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.

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 ...

A team of astronomers led by researchers at the University of Groningen has identified a colossal sheet of dark matter and ...

TROY, N.Y. – Heidi Jo Newberg, associate professor of physics at Rensselaer Polytechnic Institute, and Brian Yanny, an astrophysicist at Fermi National Accelerator Laboratory, who are leading a team ...

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 ...

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 ...

Our home galaxy might be larger than we first assumed, astronomers have found. A new model of the Milky Way has revealed that our galaxy is wider than we thought, according to a new paper in the ...

The Milky Way is our home galaxy with a disc of stars that spans more than 100,000 light-years. While the Milky Way is generally always visible from Earth, certain times of year are better for ...

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 ...
