For the first time, astronomers have managed to capture a radio image showing two black holes orbiting each other in quasar OJ287. The observation confirmed the existence of black hole pairs. In the past, astronomers have only managed to image individual black holes.

Really cool. Any astronomers not affiliated with the publication able to chime in here? That paper is *dense*.
For it to orbit every 12 years must mean it’s a humongous orbit?!
