🪐 In the Perseus Cluster, a supermassive black hole at the center of the galaxy NGC 1275 sends out powerful sound waves that ripple through the surrounding gas. These cosmic vibrations have wavelengths so vast—spanning around 30,000 light-years—that they produce the deepest note ever detected, 57 octaves below middle C, making it a real, albeit inaudible, “song” of the universe. ✨ #PerseusCluster⚡#blackhole⚡#astronomy⚡#nasa⚡#galaxy⚡#stars⚡#universe⚡#cosmos⚡#space 👉subscribe Universe Mysteries
