The Hubble Telescope and Chandra X-ray Observatory saw an enigmatic intermediate-mass black hole lighting up in X-rays, potentially revealing a way of finding more of them in the future.

A black hole tore into the same star twice, revealing that some stars may survive tidal disruption events and repeatedly flare.

Now, in a preprint uploaded to the arXiv server, LVK scientists have provided evidence that there’s a new heavyweight champion—a merger that produced a new 255-solar-mass black hole.

It took less than a second for the space observatory hidden in Louisiana woods to detect a black hole that is that is approximately 225 times the mass of the sun.

How was the collision of two black holes detected? The two black holes were spinning at about 400,000 times faster than the Earth’s rotation when they collided, billions of years ago.

Gravitational-wave detectors have captured their biggest spectacle yet: two gargantuan, rapidly spinning black holes likely forged by earlier smash-ups fused into a 225-solar-mass titan, GW231123 ...

LIGO has detected an increasing number of black hole mergers with each upgrade, so it will probably identify more cosmic record-breakers going forward.

The powerful merger, designated GW231123, produced an extremely large black hole about 225 times the mass of our Sun.

What's at the center of a black hole? Scientists have a sobering answer. First, the good news: Black holes aren’t out to get us. But they do hold unfathomable mysteries.

When black holes need a place to crash, they prefer a nice, bright quasar.

A new paper claims astronomers discovered an ultramassive black hole heavier than any other black hole we've ever measured.
