Sagittarius A*, our galaxy's supermassive black hole, is constantly producing strange eruptions. Astronomers are using the ...

The flares are common in supermassive black holes and have been seen before, says Farhad Yusef-Zadeh, a professor of physics and astronomy at Northwestern University who led the study.

But in the past two decades, new types of black holes have been seen and astronomers are beginning to understand how they ...

“ENTs are different beasts,” study lead author and astronomer Jason Hinkle explained in an accompanying statement. “Not only are ENTs far brighter than normal tidal disruption events, but they remain ...

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 ...

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

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

New research is shedding light on what researchers call "lite" intermediate-mass black holes, which are smaller, but still ...

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

The scientists who precisely measure the position of Earth are in a bit of trouble. Their measurements are essential for the ...

Long theorized but never observed, the first known “planet with a death wish” is described by Ilin and her colleagues in a ...
