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

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

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 ...

A string of small gas clouds near the Milky Way’s central black hole has puzzled astronomers for years. Now, new observations ...

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) ...

Supermassive black holes are among the most enigmatic objects in the universe. They typically weigh millions or even billions ...

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 ...

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

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

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 ...

While scientists know supermassive black holes collide, these events have remained invisible to telescopes. RIT researchers have now identified a specific spike in light that occurs at the moment of ...
