Intergalactic unions more devastating than we thought

Scientists from MIPT, the University of Oxford, and the Russian Academy of Sciences have estimated the number of stars disrupted by solitary supermassive black holes in galactic centers that formed via mergers of galaxies ...

Spinning black hole swallowing star explains superluminous event

In 2015, the All Sky Automated Survey for SuperNovae (ASAS-SN) detected an event, named ASASSN-15lh, that was recorded as the brightest supernova ever—and categorised as a superluminous supernova, the explosion of an extremely ...

Studies find echoes of black holes eating stars

Supermassive black holes, with their immense gravitational pull, are notoriously good at clearing out their immediate surroundings by eating nearby objects. When a star passes within a certain distance of a black hole, the ...

Dormant black hole eats star, becomes X-ray flashlight

Roughly 90 percent of the biggest black holes in the known universe are dormant, meaning that they are not actively devouring matter and, consequently, not giving off any light or other radiation. But sometimes a star wanders ...

Astronomers catch a black hole shredding a star to pieces

When a star comes too close to a black hole, the intense gravity of the black hole results in tidal forces that can rip the star apart. In these events, called tidal disruptions, some of the stellar debris is flung outward ...
