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 ...

NEW YORK (AP) — A European space telescope launched to explore the dark universe has released a trove of new data on distant galaxies. READ MORE: A cradle of baby stars revealed in new European space ...

According to a new study, some of the earliest galaxies observed with the James Webb Space Telescope are in fact much less massive than they first appeared. Black holes in some of these galaxies make ...

Astronomers using the James Webb Space Telescope (JWST) have captured the most detailed look yet at how galaxies formed just a few hundred million years after the Big Bang—and found they were far more ...

Astronomers have spotted a pair of galaxies in the act of merging 12.8 billion years ago. The characteristics of these galaxies indicate that the merger will form a monster galaxy, one of the ...

Bringing us one step closer to solving the 'missing satellites problem,' researchers have discovered two new satellite galaxies. For years, astronomers have worried about how to explain why the Milky ...

Two far-away galaxies have been described as “blood-soaked eyes” by NASA after the Hubble and James Webb Space telescopes captured an intriguing video of the two colliding galaxies. NASA says the ...

Galaxies speckle the heavens like stars in a stunning new photo of the deep and distant universe. The James Webb Space Telescope (JWST) team shared a new image of a region of the sky called the COSMOS ...

Astrophysicists have been exploring the mystery of UFOs—no, not the "little green men" ones, but a strange type of large galaxy dubbed "Ultra-red Flattened Objects." First discovered by University of ...

Spiral galaxies imaged by JWST that rotate in the same direction relative to the Milky Way (red) and in the opposite direction relative to the Milky Way (blue). The number of galaxies rotating in the ...

The James Webb Space Telescope caught a glimpse of these violent bundles of gas and stars. The universe's first galaxies were hot messes, according to a recent study. During their younger days, they ...
