There are billions upon billions of galaxies in our universe, but only a handful have common names — and some of them might surprise you.

An international team of astronomers has identified three ultra-massive galaxies—each nearly as massive as the Milky Way—already in place within the first billion years after the Big Bang. The ...

Researchers say a cosmic collision could have created two galaxies that don’t contain the mysterious substance — but others cast doubt on the claim.

Scientists are peering into the past and uncovering new clues about the early universe. Since light takes a long time to travel through space, they are now able to see how galaxies looked billions ...

Early galaxies were not too big for their britches after all Astronomers can explain some surprising recent discoveries Date: August 26, 2024 Source: University of Texas at Austin Summary ...

Star-forming galaxies trace cosmic history. Recent observational progress has led to the discovery and study of the earliest known galaxies, corresponding to a period when the Universe was only ...

Only a fraction of the size of the Milky Way, these galaxies have thus far been too faint for most telescopes to spot.

As galaxies collide and new stars are born, spectacular shapes form in the universe—and many of them resemble Earthly creatures.

Smaller, because galaxies merge together and attract more matter over time, and Less spiral-like, because we are only seeing the brightest parts of the most active, star-forming galaxies.

A technique used to reveal dark matter could also shed light on a disagreement about the clumpiness of matter in the cosmos.

Astronomers using a huge radio telescope in South Africa have found two of the largest known single objects in the Universe. About 22 times larger than our Milky Way, these “giant radio galaxies ...
