Researchers have discovered the largest black hole plasma jets ever in a galaxy almost 7 billion light years away from Earth.

Astronomers have spotted the biggest pair of black hole jets ever seen, spanning 23 million light-years in total length. That's equivalent to lining up 140 Milky Way galaxies back to back.

Scientists have discovered the longest pair of jets streaming from a black hole in a distant galaxy. Black holes eat most space debris that falls their way.

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.

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.
