A supermassive black hole was observed belching up a star it gobbled up three years earlier — leaving astronomers puzzled by the delayed intergalactic indigestion. “This caught us completely ...

Astronomers at the University of Hawaii uncovered black hole events so packed with energy, they were the biggest explosions seen since the Big Bang.

radio and other waves for up to a few weeks or months while they occur. When they happen, some of the leftover gas and dust from a destroyed star is flung away from the black hole. The rest then ...

The black hole would create different convection patterns deep in the star’s interior, which could potentially be picked up through a technique called asteroseismology.

Tidal disruption events occur when a black hole gobbles up a star, sending out a flash of electromagnetic radiation detectable by telescopes. In 2018, scientists discovered that one such TDE ...

To detect the gravitational wave background, astronomers studied fast-spinning stars called millisecond ... waves originating from smaller black holes that are up to 10 times as massive as the ...

While solitary black holes should be common, they are hard to find. The one in Sagittarius revealed itself when it passed in front of a dim background star, magnifying the star’s light and ...

Years after ripping stars to shreds, 24 black holes suddenly flared up with radio waves in inexplicable 'burping' bouts. Half of all star-killing black holes may experience the same. When you ...
