NASA’s Roman to Peer Into Cosmic ‘Lenses’ to Better Define Dark Matter

A funky effect Einstein predicted, known as gravitational lensing — when a foreground galaxy magnifies more distant galaxies behind it — will soon become common when NASA’s Nancy Grace Roman Space Telescope begins science operations in 2027 and produces vast surveys of the cosmos.

NASA’s Webb ‘UNCOVERs’ Galaxy Population Driving Cosmic Renovation

Astronomers using data from NASA’s James Webb Space Telescope have identified dozens of small galaxies that played a starring role in a cosmic makeover that transformed the early universe into the one we know today. “When it comes to producing ultraviolet light, these small galaxies punch well above their weight,” said Isak Wold, an assistant […]

Webb Sees Sombrero Galaxy in Near-Infrared

After capturing an image of the iconic Sombrero galaxy at mid-infrared wavelengths in late 2024, NASA’s James Webb Space Telescope has now followed up with an observation in the near-infrared.

Hubble Captures Starry Spectacle

A galaxy ablaze with young stars is the subject of this NASA/ESA Hubble Space Telescope image. Named NGC 685, this galaxy is situated about 64 million light-years away in the constellation Eridanus (the River). NGC 685 is a barred spiral because its feathery spiral arms sprout from the ends of a bar of stars at […]

Hubble Captures Cotton Candy Clouds

This NASA/ESA Hubble Space Telescope image features a sparkling cloudscape from one of the Milky Way’s galactic neighbors, a dwarf galaxy called the Large Magellanic Cloud. Located 160,000 light-years away in the constellations Dorado and Mensa, the Large Magellanic Cloud is the largest of the Milky Way’s many small satellite galaxies.

Galaxy Clusters on Course to Crash Again, NASA’s Chandra Finds

New observations from NASA’s Chandra X-ray Observatory and other telescopes have captured a rare cosmic event: two galaxy clusters have collided and are now poised to head back for another swipe at each other. Galaxy clusters are some of the largest structures in the Universe.

NASA’s Webb Rounds Out Picture of Sombrero Galaxy’s Disk

After capturing an image of the iconic Sombrero galaxy at mid-infrared wavelengths in late 2024, NASA’s James Webb Space Telescope has now followed up with an observation in the near-infrared. In the newest image, the Sombrero galaxy’s huge bulge, the tightly packed group of stars at the galaxy’s center, is illuminated, while the dust in […]

Hubble Filters a Barred Spiral

This NASA/ESA Hubble Space Telescope image features a luminous tangle of stars and dust called the barred spiral galaxy NGC 1385, located about 30 million light-years away. Hubble released an earlier image of NGC 1385, but the two images are notably different. This more recent image has far more pinkish-red and umber shades, whereas cool […]

Apocalypse When? Hubble Casts Doubt on Certainty of Galactic Collision

As far back as 1912, astronomers realized that the Andromeda galaxy — then thought to be only a nebula — was headed our way. A century later, astronomers using NASA’s Hubble Space Telescope were able to measure the sideways motion of Andromeda and found it was so negligible that an eventual head-on collision with the […]

Hubble Spies Paired Pinwheel on Its Own

A single member of a galaxy pair takes centerstage in this NASA/ESA Hubble Space Telescope image. This beautiful spiral galaxy is NGC 3507, which is situated about 46 million light-years away in the constellation Leo (the Lion). NGC 3507’s classification is a barred spiral because the galaxy’s sweeping spiral arms emerge from the ends of […]
