The Milky Way has just been reconstructed in unprecedented detail, with artificial intelligence helping astronomers track the motions and histories of roughly 100 billion stars inside a single digital ...

Astronomers have discovered a flattened structure of matter around the Milky Way that explains the unusual motion of nearby galaxies.

Add Yahoo as a preferred source to see more of our stories on Google. Artistic representation of the Milky Way, where the innermost stars move at near relativistic speeds (defined as velocities that ...

For decades, astronomers wondered why most nearby galaxies are speeding away from the Milky Way instead of being pulled in by its gravity. New simulations reveal the answer: our galaxy sits in a ...

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 ...

There are excesses of gamma-ray emissions from the center of the Milky Way that are not fully understood. It has been hypothesized that dark matter could be responsible for it, though there has not ...

Astronomers from the University of Groningen have discovered that the Milky Way does not move in the cosmic void, but is embedded in a flat "sheet" of dark matter. This was reported on March 11 in the ...

For billions of years before reaching its current location, the Sun may have slowly travelled as part of a large group, or “wave,” of stars drifting out from the inner parts of the Milky Way. This ...

Billions of stars fill our galaxy that become visible at certain times of year. And in the U.S., that time, known as "Milky Way season," is beginning.

Most of the (dark) matter beyond the Local Group of galaxies (which includes the Milky Way and the Andromeda Galaxy) must be ...
