The James Webb Space Telescope found "tiny red dots" in the early universe representing overgrown supermassive black holes and stars that are impossibly old for the infant cosmos.

Astronomers have just discovered two dwarf galaxy candidates orbiting our galaxy. The orientation of these entities suggests there could be up to 500 similar stellar clusters circling the Milky Way, which is more than double previous estimates.

Astronomers using the James Webb Space Telescope have observed five extremely dense proto-globular clusters along a hair-thin arc of glittering stars. The discovery could help them understand how the earliest galaxies formed.

The sparkling galaxy NGC 1546 stars in Hubble's first new image since changing to its new "one-gyro mode," ending the telescope's roughly month-long break.

Astronomers may be watching a supermassive black hole "waking up" from a long slumber for the first time ever. The researchers think the black hole may have gotten its hands on a glut of new material to devour, causing an uptick in brightness.

Scientists recently identified seven stars in the Milky Way that could potentially be gigantic alien structures called Dyson spheres. New research proposes an alternative explanation: Those are just cosmic "hot DOGs" in disguise.

The James Webb Space Telescope has found carbon in a galaxy just 350 million years after the Big Bang. That could mean life began much earlier too, a new study argues.

The James Webb Space Telescope peers into NGC 4449, a small galaxy showing explosive star formation that astronomers can't quite explain.

The James Webb Space Telescope may have spotted the birth of some of the earliest galaxies in the universe for the first time ever, new research hints.

The Hubble Space Telescope's stunning image of the dusty 'train-wreck' galaxy NGC 4753 reveals what may be one of the greatest optical illusions in the nearby universe.
