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 ...

An international research team has found that the Milky Way and its galactic neighbors appear to sit inside a vast, flat concentration of dark matter, a structure stretching roughly 10 megaparsecs and ...

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 ...

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 ...

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 ...

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 ...

Scientists in China have developed an AI model that analyzes stellar data from different telescopes, helping astronomers combine survey data.

Forbes contributors publish independent expert analyses and insights. An award-winning reporter writing about stargazing and the night sky. When will the Milky Way collide with the Andromeda Galaxy?

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 ...
