The newly discovered pair, nicknamed Porphyrion after a rebellious giant in Greek mythology, were spotted in observations from LOFAR, a network of radio wave detectors in the Netherlands.

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.

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.
