In a galaxy 7.5 billion light-years away, a supermassive black hole shoots out streams of magnetized plasma that span 140 Milky Ways in length. This mind-boggling structure—nicknamed Porphyrion, after ...

Massive stars about eight times more massive than the sun explode as supernovae at the end of their lives. The explosions, ...

A recent cosmic discovery reveals a black hole tearing apart one star and hurling its remains at another. This event links ...

A fresh analysis of decades-old X-ray black hole jet data has revealed bright, lumpy features with mysterious speed changes.

Astronomers have found a black hole in the Cygnus constellation formed without a supernova. This unique system includes a black hole and two stars. The black hole, feeding off a nearby red giant ...

It depicts a black hole as a maelstrom in spacetime, characterized by two horizons: an outer one, beyond which nothing can escape its gravitational pull, and an inner one that encloses a ring ...

WASHINGTON, Nov 5 (Reuters) - At the heart of our Milky Way galaxy lurks a supermassive black hole about four million times the mass of the sun, called Sagittarius A*. In fact, these objects ...

Astronomers have discovered a lightweight black hole that’s a bit of a cosmic conundrum. Hypothetically, black hole masses can range all the way from far less than a paperclip to at least tens ...

However, the discovery of the first-ever triple black hole system, V404 Cygni, complicates that picture. This black hole is orbited by a very close star (which orbits every 6.5 days) and a star ...
