More strikingly, however, this work showed that Porphyrion’s black hole is also radiating strongly, making its total energy ...

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 ...

Before Porphyrion was spotted, the largest confirmed black hole jet system was Alcyoneus. The same team found Alcyoneus, also ...

Black hole light echoes are an extreme form of gravitational lensing. To measure the masses and spins of black holes, ...

An artist's illustration of the longest black hole jet system ever observed. Nicknamed Porphyrion after a mythological Greek giant, these jets span roughly 7 megaparsecs, or 23 million light-years.

Scientists using observations from NASA's Neil Gehrels Swift Observatory have discovered, for the first time, the signal from a pair of monster black holes disrupting a cloud of gas in the center of a ...
