NASA adapted sounds from a black hole for human hearing
Space agency specialists have recorded sounds from a black hole. The initial data was taken from the space in the center of the Perseus cluster.

The Perseus cluster is located more than 200 million light-years from our planet. Sounds are emitted by hot gas, and in order to hear them, experts raised their pitch by 58 octaves.



Sonification (translation of data into sound) was carried out by increasing the height of sound waves by 57 and 58 octaves, which is 144 quadrillion and 288 quadrillion times greater than their original height. As a result, the black hole sounds like an endless Do note. This study tells us that outer space is far from silent, even though it is mostly a vacuum. Nevertheless, clusters of galaxies contain huge volumes of gas, which becomes the source of sound waves.

In a short video posted by NASA, you can hear sounds compiled from three sources: X-rays from the Chandra Observatory (responsible for high tones), optical light from the Hubble Space Telescope (responsible for mid-tones) and radio waves received by the radio telescope complex from the desert Atacama, located in Chile (responsible for low tones).
