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

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.

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

Caltech’s Katie Bouman explains how the Event Horizon Telescope Collaboration captured the first imager of the Sagittarius A* Supermassive black hole at the core of the Milky Way galaxy - Milky Way vs ...

XRISM measurements map gas velocities in the Perseus and Virgo clusters, separating black hole-driven turbulence from merger-driven motion using high-resolution X-ray spectroscopy.

Woven through the universe are forces, often unseen, that dictate its grand design. For example, at the very heart of nearly every galaxy, we find a supermassive black hole. This isn't just some ...
