Astronomers found the biggest pair of black hole jets ever observed, stretching 23 million light years. and named this system ...

The two plasma fountains, spanning 23 million light-years, could shape cosmic structures far beyond their home galaxy.

Astronomers have found a true colossus of a jet in the night sky, over 100 times larger than our galaxy. It’s almost ...

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.

Porphyrion, named after a giant from Greek mythology, is a cosmic megastructure that amassed when the universe was only 6.3 billion years old, and spans roughly the same distance of 140 Milky Ways.

The study describing the jet megastructure, dubbed Porphyrion after a mythological Greek giant, is published today in Nature. “We present evidence that supermassive black holes do not only hold ...

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.

Before these jets—nicknamed Porphyrion after a giant in ancient Greek myth—were discovered, it was thought that supermassive black hole jets couldn't get larger than 5 megaparsecs, or about 16 ...

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.

The gigantic jets have been given a suitably mythic name, with the team that discovered the megastructure dubbing them "Porphyrion" in reference to the giant offspring of Gaia in Greek mythology.
