Astronomers have discovered extraordinarily powerful X-ray jets blasting from two supermassive black holes that are so ...

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

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.

Astronomers have seen the largest jets ever found erupting from a black hole. The giant jet system Porphyrion is 23 million light-years long, equal to 140 side-by-side Milky Way galaxies.

NASA's Chandra X-ray Observatory has captured a striking image of a distant quasar from the "cosmic noon," including a giant energy jet "being illuminated by the leftover glow from the Big Bang itself ...

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.

Star explosions called novas are happening twice as often near a gargantuan black hole jet as they are in the rest of the galaxy, and astronomers aren't sure why.

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 times ...

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.

The black hole resides at the heart of a galaxy about 7.5 billion light-years from Earth. A light-year is the distance light travels in a year, 5.9 trillion miles (9.5 trillion km).
