A black hole’s bizarre "heartbeat" is forcing astronomers to reconsider how these cosmic heavyweights behave. Observations of IGR J17091-3624 — a black hole in a binary system roughly 28,000 ...

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 ...

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 ...

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

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 ...

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 ...
