Rochester Institute of Technology scientists have developed new simulations of black holes with widely varying masses merging that could help power the next generation of gravitational wave detectors.

Some of the brightest beacons in the universe share one hidden engine: matter falling into a black hole. As gas whirls inward, it heats up and shines. In some cases, it also blasts narrow beams of ...

Stellar winds blowing away from a nearby binary star probably form the gas clouds.

A supermassive black hole feeding on a star is accompanied by intense radiation that can briefly outshine the galaxy where the event is taking place.

A new simulation could help solve one of astronomy’s longstanding mysteries—how supermassive black holes formed so rapidly—along with a new one: What are the James Webb Space Telescope’s (JWST) ...

Black holes, regions of spacetime in which gravity is so strong that nothing can escape, are intriguing and extensively studied cosmological phenomena. Einstein's general theory of relativity predicts ...

Near the black hole (shown in the center), an accretion flow forms a dense, thin thermal disk embedded within a magnetically dominated envelope that helps stabilize the system. The flow is ...

The jets do not move in a straight, obedient line. Around Cygnus X-1, a black hole and a massive supergiant star circle each ...

Scientists are getting a clearer look at what happens when a black hole tears a star apart and why each cosmic flare looks ...

In 2014, a strange cloudy object called G2 made a close approach to Sagittarius A*, (Sag A*) the supermassive black hole at the heart of the Milky Way Galaxy. Astronomers were pretty excited, partly ...
