Travel back 390 million years after the big bang to the ancient Maisie's Galaxy in this stunning 3D visualization that ...

Hidden deep in space, the Great Attractor is a gravitational anomaly so powerful it drags entire galaxies toward it, ...

There could be many more satellite galaxies orbiting the Milky Way than previously thought or observed, according to astronomers. As many as 100 undiscovered galaxies that are too faint to be seen ...

The project, dubbed MIDIS for short, found nearly 2,500 light sources, most of them distant galaxies. About 1,000 now have revised distance estimates, based on how their light has shifted.

The first test images from the Vera C. Rubin Observatory in Chile showcase thousands of previously unknown asteroids and millions of glittering galaxies.

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 ...

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 ...

The team points to 30 recently discovered objects that could be satellite galaxies of the Milky Way, suggesting they could be a subset of the orphan galaxies predicted in this research.

Compact ruddy galaxies (six shown in these images from the James Webb Space Telescope) known as little red dots may have originated in slowly spinning dark matter halos, astronomers say. Dale ...

The Andromeda galaxy lies just beyond (...OK, about 2.5 million light-years beyond) our galaxy, the Milky Way. These galaxies are more than just neighbors: They're gravitationally bound. And for ...
