early galaxies

How did supermassive black holes form? JWST and Chandra may have found the answer.

The James Webb Space Telescope has observed galaxies defying the "cosmic rulebook" in the early universe, to the surprise of astronomers who hope to learn more about the evolution of the universe.

To mark a year of James Webb Space Telescope observations, NASA astrophysicist Taylor Hutchinson spoke about the powerful telescope's impact on space science and what might lie ahead.

The most luminous galaxy known appears to have devoured three smaller galaxies at the same time, revealing details about why it shone so brightly.

It may seem like we've got the universe pretty much figured out, but there is some pretty basic stuff that we just don't have a clue about.

Although the invisible substance known as dark matter dominates galaxies nowadays, it was apparently only a minor ingredient of galaxies in the early universe, a new study finds.

Some of the most distant clusters of galaxies ever discovered are producing baby stars at higher rates than closer galaxy clusters, and scientists aren't sure why.

Early galaxies are shining light on a decades-old mystery, helping to clear up the size and composition of the clouds of gas responsible for forming their neighbors.
