Black Holes, known for their endless darkness and void that does not even allow light to pass through them are one of the most powerful objects in the universe. Engineers at Nasa have now given this endless void a new identity as they release sounds coming from the black hole.
Engineers have converted the pressure waves sent out by the black hole into sound notes. This new sonification, a translation of astronomical data into sound, has been released for Nasa’s Black Hole Week this year. The waves that were released by the black hole in real are the ones that humans cannot hear some 57 octaves below middle C.
Sound engineers have used data from the Chandra X-Ray Observatory that observed the black hole at the center of the Perseus galaxy cluster.

“The popular misconception that there is no sound in space originates with the fact that most of the space is essentially a vacuum, providing no medium for sound waves to propagate through. A galaxy cluster, on the other hand, has copious amounts of gas that envelop the hundreds or even thousands of galaxies within it, providing a medium for the sound waves to travel,” Nasa said.
This is the first time that engineers have made the sound waves audible after extracting them in radial directions, that is, outwards from the center. Nasa said that the signals were then resynthesized into the range of human hearing by scaling them upward by 57 and 58 octaves above their true pitch.
The sound that you hear is 144 quadrillion and 288 quadrillion times higher than its original frequency.
Nasa has also released the sonification of the black hole in Messier 87, or M87, which gained celebrity status in science after the first release from the Event Horizon Telescope (EHT) project in 2019. The sound has been made from data from other telescopes like Hubble that observed M87 before the Event Horizon breakthrough image.
