Supermassive black hole caught 'burping' twice after colliding with nearby galaxy

Supermassive black hole caught 'burping' twice after colliding with nearby galaxy
From CBC - January 12, 2018

Using two telescopes, astronomers have found a black hole at the centre of a galaxy 800 million light years awaythat has spewed material into space not once, but twice.

Most galaxies have a supermassive black holeat their centres, which consumes anything that gets too close. And while we tend to think of nothing escaping a black hole's fierce grasp, when they devour material, some of it is ejected into space in the form of high-energy particles.

In order to see the two events, astronomers used data from ground-based telescopes as well as the Hubble Space Telescope and the Chandra X-Ray Observatory.

Optical data from Hubble and the other telescopes found that the black holewhich is millions or perhaps billions of times more massive than our sun at the centre of the galaxydesignatedSDSSJ1354+1327 had ejected material twice, 100,000 years apart.
