Sagittarius A* may be a dense dark matter core instead of a black hole, offering a new explanation for the Milky Way’s central gravity.

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 ...

An invisible monster lurks beyond the stars of the constellation Sagittarius near the border with Scorpius: a supermassive black hole, designated as Sagittarius A* (pronounced “Sagittarius A-star”), ...

Scientists hope to probe the nature of general relativity through a possible pulsar found in the center of the Milky Way, ...

Nico Cappelluti, an associate professor in the department of physics at the University of Miami, said that the Fermi telescope has been a game changer for NASA, and this paper shows that dark matter ...

August continues to be a great month to check out the skies. This month offers one of the best opportunities to see the Milky Way. The center of our galaxy is teeming with billions of stars that ...

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.

At the center of our galaxy, there’s a mysterious, diffuse glow given off by gamma rays — powerful radiation usually emitted by high-energy objects such as rapidly rotating or exploding stars. NASA’s ...
