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 ...

Primordial black holes may be exploding throughout the universe. If we can catch them in the act, it could pave the way to ...

At the heart of our Milky Way galaxy lurks a supermassive black hole about four million times the mass of the sun, called ...

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.

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.

Beyond a certain region, not even light can escape the powerful tug of a black hole's gravity. And anything that ventures too close—be it star, planet, or spacecraft—will be stretched and ...
