(FILES) This handout photo realeased by the European Southern Observatory and taken on June 7, 2016 shows deep in the heart of the Abell 2597 Brightest Cluster Galaxy, a small cluster of giant gas clouds raining in on the central black hole.  First postulated more than 230 years ago, black holes have been extensively researched, frequently depicted, even featured in films. But here's the thing we're still not sure they even exist. On a quest for proof, scientists have trained a massive telescope in Chile on a point some 24,000 lightyears away, where a supermassive black hole is thought to lurk. / AFP PHOTO / European Southern Observatory / STRSTR/AFP/Getty Images
