galaxies

The cores of galaxies may not be made of what we thought, new research suggests — they could hold one giant, invisible star made of mysterious "fuzzy" matter.

In this special Hubble image 23 years in the making, the sparkling spiral galaxy UGC 10043 reveals the secrets of its unusually big bulge.

A new effort to map the rumblings in spacetime caused by enormous black hole collisions paints a surprisingly loud and lopsided picture of the universe.

There's a cosmic 'Christmas Wreath' hanging in the Small Magellanic Cloud, the James Webb and Chandra telescopes revealed in a sparkly new image.

This week, the James Webb Space Telescope zooms in on the iconic Sombrero Galaxy, revealing the first-ever mid-infrared observations of the hat-shaped wonder.

The Hubble Space Telescope captured an image of NGC 4694, a galaxy that possesses unusual properties that complicate its classification.

The James Webb Space Telescope's discovery of unusually bright and massive galaxies soon after the Big Bang has cast doubt on the standard model of galaxy evolution and bolstered a rival theory for how physics may work on large scales, according to a team of astronomers.

The James Webb telescope has spotted three gigantic "red monster" galaxies that were spawned soon after the Big Bang. They're so large they could rewrite the laws of galactic evolution.

The number of known galaxies circling the Milky Way is increasing as we develop new powerful telescopes.

The Hubble Space Telescope has captured a spiral galaxy under the "ram pressure" inside a massive cluster of galaxies.
