For decades, scientists have theorized that the Milky Way Galaxy’s supermassive black hole, known as Sagittarius A* (Sgr A*), ...

A massive filament of gas and dust, designated X7, has been elongated during its long approach to the Milky Way galaxy's supermassive black hole Sagittarius A*. See W.M. Keck Observatory imagery of X7 ...

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.

In 2014, a NASA telescope observed that the infrared light emitted by a massive star in the Andromeda galaxy gradually grew brighter. The star glowed more intensely with infrared light for around ...

There's no denying that something massive lurks at the heart of the Milky Way galaxy, but a new study asks whether a ...

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

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.

If the pulsar is confirmed, it could enable more precise measurements of the space-time around the galaxy’s central supermassive black hole ...

WASHINGTON, Feb 12 (Reuters) - The formation of a black hole can be quite a violent event, with a massive dying star blowing up and some of its remnants collapsing to form an exceptionally dense ...
