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

At the center of the Milky Way, a supermassive black hole hides behind veils of dust, gas, and warped spacetime. Now a ...

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.

The second reason is simple: location, location, location! The millisecond pulsar appears to be near Sagittarius A*, the ...

Most of the universe is slipping away from the Milky Way, carried outward as space itself expands. Yet one giant neighbor is bucking the trend, racing straight at us while almost every other major ...

A vast, flat sheet of dark matter may solve the long-standing mystery of why our neighboring galaxy Andromeda is speeding ...

The Milky Way is our home galaxy with a disc of stars that spans more than 100,000 light-years. Though the Milky Way is generally always visible from Earth, certain times of year are better for ...

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 ...

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.
