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 ...

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.

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 ...

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

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 ...

Black holes are famous for gorging on infalling matter ... this bubble in the hot X-ray plasma in the centre of this galaxy cluster, and they said, 'Well, this can't be from one of these energetic ...

Supermassive black holes exist at the center of most galaxies, and modern telescopes continue to observe them at surprisingly early times in the universe's evolution. It's difficult to understand ...

Black hole light echoes are an extreme form of gravitational lensing. To measure the masses and spins of black holes, scientists want to follow clues left behind by light that takes a round-a-bout ...

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 ...

Astronomers suggest the vermilion black hole was the result of an expanding ... of distant galaxies in the central core of Pandora's Cluster, also known as Abell 2744, some 4 billion light-years ...
