New research suggests that the heart of the Milky Way may be dominated by a dense clump of dark matter rather than the ...

Astronomers tracked a star in Andromeda as it dimmed and vanished without the usual fiery explosion, offering rare clues to ...

If confirmed, this disappearing act might provide the closest and best observational evidence for the birth of a black hole ...

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

A massive star in the nearby Andromeda galaxy has simply disappeared. Some astronomers believe that it's collapsed in on ...

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.

Webb telescope data confirm a supermassive black hole fleeing its galaxy, carving a 200,000 light-year wake of new stars.

The team discovered the star by analyzing archival data from NASA’s NEOWISE mission. They used a prediction from the 1970s ...

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 ...

A massive star 2.5 million light-years away simply vanished — and astronomers now know why. Instead of exploding in a supernova, it quietly collapsed into a black hole, shedding its outer layers in a ...

Astronomers have spotted the most massive known stellar black hole in the Milky Way galaxy after detecting an unusual wobble in space. The so-called "sleeping giant," named Gaia BH3, has a mass that ...

Astronomers have witnessed a rare cosmic event: a massive star that didn’t explode in a spectacular supernova, but instead ...
