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 ...

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 ...

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.

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 ...

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.

To date, LOFAR has detected more than 10,000 black hole megajets. To study Porphyrion in further detail, the team roped in a trio of other Earth-based telescopes.
