Astronomers have been left stunned after spotting a black hole 'burping' out material three years after it devoured a star.
The rare cosmic event took place 665 million light years away, creating a bright display visible from space telescopes on Earth.
A more routine burst of activity had previously been picked up in 2018, when the black hole was seen swallowing up a smaller star and tearing it into small pieces in a Tidal Disruption Event (TDE) named AT2018hyz.
