There could be many more satellite galaxies orbiting the Milky Way than previously thought or observed, according to astronomers.

While we have plenty of spiral galaxies, like our own Milky Way, these are only the most common types of galaxies out there. There are still others, like elliptical or irregular galaxies.

A whole universe of hidden galaxies lies just beyond what the eye can see. Thanks to a new generation of space telescopes, astronomers are now revealing these distant, dim worlds—some no bigger than a ...

The James Webb Space Telescope’s first picture released to the public showed off thousands of galaxies. At first glance, the pinpoints of light shining in the blackness of space look like little ...

Astronomers have used the Atacama Large Millimeter/submillimeter Array (ALMA) to peer into the early universe and uncover the ...

Spiral galaxies like our own are just one type, and each galaxy variant can come in a variety of sizes. These new galaxies are what are known as UCDs, or ultra-compact dwarf galaxies.

In its debut, the telescope turned its eye toward two familiar showstoppers in deep space: the Trifid and Lagoon nebulas in ...

This was surprising, as the researchers previously thought that FRBs occurred equally in all types of galaxies. This also suggests that if FRBs are more common in massive galaxies, so are magnetars.
