These are rare occurrences—scientists estimate that the giant black hole at the center of our Milky Way galaxy gobbles a star ...

These explosions, called extreme nuclear transients, shine for longer than typical supernovas and get 30 to 1,000 times as bright.

Traditionally thought to go silent after a brief flare of activity, some black holes are now being observed emitting new ...

ENTs occur when stars that are at least three times as massive as the Sun pass so close to a supermassive black hole that its colossal gravity shreds them to pieces. The resulting string of matter ...

Supermassive black holes usually lurk unseen, but when an unlucky star drifts too close they ignite titanic outbursts ...

Black holes are invisible, yet they are among the brightest things in the universe. If a star wanders too close to a black hole, it gets torn apart in a fireworks show called a tidal disruption ...

A new analysis of BL Lacertae by NASA’s Imaging X-ray Polarimetry Explorer sheds light on the emission mechanisms of active ...

The smooth and long-lived flares of ENTs indicated a distinct physical process—the gradual accretion of a disrupted star by a supermassive black hole.
