Two ringlike structures of stars wrapping around the Milky Way's outer disk now appear to belong to the disk itself. The results, outlined in a new study, show that the disk is about 60 percent ...

That’s exactly what happened earlier this year, when a team of astronomers serendipitously observed a population of 47 Milky Way-size, weirdo galaxies living very far from home. Unexpectedly ...

Our Galactic home just got a remodel. Peering through the dust and gas that intersperse our Galaxy, astronomers have found that the Milky Way’s core is less dense than originally thought.

The Milky Way’s bigger mass does mean a greater chance of a gravity-driven collision with Andromeda. But if that clash occurs, at least now we’re in the same weight-class. On supporting ...

Most galaxies are thought to have a supermassive black hole at their centres, but proving it is very difficult. The centre of our own Galaxy, occupied by the compact radio source Sagittarius A* ...

To find the Milky Way’s edge, Deason’s team conducted computer simulations of how giant galaxies like the Milky Way form. In particular, the scientists sought cases where two giant galaxies ...

When Peter Predehl, an astrophysicist at the Max Planck Institute for Extraterrestrial Physics in Germany, first laid eyes on the new map of the universe’s hottest objects, he immediately recognized ...
