Previous observations of stars whipping around an unseen mass—especially a bright star called S2—have pointed to an object ...

A new gravitational model suggests dark matter may not exist. By allowing gravity to weaken more slowly at large distances, physicist Naman Kumar shows galaxy rotation curves can be explained using ...

What if the Milky Way’s central “black hole” isn’t a black hole at all? A new model proposes that an ultra-dense dark matter core could mimic its gravitational pull.

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

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

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

According to their model, this dark matter would naturally form a two-part structure: an extremely dense central core ...

For decades, the motions of stars near the center of our Milky Way Galaxy have been treated as some of the clearest evidence ...

Our Milky Way galaxy may not have a supermassive black hole at its center but rather an enormous clump of mysterious dark ...
