Messier 88 is an active galaxy with a central supermassive black hole that is gobbling up gas and dust

Debate still swirls around the nature of “little red dots,” black holes glimpsed in the early universe by the James Webb Space Telescope. A controversial new weigh-in may settle the matter

Our galaxy and its nearest large companion, Andromeda, may be headed for a collision on a cosmic scale. What happens then?

The new image shows the galaxy NGC 1266, a transitional object with a clutch of young stars that likely collided with a smaller galaxy 500 million years ago

Subatomic black holes from ancient cosmic history could, in principle, make you have a very bad day. But chances are you’ll never encounter one

A first-of-its-kind observation shows how jets from voracious black holes can shape the growth of galaxies

Long ago, the cosmos might have been a black hole factory—and these primordial objects are even weirder than you think

A new data release more than doubles the number of gravitational-wave candidate events—and reveals unexpected complexities of merging black holes

Despite years of debate and follow-up studies, an odd streak of cosmic light still defies a final explanation. Is it a giant black hole screaming through intergalactic space?

The strange case for prime numbers at the heart of physics

The collision of supermassive black holes shakes the entire cosmos, hard

A “disappearing” star in the Andromeda galaxy is the closest and best candidate for a newborn black hole that astronomers have ever seen
