Black Hole

Chandra's 53-hour observation of the central region of the Perseus galaxy cluster (left) has revealed wavelike features (right) that appear to be sound waves. The features were discovered by using a special image-processing technique to bring out subtle changes in brightness. These sound waves are thought to have been generated by explosive events occurring around a supermassive black hole (bright white spot) in Perseus A, the huge galaxy at the center of the cluster. The image also shows two vast, bubble-shaped cavities filled with high-energy particles and magnetic fields. They create the sound waves by pushing the hot X-ray emitting gas aside. The pitch of the sound waves translates into the note of B flat, 57 octaves below middle-C. This frequency is over a million billion times deeper than the limits of human hearing, so the sound is much too deep to be heard.

Like Bass? Scientists Have Found the Lowest Note in the Universe

Just as we puny humans like our beats and bass, the Universe as a whole likes a good thump, too. A supermassive black hole in the A supermassive black hole in the centre
