Acoustic waves coming out of the black hole at the heart of the Perseus cluster of galaxies were transposed up 57 and 58 octaves in order to make them audible for human ears.
US space agency NASA has recorded an eerie audio clip that captures sound waves coming out of a supermassive black hole situated 250 million light years away. The acoustic waves, coming out of the black hole located at the heart of the Perseus cluster of galaxies, were transposed up 57 and 58 octaves to make them audible for human ears.
The audio was released in 2022 and it was the first time when the sound waves were extracted and made audible.
Sound waves do exist in space, even though we might not be able to hear them naturally.
In a surprising discovery in 2003, astronomers detected acoustic waves rippling out through the huge amounts of gas surrounding the supermassive black hole at the Perseus galaxy cluster, which is now popular for its eerie wails.
