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 ...
A recent cosmic discovery reveals a black hole tearing apart one star and hurling its remains at another. This event links ...
Massive stars about eight times more massive than the sun explode as supernovae at the end of their lives. The explosions, ...
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 ...

But some, it turns out, may be born in a gentler fashion. Researchers have identified a black hole that appears to have come into being through the collapse of the core of a large star in its ...
