Astronomers have spotted a massive pair of jets releasing material from a distant black hole. The jets are so large they span about 140 Milky Way galaxies in length.

A citizen science effort to identify other large black hole jets has turned up more than 10,000 that span roughly 3 million light-years or more, though none as large as Porphyrion. “Those large ...

Astronomers have seen the largest jets ever found erupting from a black hole. The giant jet system Porphyrion is 23 million light-years long, equal to 140 side-by-side Milky Way galaxies.

Before Porphyrion was spotted, the largest confirmed black hole jet system was Alcyoneus. The same team found Alcyoneus, also named for a mythical Greek giant, in 2022, and this jet system equals ...

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.

But in the past two decades, new types of black holes have been seen and astronomers are beginning to understand how they ...

Astronomers have discovered a black hole emitting energy in jets longer than the width of 140 Milky Way galaxies. An artist’s concept of Porphyrion, a jet of material 23 million light-years long ...
