The object at the Milky Way’s center has long been treated as a settled case: a supermassive black hole called Sagittarius A* ...

New research suggests that the heart of the Milky Way may be dominated by a dense clump of dark matter rather than the ...

Astronomers overwhelmingly agree a supermassive black hole anchors the Milky Way. But a new theoretical analysis explores a far more speculative possibility: not a black hole, but a dense knot of dark ...

Astronomers propose that an ultra-dense clump of exotic dark matter could be masquerading as the powerful object thought to ...

There is a lot we have yet to understand about the center of the Milky Way—could it be due to a mass of invisible dark matter?

New data from the James Webb Space Telescope may solve a riddle from the universe’s beginnings. A compact, distant object called “The Cliff” appears to show that many of the mysterious “little red ...

One of the brightest stars in the Andromeda galaxy has disappeared without the explosion astronomers expected. Instead, they ...
