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 ...

An international team of scientists has unveiled the largest and most detailed map of the universe ever created using the James Webb Space Telescope, revealing nearly 800,000 galaxies stretching back ...

An inexplicably hot, fast-growing cluster of galaxies in the early universe has scientists questioning theories of galactic evolution.

Astronomers have completed the most comprehensive census of active galactic nuclei (AGN) to date, providing the clearest ...

Only a fraction of the size of the Milky Way, these galaxies have thus far been too faint for most telescopes to spot. When you purchase through links on our site, we may earn an affiliate commission.

Located billions of light-years away, the "Cosmic Owl" is a pair of colliding ring galaxies spotted by the JWST. It's also an "exceptional natural laboratory" for studying how galaxies evolve. When ...

Astronomers using NASA’s James Webb Space Telescope have stumbled upon a puzzling population of galaxies that look far too bright for their age. In four patches of sky, covering more than 500 square ...

A whole universe of hidden galaxies lies just beyond what the eye can see. Thanks to a new generation of space telescopes, astronomers are now revealing these distant, dim worlds—some no bigger than a ...

An international team led by the University of Oxford has identified one of the largest rotating structures ever reported: a "razor-thin" string of galaxies embedded in a giant spinning cosmic ...

Radio telescopes have long scanned quiet patches of sky for a lone, artificial-sounding ping, but a growing body of research is pushing astronomers to look instead at the loudest neighborhoods in the ...
