The largest known black hole jets, 23 million light years across, have been discovered in the distant universe. This pair of particle beams launched by a supermassive black hole is over a hundred times larger than our galaxy,

Astronomers observed a close pair of black holes dancing around one another using the Hubble Space Telescope and Chandra X-ray Observatory.
