"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

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
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
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
First responders honored in space
Monday, May 11, 2020: To honor the frontline medical workers of the COVID-19 pandemic on the 75th anniversary of Victory in Europe Day, which marked the end of World War II in Europe, NASA astronaut Andrew Morgan tweeted this photo of a WWII medical armband floating in the Cupola observatory of the International Space Station.
"Much like first responders on the frontlines today, 75 years ago combat medics bravely faced grave danger to save fellow #Soldiers on the battlefield," Morgan tweeted May 8. "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
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
So long, Cygnus!
Wednesday, May 13, 2020: Northrop Grumman's Cygnus NG-13 cargo resupply spacecraft, with its shiny, cymbal-shaped solar arrays, is pictured in the grasp of the Canadarm2 robot arm on the International Space Station just before the vessel's departure on Monday (May 11). 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
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
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 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
Milky Way meets the zodiacal light
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

On board will be Bob Behnken and Doug Hurley, who will become the first NASA astronauts to travel to the International Space Station in a commercial spacecraft. SpaceX founder Elon Musk tweeted this photo on Tuesday night (May 26). — 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
