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.

Nicknamed Porphyrion after a mythological Greek giant, these jets span roughly 7 megaparsecs, or 23 million light- years. That is equivalent to lining up 140 Milky Way galaxies back-to-back.

Astronomers have named the jets Porphyrion, after a giant from Greek mythology. They were spotted far enough away that the universe was only 6.3 billion years old – less than half its present age.

Porphyrion was discovered by astronomers using the International LOFAR Telescope, a network of radio sensors centered in the Netherlands, and stretching from Sweden to Bulgaria, ...

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.

Nicknamed Porphyrion after a mythological Greek giant, these jets span roughly 7 megaparsecs, or 23 million light-years. That is equivalent to lining up 140 Milky Way galaxies back-to-back.

Porphyrion’s prodigious size — it outstretches the previous record holder by about 7 million light-years — hints that its influence could outstrip the bounds of mere galaxies.

Astronomers have spied a monster radio jet in the distant universe that’s twice the width of the Milky Way galaxy.The ancient object formed when the universe was less than 10% of its current age ...

Porphyrion is an extremely large giant at a distance of about 7.5 billion light years,” Gloudemans said. “Our newly discovered jet doesn’t come close to the 23 million light year size of ...
