Scientists have found the biggest pair of black hole jets ever seen. Such jets are vast blasts of radiation and particles that erupt out of supermassive black holes. Milky Way jets are the largest galaxy-made structures in the universe.

Astronomers have found the largest black hole jets ever recorded, spanning 23 million light-years and potentially influencing the formation of galaxies across the cosmic web.

In other words, one black hole is continuously erupting energy and plasma into space across a distance more than 140 times longer than our whole galaxy, and it’s carrying the power of trillions of stars. Oei and his colleagues nicknamed the pair Porphyrion. “The Milky Way would be a little dot in those two giant eruptions,” says Oei in a statement.
