Black Holes

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

Researchers have found what might be a little red dot transitioning into its final state, where x-rays burst through its gas cocoon. Others argue the object is nothing special

Radio images captured this “cosmic volcano” being reborn at the heart of the galaxy J1007+3540

Puzzling red spots in images from the James Webb Space Telescope are probably young supermassive black holes obscured by dense cocoons of gas

A wobbling jet from a giant, voracious black hole is suppressing star formation in a distant galaxy—and astronomers have never seen anything quite like it before
