The newly discovered black hole-driven jets extend over 7 megaparsecs or 23 million light-years.

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 the diameter of our vast Milky Way galaxy.

Scientists have discovered the longest pair of jets streaming from a black hole in a distant galaxy. The jets shooting hot plasma are the largest ever spotted – about as long as 140 Milky Way galaxies lined up end-to-end.

Spanning 23 million light years, or 220 Milky Way galaxies, a set of giant, newly discovered black hole jets known as Porphyrion may change our understanding of black holes and the structure of the un

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. That is equivalent to lining up 140 Milky Way galaxies back-to-back.
