When two orbiting supermassive black holes get close to each other, the results can be pretty twisted. A new NASA visualization shows how the irresistible pull of extreme gravity bends … Read more
In recent years, cosmologists have been faced with a crisis: The universe is expanding, but no one can agree on how fast it’s moving away from us. That’s because different … Read more
Black holes, those gravitational monsters so named because no light can escape their clutches, are by far the most mysterious objects in the universe. But a new theory proposes that … Read more
First-of-their-kind images of the magnetic field around a black hole may explain how the black hole shoots out a jet of energy and matter more than 5,000 light-years into space. … Read more
In 1974, Stephen Hawking theorized that the universe’s darkest gravitational behemoths, black holes, were not the pitch-black star swallowers astronomers imagined, but they spontaneously emitted light — a phenomenon now … Read more
Aliens could be sucking power from black holes — and that could be how we’d spot the extraterrestrials, scientists say. This energy-harvesting technology could leave traces just outside a spinning … Read more
Physicists are currently in a golden age of new knowledge about black holes. Since 2015, researchers have been able to get signals directly from merging black holes using the Laser … Read more
The universe might be full of tiny, ancient black holes. And researchers might be able to prove it. These mini black holes from the beginning of time, or primordial black … Read more
The cosmos may be studded with black holes so tiny they could slip in between atoms, a wild new theory suggests. And we could be making these teensy singularities all … Read more
Black holes can get big … really big. But just how big? It’s possible they could top out at over a trillion times more massive than the sun. That’s 10 … Read more
