But in the past two decades, new types of black holes have been seen and astronomers are beginning to understand how they ...

A physics conference has received a report of the gravitational wave from the heaviest pair of black holes we’ve so far ...

Theories continue to fly about the Monsterverse, and an entertaining one indicates that the legendary villain SpaceGodzilla ...

A puzzling gravitational wave was detected, and astronomers have determined that it comes from a record-breaking black hole ...

Scientists have witnessed evidence of a collision between black holes so huge that it defies their understanding of physics.

Astronomers at the University of Hawaii uncovered black hole events so packed with energy, they were the biggest explosions ...

Some stars may transform into black holes without exploding into supernovae. Now, astronomers have finally spotted it as it happened.

Two international teams zoned in on a potential answer to a decades-long mystery surrounding ephemeral cosmic X-rays.

The universe is a chaotic place filled with exploding stars, material falling into black holes, and rogue planets wandering off on their own. All that chaos makes astronomers suspicious when they ...

Astronomers believe they've uncovered the source behind mysterious cosmic signals known as fast x-ray transients (FXTs) — and ...

Scientists have discovered the most powerful blasts of energy in the known universe. Dubbed extreme nuclear transients, or ENTs, the cosmic explosions are unprecedented in their intensity.

Unlike a supernova, which cools over time, this light stayed hot, which is consistent with matter falling into a black hole. But why exactly is this roaming black hole so far from home? The answer ...
