"Our measurements imply that the supermassive black hole mass is 10% of the stellar mass in the galaxies we studied." Using the James Webb Space Telescope (JWST), astronomers have discovered ...

Besides stars, the United States Navy uses quasars as beacons. Quasars are distant galaxies with supermassive black holes, surrounded by ... X-Ray Flashes from a Nearby Supermassive Black Hole ...

"These observations provide a more complete picture of the black hole's environment and its dynamics." It may have been the first black hole imaged by humanity, but the eating habits of the ...

A "missing link" black hole in Omega Centauri is still missing. What appeared to be an intermediate-mass black hole was a cluster of stellar-mass black holes. New research may have delivered bad ...

Supermassive black holes, billions of times heavier than the Sun, sit at the centres of galaxies. Despite their darkness, they emit bright signals when gas spirals around them. Detecting hidden ...

The first black hole that astronomers observed "turning off" just turned back on, releasing jets of hot gas into the cosmos. When you purchase through links on our site, we may earn an affiliate ...

The jets extending from these blazars can extend millions of light-years in length. Black holes are among the most mysterious cosmic objects, much studied but not fully understood. In pursuit of ...

As far as supermassive black holes go, the one at the center of the Milky Way is relatively sedate. But, even in its supposed quiescent state, Sagittarius A* is prone to the occasional belch or ...

Binary black holes could form in merging galaxies Light variations suggest binary black holes in PG 1553+153 Gravitational waves may confirm binary black hole systems ...

An active galactic nucleus (AGN) is a region at the center of a galaxy where a supermassive black hole is actively consuming surrounding material. As this matter spirals toward the black hole, it ...

Instead, the energy from the collapse is primarily carried away by lightweight neutrino particles, with minimal asymmetry. This results in only a small “natal kick” for the newly formed black hole.
