"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 ...

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 ...

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 ...

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 ...

Black holes that have been obscured by clouds of dust still emit infrared light, enabling astronomers to spot them for the very first time When you purchase through links on our site, we may earn ...

Researchers in South Korea are developing a constellation of satellites that could reveal what goes on in the vicinity of supermassive black holes like never before. The constellation, dubbed ...

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 ...

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 ...

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 ...

NASA's James Webb Space Telescope found evidence that supermassive black holes suppress star formation in maturing galaxies. The team used the James Webb Space Telescope's (JWST) Near Infrared ...

Scientists had already been intrigued by this cosmic giant after a remarkable event in 2018, when its corona - made up of swirling hot plasma - suddenly vanished before reappearing months later. "We ...

Simulation of two colliding supermassive black holes emitting gravitational waves that could be detected with this novel method. Credit: NASA’s Goddard Space Flight Center/Scott Noble; simulation data ...
