Perseus Cluster




In 2003 , Astronomers detected the deepest Note ever generated in the Cosmos , a B-flat . No human will actually hear the note, because it is 57 Octaves below the keys in the middle of a piano. After 53 hours of Chandra observations, it was revealed that the detected note is more than 1,000,000,000,000,000 times deeper than what humans are able to hear. The reason the sound was detected was because the sound waves were heating gas in the Perseus galaxy cluster, some 250 million Light-years away.
