In April 2019, scientists unveiled an astonishing portrait that used the dimensions of our entire planet as a massive telescope to peer deep into space. The subject was M87*—the first black hole ever to be directly imaged—which occupies the center of a galaxy located 55 million light years away.

The surreal picture, taken by the Event Horizon Telescope (EHT), was a major scientific breakthrough that attracted enthusiastic public interest. Now, scientists have demonstrated that this black hole wobbles in space and glitters in brightness over time. These dynamics could lead to new insights about this particular black hole, as well as the evolution of massive cosmic structures in general.
