James Webb spotted a young galaxy blasting away its star-forming gas, revealing how massive galaxies may die early.

If a galaxy runs out of gas, it will stop forming stars and die. Present-day galaxies have had more than 10 billion years to ...

Astronomers have discovered a powerful “galaxy-killing wind” in the early universe that may help solve one of the biggest ...

Image of the Kinman Dwarf galaxy taken with the NASA/ESA Hubble Space Telescope’s Wide Field Camera 3 in 2011, before the disappearance of the massive star. (NASA, ESA / Hubble, J. Andrews, University ...

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 ...

JWST observations show that early galaxies were chaotic, gas-filled systems rather than stable disks. Researchers from Cambridge studied over 250 galaxies and found most were turbulent, still forming ...

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 ...

The James Webb Space Telescope (JWST) is the largest and most powerful space telescope built to date. Since it was launched in December 2021 it has provided groundbreaking insights. These include ...

The Milky Way could have many more satellite galaxies than scientists have previously been able to predict or observe, according to new research. Cosmologists at Durham University used a new technique ...
