Our Milky Way galaxy may not have a supermassive black hole at its center but rather an enormous clump of mysterious dark matter exerting the same gravitational influence, astronomers say. They ...

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.

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

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 ...

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

At the center of our galaxy, something incredibly heavy is pulling the strings. Stars ...

Astronomers propose that an ultra-dense clump of exotic dark matter could be masquerading as the powerful object thought to anchor our galaxy, explaining both the blistering speeds of stars near the ...

Saul Hernandez, a New Mexico State University senior studying physics and linguistics with a minor in astronomy, has turned recycled materials into a backyard radio telescope capable of detecting the ...

Researchers discover high-velocity clouds in the nearby spiral galaxy M83. These clouds are moving at speeds significantly different to the galaxy’s overall speed of rotation. The findings suggest ...
