When a black hole and a neutron star finally meet, the result is cosmic carnage—and now, thanks to Caltech’s latest supercomputer simulations, we’re getting a front-row seat to the whole terrifying ...

Astronomers have identified what could be a new supermassive black hole, and with an estimated mass 36 billion times that of the sun, it has about 10,000 times the mass of the black hole at the center ...

They’re the boogeymen of science fiction, a paradox of science and quite possibly a key to understanding the universe. Scientists have been scrambling to understand the mysterious forces of black ...

When black holes emerge out of hiding to feast on their prey and some type of matter is sucked into their celestial maw, they begin to glow brightly. The events, dubbed “extreme nuclear transients,” ...

Talk about epic. A collision of two black holes is so extreme that it’s challenging physics theories of how large black holes form and merge. The two black holes had masses bigger than any before ...

Scientists detected the merger of two extremely massive black holes. This merger created the most massive black hole ever observed through gravitational waves. The black holes' size and rapid spin ...

A record-breaking black hole smash-up just expanded our view of the universe’s most extreme inhabitants. Is our cosmos just a membrane on the edge of a far stranger reality? These black holes’ masses ...

Images taken of the Universe's most photogenic black hole over time reveal strange and exciting changes in its magnetic field. Using observations obtained using the Event Horizon Telescope in 2017, ...

One of the first black holes ever imaged is even stranger than we thought, new images of its dramatically changing environment reveal. The object, known as M87*, has experienced unexpected changes in ...

In a recent piece for my column The Universe, I wrote about the biggest black holes in the cosmos. These can tip the scales at many billions of times the sun’s mass, outweighing even entire galaxies.
