A glowing shape that looks like a musical treble clef, hidden behind the dust and stars of our own galaxy, was created by a supermassive black hole outburst and later revived by a crash between two galaxy clusters, according to a NASA analysis using the Chandra X-ray Observatory. The structure sits "almost directly behind the plane of the Milky Way," NASA said, a part of the sky astronomers have long struggled to study.
