telescope in India (shown in red) and optical data from the Digitized Sky Survey (shown in yellow). — Hanneke Weitering

The NG-13 cargo ship, which delivered 7,500 lbs. (3,400 kilograms) of supplies for the station's three-person Expedition 62 crew in February, will spend the next few weeks flying solo in orbit, deploying tiny satellites and conducting a fire experiment. It will fall back to Earth on May 29 and safely burn up in our planet's atmosphere above the Pacific Ocean. — Hanneke Weitering
NASA satellite spots a winter wonderland
Tuesday, May 12, 2020: This wintery landscape may look like the scene of an ancient, frosty river on Mars, but this image was taken by a satellite orbiting our own planet. The winding waterway flowing through this frame is the Dnieper River in Ukraine. It is the fourth-longest river in Europe, with a total length of about 1,400 miles (2,200 kilometers). NASA's Terra satellite captured this view of a portion of the Dnieper River near the Ukrainian city of Oster using its Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) instrument, which images Earth to map and monitor the changing surface of our planet. — Hanneke Weitering

"This WW2 medical armband accompanied me to @space_station and will soon reside @NatlArmyMuseum." Morgan returned from the space station in April after spending 272 days on board the orbiting lab. — Hanneke Weitering
Hubble eyes a two-armed galaxy
Friday, May 8, 2020: This new image from the Hubble Space Telescope features the barred spiral galaxy NGC 3583. Located some 98 million light-years away from Earth in the constellation Ursa Major, NGC 3583 is about three-quarters the size of our Milky Way galaxy. But while the Milky Way has four distinct spiral arms that wrap around its galactic core, NGC 3583 has two long arms that twist out into the universe. Astronomers have observed two supernova explosions in this galaxy, one in 1975 and then again in 2015. — Hanneke Weitering
Full Flower Supermoon
Thursday, May 7, 2020: The nearly-full moon of May, known as the Flower Moon, gleams against the twilight sky in this photo taken by Kevin M. Gill of Los Angeles, California, on Wednesday night. The moon reached full phase this morning at 6:45 a.m. EDT (1045 GMT). According to NASA, this was the fourth and final "supermoon" of 2020, although some astronomers disagree about whether it qualified as a "supermoon." — Hanneke Weitering
A black hole hides among the stars
Wednesday, May 6, 2020: Lurking stealthily in the center of this wide-field image of the Telescopium constellation is the closest black hole to Earth, a record-breaking discovery that astronomers announced today. The newfound black hole is located about 1,000 light-years from Earth in what astronomers originally believed to be a binary, or double-star system. But thorough observations of the star system, called HR 6819, revealed an invisible third object influencing the stars' orbits. Although the black hole itself is invisible, the stars in the HR 6819 system are bright enough to see without a telescope in a dark, clear sky from the Southern Hemisphere. This image of HR 6819 was captured as part of the Digitized Sky Survey 2. — Hanneke Weitering

"Stretched" spiral galaxy bursts with baby stars
Friday, May 1, 2020: A new image from the Hubble Space Telescope features the sparkling spiral galaxy NGC 4100, which is teeming with baby stars. The galaxy's spiral arms are speckled with pockets of bright blue starlight radiating from hot newborn stars. NGC 4100 is located about 67 million light-years from Earth in the constellation Ursa Major, and it belongs to a group of galaxies called the Ursa Major Cluster. It's about three-quarters the size of the Milky Way, which is also a spiral galaxy, and it "looks almost stretched across the sky" in this new view, Hubble scientists said in a statement. The space telescope captured this image using its Advanced Camera for Surveys, and it was released today (May 1). — Hanneke Weitering
"Spiders" spotted on Mars
Thursday, April 30, 2020: Strange, spider-like features creep on the surface of Mars in this image taken by the High-Resolution Imaging Science Experiment (HiRISE) camera on board NASA's Mars Reconnaissance Orbiter. These spidery landforms are what scientists call "araneiform" terrain, which literally translates to "spider-like." The features arise because the Red Planet's climate is so cold that during the Martian winter, carbon dioxide freezes from the atmosphere and accumulates as ice on the surface. When that ice begins to thaw in the spring, that carbon dioxide sublimates back into the atmosphere, or turns from a solid to a gas, leaving behind deep troughs in the terrain as gas is trapped below the surface. — Hanneke Weitering
Dwarf galaxy "steals the show" in Hubble image
Wednesday, April 29, 2020: In a deep-space image featuring countless distant galaxies of all shapes and sizes, a tiny dwarf galaxy takes center stage. The small elliptical galaxy in the foreground of this new Hubble Space Telescope image is known as PGC 29388. It contains between 100 million to a few billion stars, which pales in comparison to our Milky Way galaxy, which has 250 to 400 billion stars. "As beautiful as the surrounding space may be, the sparkling galaxy in the foreground of this image from the NASA/ESA Hubble Space Telescope undeniably steals the show," Hubble scientists said in a statement. The image was released on April 20, a few days before the telescope celebrated its 30th anniversary. — Hanneke Weitering

Hubble captures a "cosmic reef"
Friday, April 24, 2020: Happy birthday, Hubble! To celebrate the 30th anniversary of the launch of the Hubble Space Telescope, NASA released this new image of a "cosmic undersea world" that is teeming with stars and colorful clouds of interstellar dust and gas. The image features the giant red nebula NGC 2014 and its smaller blue companion NGC 2020, both located in the Large Magellanic Cloud, a small satellite galaxy of the Milky Way located 163,000 light-years from Earth. Hubble scientists have nicknamed the image the "Cosmic Reef," because the large nebula "resembles part of a coral reef floating in a vast sea of stars," Hubble officials said in a statement. — Hanneke Weitering
A Lyrid meteor and the Milky Way
Thursday, April 23, 2020: A "shooting star" crosses the Milky Way galaxy in this photo taken during the peak of the annual Lyrid meteor shower. Photographer Tina Pappas Lee captured this view from Fripp Island, South Carolina, on Wednesday (April 22) at approximately 4:45 a.m. local time.

Apollo 16's "Earthrise"
Wednesday, April 22, 2020: Happy Earth Day from space! This stunning view of Earth rising above the lunar horizon was captured by NASA's Apollo 16 crew shortly before they landed on the moon 48 years ago. The astronauts snapped this picture, which appears to have been inspired by Apollo 13's famous "Earthrise" photo, on April 20, 1972, the same day the lunar module Orion touched down on the surface with NASA astronauts John Young, Apollo 16 commander, and lunar module pilot Charlie Duke. Command module pilot Ken Mattingly stayed in orbit during their 71-hour stay on on the surface. — Hanneke Weitering
Starlink satellites spotted from space
Tuesday, April 21, 2020: A chain of SpaceX's Starlink internet satellites orbits over Earth's lime-green auroras in this photo captured by an astronaut at the International Space Station. The tiny satellite trails were captured on Monday (April 13) at 5:25 p.m. EDT (2125 GMT), as the station was passing over the southern Indian Ocean at an altitude of about 231 nautical miles (428 kilometers), NASA said in an image description. The satellites pictured here appear to belong to the fifth batch of approximately 60 satellites that SpaceX has launched for its new Starlink constellation, according to Jonathan McDowell, an astronomer at the Harvard-Smithsonian Center for Astrophysics who avidly tracks objects in Earth's orbit. The company plans to launch its seventh batch of satellites on Wednesday (April 22). — Hanneke Weitering

Hubble eyes a multiring galaxy
Thursday, April 16, 2020: The Hubble Space Telescope has captured this new view of a peculiar spiral galaxy with rings within its winding galactic arms. Known as NGC 2273, this galaxy is officially designated as a barred spiral, meaning that it has a central bar of stars and pinwheeling arms. But this galaxy also has several ring structures within its spiral arms. NGC 2273 hosts one inner ring along with two outer "pseudorings." Astronomers believe these rings were created by spiral arms appearing to wind up tightly into a closed loop. — Hanneke Weitering
Soyuz approaches the space station
Wednesday, April 15, 2020: Earth's fluffy clouds and blue horizon provide a gorgeous backdrop for the Soyuz MS-16 crew spacecraft, seen here approaching the International Space Station with three Expedition 63 crewmembers on board. The Soyuz arrived at the orbiting lab on Thursday (April 9) with NASA astronaut Chris Cassidy and Russian cosmonauts Anatoly Ivanishin and Ivan Vagner.

"Pink Moon" seen from space
Wednesday, April 8, 2020: The nearly-full Pink Moon rises over a cloud-covered Earth in this photo taken by an astronaut at the International Space Station. This photo was taken on Monday (April 6), one day before the supermoon, or a full moon that coincides with the moon's perigee, the closest point to Earth in its orbit. Because the full moon of April is traditionally called the Pink Moon, last night's supermoon has been referred to as the "Super Pink Moon." — Hanneke Weitering
Juno spots hazy clouds on Jupiter
Tuesday, April 7, 2020: Hazy clouds streak across Jupiter's northern hemisphere in this new image from NASA's Juno spacecraft. These long, thin cloud bands consist of haze particles that drift above the planet's underlying cloud features. While the cause of these wispy clouds is still a bit of a mystery, scientists believe the hazy features could be related to Jupiter's jet streams. "Two jet streams in Jupiter's atmosphere flank either side of the region where the narrow bands of haze typically appear, and some researchers speculate those jet streams may influence the formation of the high hazes," NASA officials said in a statement. T
he Juno orbiter captured this image during its 25th close flyby of Jupiter, also known as a perijove, on Feb. 17 at 12:29 p.m. EST (1729 GMT), when the spacecraft was about 15,610 miles (25,120 kilometers) from the planet's cloud tops. — Hanneke Weitering
Two Saturnian moons

Citizen scientist Kevin Gill recently processed this 10-year-old view of Saturn and two of its moons using calibrated red, green and blue filtered images captured by the Cassini spacecraft on March 28, 2010. — Hanneke Weitering
Hubble eyes a one-arm spiral galaxy
Friday, April 3, 2020: A new Hubble Space Telescope image reveals the peculiar structure of a spiral galaxy with only one starry arm rotating about its center. While most barred spiral galaxies are characterized by a distinct bar-shaped structure of stars centered on a galactic core, this barred spiral isn't like most others. Located 21 million light-years from Earth in the constellation Canes Venatici, this strange galaxy, known as NGC 4618, was first thought to be a star cluster when the astronomer William Herschel discovered it in 1787. Astronomers now think that gravitational interactions with a neighboring galaxy may have influenced this galaxy's shape. — Hanneke Weitering
Venus meets the Pleiades
Thursday, April 2, 2020: The bright planet Venus begins its trek past the Pleiades star cluster, also known as the "Seven Sisters," in this photo taken by astrophysicist Gianluca Masi of the Virtual Telescope Project in Italy on Wednesday (April 1). Venus, which reaches its greatest brightness of the year at the end of the month, will make a close approach to the Pleiades tomorrow (April 3), when the two objects will be in conjunction — meaning they share the same celestial longitude — for the first time in 8 years. During the conjunction, Venus will be just one-quarter of a degree southeast of Alcyone, the brightest star in the cluster. Look for the pair in the western evening sky. You can also watch a live stream of the encounter from the Virtual Telescope Project here, starting at 1:30 p.m. EDT (1730 GMT). — Hanneke Weitering
Webb telescope deploys its mirrors
Wednesday, April 1, 2020: NASA's James Webb Space Telescope has successfully deployed its giant primary mirror, putting the new observatory one big step closer to being ready for launch in 2021. The entire 256-inch (6.5 meters) primary mirror assembly unfurled into the same configuration that it would be after deploying in space. This critical test took place in early March, right before NASA's centers shut down due to the coronavirus pandemic. Work on the Webb telescope was temporarily halted on March 20. It is scheduled to launch in March 2021, though even before the coronavirus pandemic, that date was expected to slip. — Hanneke Weitering
A "fluffy" spiral galaxy
Tuesday, March 31, 2020: While most spiral galaxies have clearly defined arms the twist around a galactic core, others have patchy spiral arms that are not clearly distinguishable and resemble cotton wool. Due to this wooly appearance, the galaxy NGC 4237, shown here in a new image from the Hubble Space Telescope, is classified as a "flocculent" spiral galaxy. Located 60 million light-years from Earth in the constellation of Coma Berenices, or "Berenice's Hair," NGC 4237 has been a target for astronomers, not because of its fluffy appearance, but because its bright central region may bear clues about how supermassive black holes form inside galaxies. — Hanneke Weitering
Airglow shines over Malaysia and Indonesia
Monday, March 30, 2020: City lights of Malaysia and Indonesia light up the Earth beneath a blanket of blue and orange airglow while boat lights glow in the Bay of Bengal in this nighttime view of Earth from space.

Image 1 of 2
Image 2 of 2
Friday, March 27, 2020: Comet C/2019 Y4 Atlas is slowly brightening in the night sky as it gets ready to swing around the sun in a couple months. Astrophotographer Mike Cuffe captured these two images of the green comet through his backyard telescope on Monday (March 23). In the first stacked image, the comet appears a bit blurry as it moves across a fixed background of stars. For the second image, the telescope was fixed on the comet, so the background stars appear as short trails behind a sharper image of the comet. Comet C/2019 Y4 Atlas is expected to make its closest approach to Earth on May 23, about one week before it reaches perihelion, or its closest point to the sun. It will brighten dramatically during this approach, and it may become visible to the naked eye in late April or May. — Hanneke Weitering

VLT's Laser Guide Star
Wednesday, March 25, 2020: The European Southern Observatory's Very Large Telescope (VLT) beams its laser guide star into the night sky over Chile, creating a beam of light that arcs above the Milky Way galaxy. Astronomers use giant laser beams like these to help their telescopes correct for the distortion caused by turbulence in Earth's atmosphere, which can make stars appear to twinkle. For observations at the VLT, astronomers rely on the Laser Guide Star Facility at the Paranal Observatory in Chile. Pictured in the foreground are four domes of the SPECULOOS Southern Observatory. — Hanneke Weitering

Milky Way over ELT
Thursday, March 19, 2020: In this stunning night sky photo, the full arc of the Milky Way galaxy glitters over a photographer's shadow at the construction site for the European Southern Observatory's Extremely Large Telescope (ELT), on the Chilean mountain Cerro Armazones. Scheduled to open in 2025, ELT will be "the world’s biggest eye on the sky," with a 39-meter (128-foot) primary mirror. ELT will scan the skies in optical and near-infrared wavelengths of light to search for worlds beyond our solar system, particularly for potentially Earth-like exoplanets. It will also help astronomers study how planets, stars, galaxies and black holes formed in the early universe. — Hanneke Weitering
A stellar nursery in the Tarantula Nebula
Wednesday, March 18, 2020: A new Hubble Space Telescope image features a stellar nursery on the outskirts of the Tarantula Nebula. Known as LHA 120-N 150, this bright pink space cloud is located more than 160,000 light-years away from Earth in the Large Magellanic Cloud, a dwarf galaxy that orbits the Milky Way. This colorful nebula is rich with new star formation, and it has an "exceptionally high concentration of massive stars, Hubble scientists said in a statement. By studying LHA 120-N 150, astronomers hope to learn more about the kind of environment in which massive stars form. — Hanneke Weitering
Happy St. Patrick's Day from space!
Tuesday, March 17, 2020: To honor St. Patrick's day at the International Space Station today, NASA astronaut Andrew Morgan tweeted this photo of an Irish flag floating in one of the windows of the Cupola observatory in the orbiting lab. One of the space station's solar arrays is visible through the window, while Earth provides a cloudy backdrop. Along with this photo of the flag, Morgan tweeted a photo of Ireland, also known as the Emerald Isle, that he captured from the space station. — Hanneke Weitering
U.S. Eastern Seaboard seen from space

On the right is a portion of the station's Canadarm2 robotic arm. — Hanneke Weitering
A galaxy with "hunger pangs"
Friday, March 13, 2020: A new Hubble Space Telescope image of the spiral galaxy NGC 1589 reveals the galaxy's bright central bulge, where a supermassive black hole is lurking in a group of tightly packed stars. The galaxy "was once the scene of a violent bout of cosmic hunger pangs," Hubble astronomers said in a statement.
Located 168 million light-years from Earth in the Taurus constellation, NGC 1589 was discovered by William Herschel in 1783. "As astronomers looked on, a poor, hapless star was seemingly torn apart and devoured by the ravenous supermassive black hole at the center of the galaxy," the Hubble team said. Now astronomers are using Hubble to look for any evidence of stellar debris that was ejected when the star ripped apart. — Hanneke Weitering
China's city lights seen from space
Thursday, March 12, 2020: City lights illuminate southeast China by night in this photo taken by an astronaut at the International Space Station. The large, bright cluster of lights near the center of this image represent the city of Shanghai, the most highly populated city in the country, located on the coast of the East China Sea. The small, dense cluster just to the left of Shanghai is the city of Hefei, the capital of Anhui and the largest city in that province of China. In the bottom left corner of the image is Wuhan, the capital of Hubei province and "ground zero" of the novel coronavirus outbreak. This photo was taken on March 5, as the International Space Station passed over the Asian continent at an altitude of about 259 miles (417 kilometers). — Hanneke Weitering
Milky Way sparkles over Yellowstone
Wednesday, March 11, 2020: The Milky Way shimmers over Yellowstone National Park in this starry night-sky photo by Chirag Upreti. This panorama combines 10 frames captured from the "Mound and Jupiter Terrace" at Mammoth Hot Springs, and it features an excellent view of the planet Jupiter, shining brightly to the right of the Milky Way while reflecting off the surface of the water below. Saturn is also visible in the photo, shining to the left of the Milky Way, directly above the asterism known as the Teapot.
"The Dark Horse Nebula can be seen apparently jumping over the mound and to the right of Jupiter," Upreti told Space.com. "It was an amazing experience to witness the stars and the Milky Way, knowing you are standing over terrain dictated by the raw power of a supervolcano, an incredible place to feel the bond between Earth and the night sky." — Hanneke Weitering
"Super Worm Moon" rises over Washington
Tuesday, March 10, 2020: The first supermoon of the year peers through a blanket of clouds above the U.S. Capitol in Washington in this photo captured by NASA photographer Joel Kowsky on Monday (March 9). Also known as the "Worm Moon," the full moon of March nearly coincided with the moon's perigee, or the closest point to Earth in the moon's elliptical orbit. The moon was officially full on Monday at 1:48 p.m. EDT (1748 GMT), and it reached perigee almost 13 hours later, at 2:33 a.m. EDT (0633 GMT) today. — Hanneke Weitering
SpaceX's Dragon arrives at the space station
Monday, March 9, 2020: This Dragon cargo ship marked the end of an era of sorts for private spaceship builder SpaceX when it arrived at the International Space Station today. The Dragon CRS-20 spacecraft seen here is the last SpaceX Dragon to be captured by a robotic arm and attached to the station. Future SpaceX Dragon resupply flights will use the company's new Dragon 2 version, which can dock itself at the station.
NASA astronaut Jessica Meir unveiled this photo on Twitter after using the station's robotic arm to capture the Dragon capsule. She wrote: "From now on, SpaceX will automatically dock to station. This Dragon capsule has been on station 2 times prior - sustainability is paramount to future space exploration." — Tariq Malik
A weird crater on Mars
Friday, March 6, 2020: A new image from the European Space Agency's Mars Express orbiter reveals an odd, misshapen impact crater on Mars known as Moreux crater. While most craters appear roughly circular in shape, the outline of Moreux crater is shaped more like a fried egg. The crater's dark walls appear ridged and rippled, while dark brown and black dunes are smeared across the crater floor. The tall peak in its center is a pile of material that was ejected from the Martian terrain when the initial impact happened a few million years ago. Moreux crater's contorted appearance developed over a long period of time, as erosion, wind and glacial activity shaped the planet's surface. This image was created using data collected by the High Resolution Stereo Camera on Mars Express, when the spacecraft flew over the area in October 2019. — Hanneke Weitering
An astronaut's view of NYC
Thursday, March 5, 2020: A new view of New York City captured from the International Space Station show's the city's skyline in incredible detail. NASA astronaut Jessica Meir photographed the city from the orbiting laboratory, which circles the Earth at an altitude of about 250 miles (400 kilometers). "Clear views of bustling #NYC day and night lately from @Space_Station," Meir tweeted on Wednesday (March 4). "Central Park looks inviting. Midtown's skyline reminds me of a metallic pin art impression." — Hanneke Weitering
A portrait of Saturn's moon Enceladus
Wednesday, March 4, 2020: A new global view of Saturn's icy moon Enceladus shows the tiny satellite's "tiger stripe" fissures and frosty plumes in stunning detail. This artist's illustration of Enceladus was created from a global map that scientists working on NASA's Cassini mission stitched together from images that the spacecraft collected during its first 10 years of exploring the Saturn system. — Hanneke Weitering
Merging storms spotted on Jupiter
Tuesday, March 3, 2020: Two white, oval-shaped storms in Jupiter's atmosphere have been spotted merging into one. NASA's Juno spacecraft caught these anticyclonic storms in the act using its JunoCam imager on Dec. 26, 2019, as the spacecraft was completing its 24th perijove, or close flyby of the planet. At the time, Juno was passing about 44,900 miles (72,200 kilometers) above Jupiter's cloud tops at a latitude of about 60 degrees south.
NASA has been tracking the larger of the two merging storms for years, and scientists have watched it gobble up several smaller storms in the past, NASA said in a statement. It narrowly avoided a merger with this same storm just a few months before this image was captured, when the two made a close approach as they churned through the planet's turbulent atmosphere. — Hanneke Weitering
Hubble spots a galactic "traffic jam"
Monday, March 2, 2020: A new image from the Hubble Space Telescope features the barred spiral galaxy NGC 3887, with its long, winding arms and bright galactic core. The German-English astronomer William Herschel discovered this galaxy, which is located 60 million light-years away from Earth, about 234 years ago. At the time, astronomers didn't understand how such spiral arms could even exist, because they thought a galaxy's spinning core would eventually wind them up so tightly that the spirals would disappear. It wasn't until the 1960s that astronomers came up with an explanation.
"Rather than behaving like rigid structures, spiral arms are in fact areas of greater density in a galaxy’s disc, with dynamics similar to those of a traffic jam," Hubble officials said in a statement. "The density of cars moving through a traffic jam increases at the center of the jam, where they move more slowly. Spiral arms function in a similar way; as gas and dust move through the density waves, they become compressed and linger, before moving out of them again." — Hanneke Weitering
Cubesat embarks on a fiery mission
Friday, February 28, 2020: The European Space Agency's Qarman cubesat deploys from the International Space Station on a mission to burn up in Earth's atmosphere to study the physics of its own fiery reentry. Officially titled the "QubeSat for Aerothermodynamic Research and Measurements on Ablation," Qarman was ejected from the space station's Nanoracks cubesat dispenser on Feb. 19.
"From there we think it will take about six months to reenter the atmosphere – to find out how accurately we can forecast Qarman's orbital decay is part of the reason we're flying the mission, relevant to the study of space debris," Olivier Chazot, head of the Aeronautic/Aerospace Department of the Von Karman Institute in Belgium, said in a statement. — Hanneke Weitering
Technicolor night sky
Thursday, February 27, 2020: The night sky above the Paranal Observatory in Chile is ablaze with vibrant airglow in this gorgeous view by astrophotographer Yuri Beletsky. This colorful phenomenon happens because atoms and molecules in Earth's atmosphere interact and emit radiation. For this reason, the sky is never completely dark. Airglow is only visible in places that are far enough from human-made light pollution, like the Paranal Observatory. This image was captured from the European Southern Observatory's Visible and Infrared Survey Telescope for Astronomy (VISTA), and in the distance you can barely see the Very Large Telescope (VLT), which sits on top of Cerro Paranal. — Hanneke Weitering
Tropical cyclones in the land Down Under
Wednesday, February 26, 2020: Tropical cyclones Ferdinand and Esther swirl over Australia in this satellite image from the NASA-NOAA Suomi NPP weather satellite. This image combines data that Suomi NPP collected as it passed over Australia twice on Monday (Feb. 24). The diagonal line marks the edge of the swath between the two satellite passes, which occurred about 90 minutes apart. Esther made landfall near Queensland on Monday and has since been downgraded to a tropical depression. Ferdinand, seen here off the northwest coast of Australia, formed over the weekend and is now a Category 2 storm, but it is not expected to make landfall. — Hanneke Weitering
Orion spacecraft prepped for Artemis 1
Tuesday, February 25, 2020: NASA's Orion spacecraft is lifted into a thermal cage ahead of its move to to the vacuum testing chamber at NASA's Plum Brook testing station in Sandusky, Ohio. The spacecraft will fly on the Artemis 1 mission, an uncrewed test flight that will launch on NASA's new Space Launch System megarocket sometime in 2021. After that mission, NASA plans to use the Orion spacecraft to fly astronauts to the moon. — Hanneke Weitering
In Memoriam: Katherine Johnson
Monday, February 22, 2020: NASA mourned the loss of one of its science icons with the death of famed mathematician and "Hidden Figure" Katherine Johnson today at age 101. Johnson joined the National Advisory Committee for Aeronautics in 1953 as a so-called human computer at the agency's Langley, Virginia, office. There, she served in the West Area Computing section, an all-black unit in the segregated center, and stayed on in 1958 when NACA became NASA.
Johnson's calculations as a human computer mapped the trajectory of astronaut Alan Shepard's historic 1961 spaceflight, when he became the first American in space, as well as for John Glenn's first orbital flight later that year. You can see our full remembrance here. -- Tariq Malik
The Sombrero Galaxy
Friday, February 21, 2020: The Sombrero Galaxy may have a smooth "brim," suggesting that its past was free of any galactic collisions, but new data from the Hubble Space Telescope has shown that this seemingly unscathed galaxy is hiding a violent past. According to NASA, the galaxy's faint outer halo provides some forensic clues that suggest the galaxy underwent multiple collisions with other galaxies billions of years ago.
"These latest observations of the Sombrero are turning conventional theory on its head, showing only a tiny fraction of older, metal-poor stars in the halo, plus an unexpected abundance of metal-rich stars typically found only in a galaxy's disk, and the central bulge," Hubble officials said in a statement. "Past major galaxy mergers are a possible explanation, though the stately Sombrero shows none of the messy evidence of a recent merger of massive galaxies." — Hanneke Weitering
Mars plays "peekaboo" with the moon
Thursday, February 20, 2020: Mars ducks behind the crescent moon's lower limb in this photo from the lunar occultation on Tuesday (Feb. 18). Astrophotographer B.G. Boyd captured this view of the crescent moon as it began to slide in front of the Red Planet in the early morning sky over Tucson, Arizona, shortly before the occultation began at 4:38 a.m. local time. About an hour later, Mars reappeared from the moon's dark limb. In this photo, the planet appears as a small orange speck that just barely touches bottom edge of the crescent moon. You can see more photos and a video of the occultation here. — Hanneke Weitering
Robot arm "waves" at the moon
Wednesday, February 19, 2020: The last quarter moon looms behind the International Space Station's Canadarm2 robotic arm in this photo by NASA astronaut Jessica Meir. She and her Expedition 62 crewmate Andrew Morgan used Canadarm2 to grapple an arriving Cygnus cargo spacecraft on Tuesday (Feb. 18). "The mighty @csa_asc #Canadarm2 ready to grapple, as @AstroDrewMorgan & I practiced our maneuvers to capture #Cygnus that is headed our way, loaded with nearly 7,500 pounds of science, cargo, and @Space_Station supplies," Meir tweeted on Saturday (Feb. 15). "Even the Moon made an appearance, awaiting #ARTEMIS eagerly," she added, referring to NASA's Artemis program, which aims to land astronauts on the moon in 2024. — Hanneke Weitering
A spiral galaxy with "open arms"
Tuesday, February 18, 2020: The spiral galaxy NGC 2008 flaunts its shimmering galactic tentacles in this new image from the Hubble Space Telescope. Originally discovered in 1834 by the astronomer John Herschel, the galaxy resides about 425 million light-years away from Earth in the southern constellation of Pictor, the painter. NGC 2008 is classified as a type Sc galaxy, which means that it is a spiral with "a relatively small central bulge and more open spiral arms," NASA said in a statement. "Spiral galaxies with larger central bulges tend to have more tightly wrapped arms, and are classified as Sa galaxies, while those in between are classified as type Sb." — Hanneke Weitering
A cosmic valentine
Friday, February 14, 2020: Happy Valentine's Day from space! The Heart Nebula, also known as IC 1805, shimmers in deep space in this photo by astrophotographer Miguel Claro. Located 7,500 light-years from Earth in the Perseus Arm of the Milky Way galaxy, the Heart Nebula resides in the constellation Cassiopeia. At the cusp of the heart is a bright, fish-shaped knot called the Fishhead Nebula. For more romantic images from across the universe, check out our cosmic Valentine's Day gallery. — Hanneke Weitering
Noctilucent clouds seen from space
Thursday, February 13, 2020: An astronaut at the International Space Station captured this image of noctilucent or "night-shining" clouds in Earth's upper atmosphere. These clouds, which are made of tiny ice crystals, are only visible during astronomical twilight, when the sun just below the horizon, but the clouds are still illuminated by sunlight. Below the blue cloud layer, the lower part of the atmosphere glows with the signature reddish color of sunset. — Hanneke Weitering
The Eskimo Nebula
Wednesday, February 12, 2020: The planetary nebula NGC 2392, also known as the "Eskimo Nebula," is the colorful remnant of a star that died about 4,200 light-years from Earth, leaving behind a brilliant orb of intricate layers and patterns. This star didn't die in a supernova explosion, but rather burned up all of its fuel, causing it to cool, expand and shed its outer layers. This image combines data collected via NASA's Chandra X-ray Observatory and the Hubble Space Telescope in 2013, and citizen scientist Kevin Gill recently reprocessed the image to bring out the nebula's detailed structure. — Hanneke Weitering
Antares rocket under the Snow Moon
Tuesday, February 11, 2020: An Antares rocket topped with Northrop Grumman's Cygnus NG-13 cargo spacecraft stands ready for launch under the almost-super Full Snow Moon at NASA's Wallops Flight Facility in Virginia. The cargo resupply mission was scheduled to launch to the International Space Station on Sunday (Feb. 9), but NASA aborted the launch at the last minute due to off-nominal data from ground support equipment. It is now scheduled to launch to earlier than Thursday (Feb. 13) at 4:05 p.m. EST (2105 GMT). — Hanneke Weitering
Solar Orbiter launches to the sun
Monday, February 10, 2020: The European Space Agency's Solar Orbiter lifts off on an Atlas V rocket from Cape Canaveral Air Force Station in Florida, on a historic mission to study the sun's poles. The Atlas V rocket successfully launched Solar Orbiter from Space Launch Complex 41 last night at 11:03 p.m. EST (0403 GMT), and this timelapse photo shows its curved path into space. Over the course of the next 20 months, Solar Orbiter will perform a series of gravity-assist maneuvers, flying by Venus and Earth before venturing to the inner solar system, where it will study the sun up close, capturing unprecedented imagery of our star's poles. — Hanneke Weitering
A fresh crater in Valles Marineris
Friday, February 7, 2020: NASA's Mars Reconnaissance Orbiter has spotted a relatively fresh crater on the Red Planet using its High Resolution Imaging Science Experiment (HiRISE) camera. While lower-resolution images can help scientists identify craters on the Martian surface, high-resolution images like this one can help them determine the age of a crater. For example, radial features known as "rays," which streak outward from the center of a crater, indicate that a crater is relatively young, because these features typically erode over time. A so-called "ejecta blanket" of dark basaltic rock, shown here in blue, creates a splash-like pattern closer to the site of the impact. NASA estimates that this crater, located in Valles Marineris, was created sometime between February and July of 2005. — Hanneke Weitering
Welcome home, Expedition 61!
Thursday, February 6, 2020: The Soyuz MS-13 crew capsule carrying three astronauts home from the International Space Station touches down on the snowy steppe of Kazakhstan in this aerial shot by NASA photographer Bill Ingalls.

Wednesday, February 5, 2020: A SpaceX Falcon 9 rocket booster sticks a vertical landing on the company's drone ship "Of Course I Still Love You" in the Atlantic Ocean, following its successful launch of 60 Starlink satellites on Jan. 29. This was the third time that this reusable rocket booster has launched and landed and the 49th time that SpaceX has recovered a Falcon 9 booster. This launch brought the total number of SpaceX's Starlink satellites up to 240, and the company already has permission from the U.S. Federal Communications Commission (FCC) to launch up to 12,000 of the internet satellites, though that number could swell to 30,000. — Hanneke Weitering
Cygnus on the move
Tuesday, February 4, 2020: A Northrop Grumman Cygnus cargo spacecraft drifts away from the International Space Station after ground controllers used the station's Canadarm2 robotic arm to send it off on Friday (Jan. 31). While most departing cargo vessels head straight back down to Earth to burn up in our planet's atmosphere after completing their mission to the space station, this cargo craft, dubbed the S.S. Alan Bean, has one more mission to tackle before it meets its fiery demise. It will spend about a month in orbit to deploy a series of small satellites that will perform a variety of science experiments in space. — Hanneke Weitering
Venus and Jupiter meet in the Milky Way
Monday, February 3, 2020: The two brightest planets in the night sky, Venus and Jupiter, meet up for a conjunction in front of the Milky Way's shimmering core in this view from the La Silla Observatory in Chile. European Southern Observatory (ESO) photo ambassador Zdenek Bardon spent three nights trying to capture this image of the planetary encounter in late November, as clouds and humidity partially obstructed the view. Usually the La Silla Observatory has clear skies and low humidity due to its high elevation; it is located on a mountain in the Atacama Desert that is nearly 8,000 feet (2,400 meters) above sea level. While Bardon was perhaps unlucky for having to wait a few days for clear skies, this stunning photo was worth the wait! — Hanneke Weitering
Astronauts gather in the Cupola observatory

Green auroras meet orange airglow
Tuesday. January 28, 2020: A vibrant, lime-green aurora lights up Earth's upper atmosphere in this photo captured by an astronaut at the International Space Station. When this photo was taken on Jan. 22, the station was orbiting 261 miles (420 kilometers) above the Atlantic Ocean off the coast of North America. Beneath the northern lights is a blanket of marmalade-colored airglow, a type of luminescence caused by ultraviolet light that triggers chemical reactions high in Earth's atmosphere. Auroras, on the other hand, are created when charged particles from the sun ionize or excite particles in the atmosphere, and they only occur near our planet's north and south poles. — Hanneke Weitering
Hubble eyes a strange spiral galaxy
Monday, January 27, 2020: The barred spiral galaxy NGC 1022 flaunts its tendrils of dark, red dust in this new view from the Hubble Space Telescope. While most barred spiral galaxies have a distinct bar of stars at their centers, the bar inside NGC 1022 is a bit more difficult to make out. To spot the faint feature, look for the swirling arms emerging from both ends. Hubble captured this image of NGC 1022 as part of a study into black holes, which lie at the center of most (if not all) spiral galaxies like this one. — Hanneke Weitering
A volcano eruption's ashy aftermath
Friday, January 24, 2020: A new satellite view of the Taal volcano that erupted in the Philippines on Jan. 12 reveals an island that is now completely covered in a thick blanket of ash. The eruption on Luzon island blasted ash plumes 9 miles (14 kilometers) into the air, and strong winds blew large amounts of ash to neighboring regions, especially the Agoncillo area, visible southwest of the Taal volcano. The European Space Agency's Copernicus Sentinel-2 mission acquired this view of the area on Thursday (Jan. 23). — Hanneke Weitering

Also featured in this photo are two neighboring galaxies known as the Large and Small Magellanic Clouds, seen just below the Milky Way's glittering arc. — Hanneke Weitering
A Martian winter wonderland
Tuesday, January 14, 2020: Earth isn't the only planet with a frosty north pole. This image of the north pole on Mars, captured by the European Space Agency's Mars Express orbiter, shows part of the planet's polar ice cap rippled with dark-red troughs and depressions, which indicate that strong winds have been blowing in the area. Although it does not snow on Mars, storm clouds can kick dust up into the atmosphere, causing erosion that changes the appearance of the landscape over time. — Hanneke Weitering
Full Wolf Moon rising
Monday, January 13, 2020: The Full Wolf Moon rises above the frosty mountains of Macedonia in this photo taken by Stojan Stojanovski on Friday (Jan. 10).

The Swan Nebula
Thursday, January 9, 2020: The Swan Nebula, one of the biggest and brightest star forming regions in the Milky Way galaxy, only recently formed into the bird-shaped cloud we see today, new images have revealed. This composite image of the Swan Nebula combines data from NASA's flying telescope SOFIA (the Stratospheric Observatory for Infrared Astronomy), NASA's Spitzer Space Telescope and the European Space Agency's Herschel Space Telescope. In this image, astronomers discovered nine new protostars, or areas where dust and gas are collapsing to form new stars, and they were able to determine the ages of different features within the nebula.
"The central region is the oldest, most evolved and likely formed first," NASA officials said in a statement. "Next, the northern area formed, while the southern region is the youngest. Even though the northern area is older than the southern region, the radiation and stellar winds from previous generations of stars has disturbed the material there, preventing it from collapsing to form the next generation." — Hanneke Weitering

A galaxy in Berenice's Hair
Wednesday, January 1, 2020: The Hubble Space Telescope captured this stunning view of the spiral galaxy NGC 4455 in the constellation Coma Berenices, or Berenice's Hair, using its Advanced Camera for Surveys. The image was released Dec. 30. The galaxy is 45 million light-years away and its home constellation is the only star pattern to be named after an actual person from history: Queen Berenice II of Egypt.
According to ESA, Berenice was a queen of the ancient Greek city Cyrene (in what is now modern-day Libya) and later ruled Egypt after marrying its ruler, her cousin Ptolemy III Euergetes. She famously offered locks of her hair to the gods for Ptolemy's safe return from battle. — Tariq Malik
Swirls of Jupiter
Tuesday, December 31, 2019: A swirling band of clouds churns on Jupiter in this amazing image from NASA's Juno spacecraft currently orbiting the largest planet in our solar system. This image is an enhanced view by citizen scientist Björn Jónsson, who processed an image taken on Nov. 3 by Juno's JunoCam as the spacecraft was 3,200 miles (5,200 km) above Jupiter's cloudtops.

Tuesday, December 24, 2019: The spiral galaxy IC 2051, seen here in an image from the Hubble Space Telescope, is shaped like a flying saucer, with a bulge of stars at the center of its flat disk. This type of galactic bulge is believed to influence the growth of supermassive black holes that lurk at the center of most spiral galaxies, and they play a key role in how galaxies evolve. — Hanneke Weitering
Monday, December 23, 2019: Boeing's CST-100 Starliner ejects its heat shield while parachuting down to Earth before its historic landing on Sunday (Dec. 22). The uncrewed capsule touched down safely at the White Sands Missile Range in New Mexico, at 7:58 a.m. EST (1258 GMT), after spending only about 48 hours in space. It was originally scheduled to touch down six days later after a visit to the International Space Station, but Starliner never reached the orbiting laboratory after an anomaly during the launch left it in the wrong orbit. — Hanneke Weitering
Starliner Launches to Space
Friday, December 20, 2019: A United Launch Alliance Atlas V rocket carrying Boeing's CST-100 Starliner spacecraft soars into space after launching from Cape Canaveral Air Force Station in Florida this morning. Down below (from left to right), Florida Gov. Ron DeSantis, left, ULA president and CEO Tory Bruno and NASA Administrator Jim Bridenstine observe from NASA's Kennedy Space Center. The flight went according to plan until about 15 minutes after liftoff, when Starliner could not complete its orbit insertion burn due to an anomaly. Starliner was supposed to dock with the International Space Station on Saturday (Dec. 21), but it will now make an early landing on Sunday (Dec. 22) without having reached the space station. — Hanneke Weitering
A 'Candy Cane' in the Milky Way
Thursday, December 19, 2019: NASA scientists have spotted what looks like a candy cane-shaped cloud of glowing gas near the center of the Milky Way. The "candy cane" is about 190 light-years long and contains ionized gas that emits radio waves. Astronomers discovered it using an instrument known as the Goddard-IRAM Superconducting 2-Millimeter Observer, or GISMO, together with a radio telescope on Pico Veleta in Spain. You can see the full, annotated version of this image here. — Hanneke Weitering

Hubble Spots Interstellar Comet Borisov
Monday, December 16, 2019: The interstellar comet Borisov appears to come face-to-face with a distant spiral galaxy in this image from the Hubble Space Telescope. Hubble captured this image on Dec. 12, as the interstellar comet was racing through the inner solar system. At the time, the object was about 260 million miles (420 million kilometers) from Earth, while the unnamed background galaxy (officially designated 2MASX J10500165-0152029), is nearly half a billion light-years away. The galaxy appears smudged because Hubble was tracking the motion of the comet, which was zooming through space at a speed of about 109,000 mph (175,000 km/h). — Hanneke Weitering
Algae Blooms Seen from Space
Friday, December 13, 2019: Green algae blooms swirl across the Baltic Sea in this image from the European Space Agency's Copernicus Sentinel-2 satellite. The green color comes from chlorophyll in the phytoplankton, or microscopic plants that drift at the surface of the water. The chlorophyll makes these algae blooms visible from space, allowing satellites to track the tiny organisms. — Hanneke Weitering
'Cloudy with a Chance of Dust'
Thursday, December 12, 2019: Thick clouds of interstellar dust and gas permeate the star forming region RCW 36, also known as Gum 20, in this deep-space image from the European Southern Observatory's Very Large Telescope (VLT) in Chile. Located about 2,300 light-years away from Earth in the constellation of Vela (the sails), RCW 36 is part of a much larger star formation complex, known as the Vela Molecular Ridge. Astronomers used an instrument on VLT called the Focal Reducer and low dispersion Spectrograph (FORS) to capture this image of RCW 36, which is in some parts so thick with dust and gas that background light cannot pass through. These dark regions are the richest with star formation. — Hanneke Weitering
Dragon Approaches the Space Station
Wednesday, December 11, 2019: As SpaceX's Dragon CRS-19 cargo resupply ship approached the International Space Station, astronauts used the Canadarm2 robotic arm to reach out and grapple the incoming spacecraft.

The smaller telescope on the left is the 3-foot (1 meter) Schmidt telescope, which has been studying galaxies, star clusters, dwarf planets and supernovas for nearly 50 years. — Hanneke Weitering
Martian North Pole
Monday, December 2, 2019: Spiral troughs of ice and dust swirl around the Red Planet's polar ice cap in this image of the planet's north pole. Citizen scientist Kevin Gill created this map using images from the European Space Agency's Mars Express orbiter. Along with the swirling ice pattern, which scientists believe was created by winds, the image features a deep canyon known as Chasma Boreale that cuts straight through the ice cap. — Hanneke Weitering
Two Galactic Neighbors
Friday, November 29, 2019: While it's common for galaxies to coexist peacefully in the same cosmic neighborhood, these two galaxies are a bit too close for comfort. The galaxies NGC 6286 (right) and NGC 6285 (left), collectively known as Arp 293, are tugging at each other with their mutually strong gravitational attraction, dragging wisps of gas and dust out from the galaxies and into interstellar space. This causes the galaxies to appear "smudged" and blurred from our perspective on Earth. The Hubble Space Telescope captured this image of the galactic pair, which are located more than over 250 million light-years from Earth in the constellation Draco. — Hanneke Weitering
Spacewalker Floats Above the Clouds
Wednesday, November 27, 2019: With his special space camera in hand, NASA astronaut Drew Morgan is seen working outside the International Space Station during his spacewalk with European Space Agency astronaut Luca Parmitano on Nov. 22.

Hubble Eyes an Emission Galaxy
Tuesday, November 26, 2019: Looming some 135 million light-years from Earth in the constellation of Centaurus is the bright emission line galaxy NGC 3749, seen here in an image from the Hubble Space Telescope. Astronomers can learn a lot about a galaxy by studying its spectrum of light, particularly the wavelengths of light that are emitted or absorbed by elements it contains. NGC 3749 displays strong emission lines, which means that it is "bursting with star formation and energetic stellar newborns," the European Space Agency said in a statement. — Hanneke Weitering
Orion Enters the Super Guppy
Monday, November 25, 2019: NASA's Orion spacecraft is loaded inside the belly of the Super Guppy aircraft at the Launch and Landing Facility runway at Kennedy Space Center in Florida, on Nov. 21.

You can watch it live here on Space.com. — Hanneke Weitering
Hubble Spots a Strange Spiral Galaxy
Thursday, November 21, 2019: The spiral galaxy NGC 772, seen here in a new image from the Hubble Space Telescope, bears some striking similarities to the Milky Way galaxy that we call home, with its spiral arms, glowing core and dark dust lanes. But there are some key differences between NGC 772 and the Milky Way.
For one, NGC 772 lacks the kind of bar-shaped structure of stars like the one that stretches across the center of the Milky Way. NGC 772 is classified as a peculiar, unbarred spiral galaxy, which means that it is "somewhat odd in size, shape or composition," according to NASA. Located about 130 million light-years away from Earth in the constellation Aries, NGC 772 is about twice the size of the Milky Way. — Hanneke Weitering
Bye Bye, Debris Shield!
Wednesday, November 20, 2019: The debris shield that once protected NASA's Alpha Magnetic Spectrometer from micrometeoroid impacts floats away from the International Space Station after two astronauts removed it and flung it into space during a spacewalk on Nov. 15. European Space Agency astronaut Luca Parmitano used special tools to remove 13 screws and 10 fasteners to release the debris shield, after which NASA astronaut Drew Morgan jettisoned the shield, tossing it toward Earth to burn up in the atmosphere. This was the first of four spacewalks that these two astronauts are conducting to repair the ailing particle detector experiment, which was not designed to be serviced by astronauts in orbit, making these some of the most challenging spacewalks ever. — Hanneke Weitering
A Vista Under the Milky Way
Tuesday, November 19, 2019: The Milky Way glistens above the Visible and Infrared Survey Telescope for Astronomy (VISTA) at the Paranal Observatory in northern Chile in this stunning night-sky view by European Southern Observatory photo ambassador Babak Tafreshi.

Lunar Halo Over La Silla
Friday, November 15, 2019: A lunar "halo" lights up the night sky above the 3.6-meter telescope at the La Silla Observatory in Chile. This phenomenon happens when the moon is at an altitude of about 22 degrees above the horizon, where light refracts through icy cirrus clouds. "Light rays that do this tend to 'bunch up' at the angle that represents the least amount of deviation from their original path. For the particular shape of ice crystal lurking within the cirrus clouds, this minimum deviation angle happens to be around 22 degrees," ESO officials said in a description. — Hanneke Weitering
Apollo 12: A Happy Moon Return

It will spend 5 hours and 28 minutes traveling across the face of the sun today, and you can watch it live online. — Hanneke Weitering
Hubble Spots a Cosmic Kaleidoscope
Friday, November 8, 2019: When the Hubble Space Telescope turned its gaze toward the remote galaxy known as the "Sunburst Arc," it saw not one but 12 separate images of the lone cosmic object. That's because there's a massive galaxy cluster in the foreground warping the light with its intense gravitational pull. This illusion is known as gravitational lensing, a phenomenon that Albert Einstein first described in his theory of general relativity. "This 'funhouse mirror' effect not only stretches the background galaxy image, but also creates multiple images of the same galaxy," NASA officials said in a statement. — Hanneke Weitering
A Jovian Marble
Thursday, November 7, 2019: Jupiter looks like a big, swirly space marble in this composite image from NASA's Juno spacecraft.
