Located 2.5 million light-years away, the majestic Andromeda galaxy appears to the naked eye as a faint, spindle-shaped object roughly the angular size of the full Moon. What backyard observers don’t see is a swarm of nearly three dozen small satellite galaxies circling the Andromeda galaxy, like bees around a hive.

The sparkling spiral galaxy gracing this NASA/ESA Hubble Space Telescope image is UGC 5460, which sits about 60 million light-years away in the constellation Ursa Major. This image combines four different wavelengths of light to reveal UGC 5460’s central bar of stars, winding spiral arms, and bright blue star clusters.

Where is all the water that may form oceans on distant planets and moons? The SPHEREx astrophysics mission will search the galaxy and take stock. Every living organism on Earth needs water to survive, so scientists searching for life outside our solar system, are often guided by the phrase “follow the water.” Scheduled to launch […]

Discovery proves decades-old theory of galaxy feeding cycle. Researchers using NASA’s James Webb Space Telescope have finally solved the mystery of how a massive galaxy cluster is forming stars at such a high rate.

A supernova and its host galaxy are the subject of this NASA/ESA Hubble Space Telescope image. The galaxy in question is LEDA 132905 in the constellation Sculptor. Even at more than 400 million light-years away, LEDA 132905’s spiral structure is faintly visible, as are patches of bright blue stars. The bright pinkish-white dot in the […]

This image from NASA’s Hubble Space Telescope, released on Feb. 4, 2025, shows the gargantuan galaxy LEDA 1313424, aptly nicknamed the Bullseye. A far smaller blue dwarf galaxy went through the Bullseye’s center, leaving nine star-filled rings.

Shaped like a megaphone, the upcoming mission will map the entire sky in infrared light to answer big questions about the universe. Expected to launch no earlier than Thursday, Feb. 27, from Vandenberg Space Force Base in California, NASA’s SPHEREx space observatory will provide astronomers with a big-picture view of the cosmos like none before.

The subject of this NASA/ESA Hubble Space Telescope image is a supernova-hosting galaxy located about 600 million light-years away in the constellation Gemini. Hubble captured this image roughly two months after a supernova named SN 2022aajn was discovered. The supernova is visible as a blue dot at the center of the image, brightening the hazy […]

Supermassive Black Holes
Astronomers have taken a crucial step in showing that the most massive black holes in the universe can create their own meals. Data from NASA’s Chandra X-ray Observatory and the Very Large Telescope (VLT) provide new evidence that outbursts from black holes can help cool down gas to feed themselves. This study was based on […]
