Views of a massive galaxy cluster Abell 2256 have been captured by NASA’s Chandra X-ray Observatory, ESA’s XMM-Newton and ...

It's as if the black hole basically hurled it out of the galaxy. Sponsor Message Han and his colleagues recently studied 21 of these hypervelocity stars at the fringes of the Milky Way.

Researchers used an AI model to create a new image of the black hole at the center of the Milky Way, with some concern from experts.

Researchers have found that the supermassive black hole in the center of our Milky Way galaxy, known as Sagittarius A*, is spinning so rapidly that it is altering the fabric of space-time around it.

The supermassive black hole at the center of our galaxy, Sagittarius A*, is spinning rapidly and altering space-time around it, a new study has found. Space-time is the four-dimensional continuum ...

There are gargantuan 'supermassive' black holes like the one at our galaxy's center, 26,000 light years from Earth, which is four million times the sun's mass.

The monster black hole in galaxy cluster Abell 85 is roughly the size of our solar system, but packs the mass of 40 billion suns. Skip to content Introducing the all-new Astronomy.com Forum!

The type of black hole that’s sitting in the center of a galaxy is different. This is a supermassive black hole, or SMBH, and — as its name implies — it’s much heftier.

But “if a black hole leaves a galaxy, it doesn’t leave by itself,” van Dokkum says. Some of the stars and gas that were gravitationally bound to the black hole leave with it.
