In the first few hundred million years after the Big Bang, something strange happened: many massive black holes already ...

Researchers have spent the past few years watching a black hole re-awaken roughly 300 million light-years away from Earth.

A supermassive black hole dormant for decades has just awakened in a distant galaxy. This sudden activation provides a unique ...

Active black holes have a pancake-shaped structure around them called an accretion disk, which contains hot, electrically charged gas. The plasma that makes up the accretion disk comes from farther ...

The quasi-periodic eruptions of X-rays from a black hole 300 million light-years away are unlike any researchers have ever ...

Scientists have discovered key conditions needed for a stellar black hole to create plasma jets. Their findings show that when superheated gas material experiences a rapid shrinkage towards the black ...

The basic idea is that you send a beam of light around a pair of black holes spinning around each other prior to a merger, or ...

A supermassive black hole that scientists have nicknamed "Ansky" is now awake after a long dormant period, emitting powerful ...

In 2018 astronomers at MIT and elsewhere observed previously unseen behavior from a black hole known as 1ES 1927+654, which ...

Something unexpected has come to life in the great darkness of space. In a galaxy 300 million light-years away from Earth, a ...

2024 — Researchers conducted innovative simulations of spinning black holes grounded in general relativity, which clarified that the ultraluminous accretion disk (i.e., gaseous spiral ...
