Astronomers have discovered extraordinarily powerful X-ray jets blasting from two supermassive black holes that are so ancient that the jets shine in the afterglow of the Big Bang.

Astronomers have spotted a massive pair of jets releasing material from a distant black hole. The jets are so large they span about 140 Milky Way galaxies in length.

Using the XMM-Newton telescope, astronomers have witnessed high-speed "burps" erupting from a distant overfeeding supermassive black hole.

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.

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.

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 ...

A new study reveals that one such pair of jets, belonging to a black hole some 7.5 billion light-years away, stretches some 23 million light-years—the equivalent of placing 140 Milky Ways in a ...
