The black hole, spotted 5 billion light-years away in the Cosmic Horseshoe, could be the most massive ever found.

An ambitious plan to test extreme physics close to a black hole would involve a space probe weighing only a few grams, travelling at a third of the speed of light ...

Alas, we do not live in Star Trek; the speed of light, as far as we can tell, is an insurmountable limit. This means that ...

Over the past decade, the LIGO-Virgo-KAGRA (LVK) network has detected hundreds of black hole mergers, but none quiet as large as GW231123. At 225 solar masses, the black hole resulting from the ...

The supermassive black hole at the center of our Milky Way galaxy, by contrast, has a mass of roughly 4 million solar masses, and it has an event horizon with a radius of 7.3 million miles or 17 ...

When a star strays too close to a supermassive black hole, extreme gravitational forces ravage it, shredding and stretching it into spaghetti. The term for this gruesome process is actually ...

It was the EHT that took a picture of the black hole in a galaxy known as M87, which is some 54 million light years from our Milky Way. That image, released in April 2019, was the first-ever photo ...

A zoom into M87’s monster black hole, thanks to Hubble. Their answer leaned on another recurring natural pattern – chaos.

The black hole in question, with the uninspiring name 1A 0620-00, is the closest to our planet, but still lies about 3,300 light years away. As a result, the Hawking audio tribute will take ...

Here’s what you’ll learn when you read this story: Over the past decade, the LIGO-Virgo-KAGRA (LVK) network has detected hundreds of black hole mergers, but none quiet as large as GW231123. At ...
