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 ...

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 ...

Two colliding galaxies have been found to be reorganizing their dwarf satellites, potentially solving a major conundrum plaguing the standard model of cosmology. New observations of a pair of ...

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 ...

Only a fraction of the size of the Milky Way, these galaxies have thus far been too faint for most telescopes to spot. Among the hundreds of billions of galaxies that stretch across the known universe ...

Scientists have observed the largest-known rotating structure in the cosmos - a gargantuan thread-like assemblage of hundreds ...

Most smaller galaxies may not have supermassive black holes in their centers, according to a recent study using NASA's ...

A potential polar ring galaxy called NGC 4632. The composite image combines a capture of the galaxy's main disk, taken with the Subaru Telescope, with radio wave data of the hydrogen ring, which has ...

More than 100 observed galaxies are being disrupted and stripped of their outer layers, transforming them into fossil-dense, ultra-compact dwarf galaxies. When you purchase through links on our site, ...

An international team led by the University of Oxford has identified one of the largest rotating structures ever reported: a ...

The Supergalactic Plane we are located in doesn't have many spiral galaxies like the Milky Way. Astronomers think they finally know why galaxies like ours are so rare. When you purchase through links ...
