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.

For the first time, scientists have the calculations and simulations to explain mysterious flashes from the galaxy OJ 287.

The experiment at CERN produced pairs of electron and positron beams, propagating into an ambient plasma. The international team of researchers found that the beams were narrow and nearly parallel, ...

Astronomers have confirmed the earliest, most distant black hole yet – and it's surprisingly monstrous for its time. Residing in a galaxy called CAPERS-LRD-z9, it was already approximately 300 million ...

For the first time, scientists have the calculations and simulations to explain mysterious flashes from the galaxy OJ 287.

Astronomers have known that black holes exist for some time. Ever since Einstein’s general theory of relatively, they have understood the concept of black holes, and more recently, there has even been ...

Some black holes, bound by gravity, rotate around each other, as shown in this simulated image. Simulating eXtreme Spacetimes Lensing (SXS), CC BY-SA Black holes are regions of space where gravity is ...

One of the most notable aspects about our planet—if observed from the outside—is that it spins. Earth’s spin defines our days, setting the fundamental rhythm of life on our world. The moon spins, too.

When space telescopes blazed with high-energy radiation for hours earlier this year, astronomers suspected that they were witnessing something special. The cosmic flash GRB 250702B was no ...

Astronomers have discovered the longest gamma-ray burst ever recorded, revealing that a black hole literally consumed a star ...

An undiscovered population of ancient black holes may be lurking throughout the universe. These bottomless cosmic pits would have a lot in common with more familiar black holes; in some cases, the two ...
