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.

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.

The black hole resides at the heart of a galaxy about 7.5 billion light-years from Earth. A light-year is the distance light travels in a year, 5.9 trillion miles (9.5 trillion km).

The Porphyrion jets, which come from a supermassive black hole about 7.5 billion light-years from Earth, were found thanks to radio images from the International LOFAR Telescope, which revealed ...

Named Porphyrion (another one of those Greek giants), these jets originate from a black hole roughly 7.5 billion light-years from Earth. And they pack quite the punch, delivering a power output ...

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.

Interestingly, Porphyrion’s black hole was in what’s called a radiative-mode state, which is more common in the distant universe. This was unexpected, as radiative-mode black holes weren’t thought to ...

The jets, which Hardcastle and his colleagues have named Porphyrion, come from a black hole in a distant galaxy, some 7.5 billion light years from Earth.

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 ...

Two mighty beams of energy have been detected shooting in opposite directions from a supermassive black hole inside a distant galaxy - the largest such jets ever spotted, extending about 140 times ...
