In 2023, astronomers detected a huge collision. Two unprecedentedly massive black holes had crashed an estimated 7 billion light-years away. The enormous masses and extreme spins of the black holes ...

The sharpest black hole collision ever detected just gave Einstein another win—and raised hopes that the next one might rewrite gravity.

Scientists have named two systems of colliding supermassive black holes after Lord of the Rings locations, Gondor and Rohan.

Back in 1971, the late physicist Stephen Hawking made an intriguing prediction: The total surface area of a black hole cannot decrease, only increase or remain stable. So if two black holes combine, ...

In the fall of 2024, two separate pairs of stellar mass black holes, hundreds of millions of light-years away, spiraled into each other and merged in collisions of unimaginable violence. But these ...

Scientists pursuing supermassive black holes suspect that these giants merge somewhere in the universe roughly once a year, but they don’t know how to find them. They think the evidence is hidden in ...

In this handout photo provided by the National Science Foundation, the Event Horizon Telescope captures a black hole at the center of galaxy M87 in an image released on April 10, 2019. (Photo by ...

Scientists have named newly detected merging supermassive black holes after ’Lord of the Rings’ locations, using gravitational wave data and quasar observations to map their mergers.

A comprehensive set of simulations by Flatiron Institute astrophysicists and their colleagues revealed that magnetic fields are responsible for creating black holes with masses in a range previously ...
