Astronomers found the biggest pair of black hole jets ever observed, stretching 23 million light years. and named this system Porphyrion.

Astronomers have made an astonishing discovery with a pair of black hole jets stretching 23 million light-years across the cosmos. These colossal jets, nicknamed Porphyrion, are the largest ever recorded.

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, the Milky Way.

Strange Universe Like a parasite sucking the life force out of its host, an international group of scientists have determined that a supermassive black hole is starving a galaxy of essential materials to make new stars.

The energetic streams are together 23 million light-years in length—roughly as long as 140 Milky Way galaxies lined end to end

A fluffy cluster of stars spilling across the sky may have a secret hidden in its heart: a swarm of over 100 stellar-mass black holes. The star cluster in question is called Palomar 5. It's a stellar stream that stretches out across 30,

There's only one thing it could be: a black hole, one with a petite size that's smack bang in the middle of a mysterious void in the data known as the lower mass gap. Named G3425, it might have a lot to teach us about tiny black holes according to an analysis.
