• A supermassive black hole has been spotted “firing” jets of super-energised plasma at velocities which, at first glance, appear to be moving at an incredible seven times the speed of light.
  • One such blast has hit something — and the enormous flare of its vaporisation has been discovered in a timelapse sequence of images taken by Hubble over the course of two decades.
  • At first glance, it seemed as though one fast knot of plasma shot out at an apparent speed of seven times the speed of light — and slammed into a slower moving ejection in front of it. But the super-energised plasma had not broken Einstein’s universal speed limit: It was an optical illusion caused by the speed it is actually moving — an incredible 98 per cent of the speed of light.
