Go behind the scenes with the James Webb Space Telescope, the most powerful observatory ever launched, as it reveals secrets ...

Researchers led by a Rutgers University-New Brunswick astrophysicist, who looked deeply into space at a period known as "Cosmic Noon," about 2 billion to 3 billion years after the Big Bang, have found ...

Astronomers at Durham University have made a major advance in understanding how galaxies formed and evolved in the early ...

Distant galaxies that abruptly stopped making stars have puzzled astronomers for years. About 9 billion years ago, during one ...

A ghostlike particle from deep space sent astronomers chasing one of the Universe’s hardest mysteries. The trail led somewhere unexpected.

New supercomputer simulations suggest the Milky Way could be surrounded by dozens more faint, undetected satellite galaxies—up to 100 more than we currently know. These elusive "orphan" galaxies have ...

These three galaxy images from the AEGIS survey show a range of galaxy types: a disk-like spiral galaxy (top), a cloud-like elliptical galaxy (middle), and an irregular galaxy resulting from a ...

Astronomers used the James Webb Space Telescope to observe CRISTAL-02 and discovered a galaxy-killing wind.

Abstract : Weighing in at 1042 kilograms and measuring 1021 meters across, galaxies are perhaps the most awe-inspiring objects known to mankind. They are also the only places in an otherwise dark and ...

The formation and evolution of galaxies are governed by the processes that assemble their mass and regulate the conversion of gas into stars. Over cosmic history, galaxies grow through the accretion ...

What does it mean to find a galaxy without dark matter, or with very little of it?
