The known black holes that populate the universe fall into two types: those up to a few dozen times the mass of the sun and ...

Astronomers also suspect that a class of objects called intermediate-mass black holes exist in the universe, although evidence for them is so far debatable. No matter their starting size ...

A black hole is a dense object in space where the gravitational pull is so strong that nothing can escape it, not even light. Black holes form when massive stars collapse, with huge black holes ...

A black hole is a region of spacetime where gravity is so intense that nothing, no matter how much energy it has, can escape. Inside the event horizon, gravity supersedes all other forces of nature.

Astronomers found a massive black hole that spent ages in a "quiet" phase when everything around it in the early universe ...

as well as in objects right here on Earth. “We have to think outside of the box because what has been done to find primordial black holes previously hasn’t worked,” Dejan Stojkovic of the ...

Set to be published in the December issue of Physics of the Dark Universe and available online now, the theoretical study posits that a primordial black hole trapped within a large rocky object out in ...

On Sept. 14, 2015 astronomers “heard” two black holes crashing into each other at close to the speed of light. This discovery ...

Black holes are objects with an intense gravitational pull so strong that not even beams of light, the fastest things in the universe, can escape. This makes them impossible to see directly ...
