New models could inform researchers working to get the very first picture of Sagittarius A*, the supermassive black hole at the Milky Way's center.

Researchers have solved a decades-old mystery of "missing matter"—material long predicted to exist in the universe but never detected—until now.

Cosmologists had only been able to find half the matter that should exist in the universe. With the discovery of a new astronomical phenomenon and new telescopes, researchers just found the rest.

Satellite galaxies orbiting the Milky Way galaxy may give researchers insight into dark matter and even the origins of our universe.

New techniques are being used to transform images from Hubble into spectacular 3D visualisations.

The Milky Way may be catapulting stars into its outer galactic halo, researchers say. The finding could change how we think about how star systems are born.

In the search for elusive dark matter, even a setback can open up new paths forward.

"This is the first time we have been able to determine when such a merger happened."

Researchers have nailed down the origin of a fast radio burst from space, but their discovery also adds to the mystery of FRBs.
