Astronomers have spotted the biggest pair of black hole jets ever seen — at 23 million light-years in length, they are as long as 140 Milky Way galaxies laid end to end.
The enormous jet pair, nicknamed Porphyrion after a giant in Greek mythology, are gigantic beams of ionized matter that erupted from a black hole at close to light speed. Their origin is a massive black hole 7.5 billion light-years away from Earth, which they burst from with the power of trillions of stars.
