galaxies

Astronomers have long predicted that a collision between our galaxy and nearby Andromeda could be inevitable, but new calculations suggest this may be an over exaggeration.

If we can see at most 3% of the universe, how can we estimate the total number of galaxies in it?

To mark its second anniversary of operations, James Webb Space Telescope scientists share a stunning view of the Penguin and Egg galaxies as they slowly collide.

Using the James Webb Space Telescope, astronomers have witnessed the dramatic dance between a supermassive black hole-powered quasar and merging galaxies less than a billion years after the Big Bang.

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.
