And for the first time, astronomers have now seen that blaze mysteriously snuffed out, before gradually returning to brightness.

The supermassive black hole is a beast clocking in at 19 million solar masses, powering a galactic nucleus 275 million light-years away, in a galaxy called 1ES 1927+654.
