JWST has identified nine distant, compact galaxies that do not fit existing categories, raising new questions about how galaxies formed in the early Universe.

Dozens of dwarf galaxies swarming around the Andromeda Galaxy like bees have been caught on camera by the Hubble Space Telescope, which took more than a thousand orbits of the Earth to take enough ...

Astronomers have identified Cloud 9, a nearby dark matter halo filled with gas but no stars. The discovery supports key predictions about how galaxies form and why some never do.

Scientists have found a remarkably small yet bright object from the early universe that doesn’t make sense in our existing models of how stars and galaxies formed, even our own Milky Way. That means ...

Astronomers may have uncovered the origins of the mysterious “little red dots,” some of the strangest galaxies seen in the early universe. These tiny but brilliant objects, discovered by the James ...

Structures known as "zippers" and "twisters" in the early universe may explain why dwarf galaxies tend to line up with each other, as well as hint at how dark matter operates in the universe. When you ...

Three merging galaxies host three active black holes, offering rare insight into galaxy and black hole growth.

Scientists have detected oxygen in the most distant galaxy ever found, suggesting that early galaxies formed more rapidly than previously thought. The record-breaking discovery, reported by two teams ...

Galaxies like the Milky Way boast more than spirals; they also have feathers, where clumps of new stars are born. Astronomers ...
