Shifting Gears - Stellar Propulsion Primer - Part 02

Sambruna's team, comprising researchers at Goddard and the Merate Observatory, Merate, Italy, studied a type of quasar called a blazar. Blazars are quasars with their particle jets aimed in our direction, as if we are staring down the barrel of the gun. The team studied two blazars, called 0212+735 and PKS 0537-286, both over 10 billion light years away.

"The jet contains about the same mass as Jupiter, which means the central black hole is like a cannon firing a massive pulverized planet at near light speed clear out of the galaxy," said Tavecchio. "That's an enormous amount of energy leaving the black hole system, and this is happening throughout the universe."
