Black Holes

The globular cluster NGC 6397, a conglomeration of stars about 7,800 light-years from Earth, likely harbors a clump of small black holes at its heart, a new study reports.

The upcoming documentary "Black Holes: The Edge of All We Know" explores the many meanings of black holes and the Event Horizon Telescope's pioneering photo. See a trailer for the film here.

In 2018, one of the brightest X-ray lights in the sky went dark, and scientists still aren't sure why.

The universe may be filled with "mirror" particles — and these otherwise-undetectable particles could be shrinking the densest stars in the universe, turning them into black holes.

Not all black holes are perfectly sleek and simple, a new study suggests.

New research proposes that the first black holes came from clumps of gravitinos, exotic, hypothetical particles that managed to survive the first chaotic years of the Big Bang.

A massive jet launched from our galaxy's supermassive black hole may have destroyed any red giant stars that wandered into its path, a new study suggests.

The big galaxy at the core of the cluster Abell 2261 should harbor a supermassive black hole that weighs as much as 3 billion to 100 billion suns. But astronomers can't find it.
