A supermassive black hole at the heart of a galaxy cluster sends pressure waves through hot gas — real sound, just far too low for human ears.
What you’re hearing
Scientists raised the pitch by 57–58 octaves so you can hear it. The sound grows outward from the center, the way the waves actually travel through the cluster.
