Over the past decade, the shadow of a black hole in M87 has been wobbling, which tells us about how matter behaves near a black hole.
The Destruction of Dark Matter isn’t Causing Extra Radiation at the Core of the Milky Way
While recent studies suggest that dark matter interactions might create gamma rays, a new study of gamma rays in our galaxy throws shade on that idea.

Fastest Star Ever Seen is Moving at 8% the Speed of Light
A star orbiting the black hole in the center of our galaxy is moving so fast it can only be described relativistically.
Why Can Black Hole Binaries Have Dramatically Different Masses? Multiple Generations of Mergers
Black hole mergers with very different masses tell us how small mergers can give rise to even larger ones.
The Universe is the Same, Everywhere We Look. Even More than Cosmologists Predicted
The Universe is about 10% smoother than we expect, and astronomers aren’t entirely sure why.
