A discovery of so-called barred galaxies early in the universe will require astrophysicists to refine their theories of galaxy evolution.

Researchers have created millions of simulated galaxies to find out how black holes grow with their galaxies.

Images from the James Webb Space Telescope show what might be one of the earliest galaxies ever discovered, researchers report.

A Stanford astrophysicist and cosmologist reacts to recent news about the image taken by the James Webb Space Telescope.

The answer to a complex mystery may involve a chaotic triple drama inside a giant disk of gas around a super massive black hole in a galaxy far, far away.

Simulations show some galaxies lose their dark matter in collisions. They show how galaxies can exist without dark matter, once thought impossibe.

Astrophysicist Andrea Ghez discovered the black hole at the heart of the Milky Way. Here, she explains the monster at the center of our galaxy.

"The invisible galaxies that we've discovered in the early universe are some of the first building blocks of the mature galaxies we see around us..."

The first observation of a cosmic boomerang effect offers new insights into how galaxies grow, live, and die.

A new map of what researchers call the "cosmic web" shows the dark matter in the local universe and reveals hidden "bridges" between galaxies.
