Across the sky, more than 100 stellar-mass black holes are hidden within a large cluster of stars. The star cluster is named Palomar 5, and it stretches out over 30,000 light-years. It is located ...

Chandra X-ray Observatory observations of the Perseus galaxy cluster's black hole and M87's jet have been turned into sound ...

A quasar is an exceptionally bright and uncommon supermassive black hole found at the core of a galaxy. NASA researchers have ...

The energetic streams are together 23 million light-years in length—roughly as long as 140 Milky Way galaxies lined end to end Shi En Kim The black hole, if confirmed, is in the star cluster ...

Black holes are points in space that are so dense they create deep gravity sinks. Beyond a certain region, not even light can escape the powerful tug of a black hole's gravity. And anything that ...

instead of one massive black hole, lurking at the heart of the globular cluster NGC 6397. Globular clusters are extremely dense stellar systems, which host stars that are closely packed together.

"Overall, it's not surprising that black holes should be in triples, but what's surprising is that this system held onto the outer star after forming the black hole." ...

The team at MIT and Caltech also discovered that the black hole system is 4bn years old. In a chance discovery, MIT and Caltech scientists have found two objects orbiting a black hole for the ...

Hubble detected the black hole by observing the motion of stars near the cluster's centre, which suggested a massive, unseen object was pulling on them. The stars' motions revealed a consistent ...

By observing a cluster of stars near the hole ... The result will help scientists better understand the physics of black holes. The Very Large Telescope (VLT) in Chile found evidence for ...

The universe is home to many fascinating objects. R Aquarii is a binary star system with a red giant and a white dwarf. Omega ...
