Background Document: Astronomers Capture First-Ever Image of Two Black Holes Orbiting Each Other ### Introduction A groundbreaking discovery has been made in the field of astronomy, where scientists have captured the first-ever image of two supermassive black holes orbiting each other within a distant quasar named OJ 287. This historic observation confirms a 40-year-old forecast and provides a new window into the creation, movement, and collision of black holes.
### The Quasar OJ 287 The quasar OJ 287 is a brilliant light source fueled by supermassive black holes. It was first inadvertently photographed in early surveys of the skies in the 19th century. At that time, no one had even heard of black holes, and no one could ever have guessed what those little points of light were. ### The Discovery It was not until 1982 that graduate student Aimo Sillanpää, at the University of Turku in Finland, was able to see the repeating cycle of brightness in the data. He proposed that the periodic cycle was only explicable if two black holes were gravitationally bound together in orbit, distorting the stream of gas around them [1].
Astronomers had long suspected that certain quasars—those brilliant, otherworldly light sources fueled by supermassive black holes—could harbor two ...Other related sources and context: Visit website
