"This challenges our understanding of black hole and galaxy formation in the early universe."

Albert Einstein's theory of gravity, general relativity, may not be the best recipe to describe black holes.

Scientists may have solved the mystery of an "impossible" merger between two black holes so massive and fast-spinning that they shouldn't even exist, according to current theory.

"The James Webb Space Telescope has opened a new frontier in extragalactic astrophysics, revealing objects we didn't even suspect existed, and we're only at the beginning of this adventure."

Astronomers have detected the most distant and biggest black hole flare ever seen, the result of a black hole ripping apart and devouring a star 30 times as massive as the sun.

An unexpected monster black hole was found hiding inside one of the Milky Way’s tiniest neighbors, rewriting what scientists thought they knew about how small galaxies hold themselves together.

Gravitational wave detectors on Earth have heard the "cry" of two newborn black holes with some unusual and remarkable properties.

The so-called tidal disruption event also produced two puzzling delayed outbursts.

Identifying the gravitational waves from black holes binaries could also make it clearer to detect primordial gravitational waves that date back to inflation at the moment of the Big Bang.

After decades of searching, astronomers have imaged two supermassive black holes in orbit around each other at the heart of quasar OJ287.
