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 ...

During the survey, researchers identified a promising 8.19-millisecond pulsar (MSP) candidate located close to Sagittarius A*, the supermassive black hole at the center of our galaxy.

Scientists scanning the heart of the Milky Way have spotted a tantalizing signal: a possible ultra-fast pulsar spinning every 8.19 milliseconds near Sagittarius A*, the supermassive black hole at our ...

Astronomers suspect the heart of the Milky Way may be hiding a big secret: a rapidly spinning, highly magnetic, neutron ...

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

A fluffy cluster of stars spilling across the sky may have a secret hidden in its heart: a swarm of over 100 stellar-mass black holes. The star cluster in question is called Palomar 5. It's a stellar ...

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.
