Give them a constellation prize. A group of international scientists discovered three ultra-massive “Red Monster” galaxies capable of forming their own stars faster than the average nebula. The ...

An international team of astronomers has identified three ultra-massive galaxies—each nearly as massive as the Milky Way—already in place within the first billion years after the Big Bang. The ...

Cosmic dawn galaxies seen by JWST reveal hidden clues about dark matter and keep rival theories about its true nature alive.

Galaxies like our Milky Way grew through cascading mergers of smaller galaxies that began billions of years ago. The ancient ...

Researchers have found a razor-thin, rotating string of galaxies inside a massive cosmic filament, revealing unexpected ...

The discovery reinforces established theories about space. There could be many more satellite galaxies orbiting the Milky Way than previously thought or observed, according to astronomers. As many as ...

The discovery included 30,000 examples of the rarest known galaxy shape. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. Citizen scientists and ...

New supercomputer simulations suggest the Milky Way could be surrounded by dozens more faint, undetected satellite galaxies—up to 100 more than we currently know. These elusive "orphan" galaxies have ...

Scientists are peering into the past and uncovering new clues about the early universe. Since light takes a long time to travel through space, they are now able to see how galaxies looked billions of ...

The Euclid space telescope team has released its first science images. They show sparkling clusters of galaxies, an astonishingly sharp image of a nearby spiral galaxy and a colourful cloud of ...

In fact, these jets often expand into wide plumes or “lobes” that fan out far above and below their host galaxies. The jets ...

Most smaller galaxies may not have supermassive black holes in their centers, according to a recent study using NASA's Chandra X-ray Observatory. This contrasts with the common idea that nearly every ...
