In a major leap forward, scientists, using the Event Horizon Telescope (EHT), have captured the sharpest images yet of distant galactic centers. Using light at a frequency of 345 GHz, they’ve peered ...

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

A black hole that was eaten by a star seems to have gotten revenge by consuming the star from the inside, producing a gamma-ray burst spotted about 9 billion light-years from Earth. The burst, called ...

Researchers believe the 'ultramassive' black hole is big enough to be the largest of its kind ever detected. Black holes are regions of space where the pull of gravity is so intense that even light ...

Scientists say they detected the largest-ever merger of two black holes, forming one that is 225 times the mass of the sun, adding that the new discovery "pushes the limits of" how astronomers ...

Astronomers have discovered the oldest and most distant black hole — a behemoth that likely formed at the dawn of the universe, more than 13 billion years ago. The black hole lies at the center of a ...
