NASA wants to dispel the myth of there being no sound in space, so they released a ‘Black Hole Remix’. More specifically, actual sound from a galaxy cluster that has been amplified and then mixed with other data, resulting in what the agency believes a black hole sounds like.
The misconception that there is no sound in space originates because most space is a ~vacuum, providing no way for sound waves to travel. A galaxy cluster has so much gas that we've picked up actual sound. Here it's amplified, and mixed with other data, to hear a black hole! pic.twitter.com/RobcZs7F9e

This new sonification of Perseus had its sound waves extracted in radial directions, or in other words, outwards from the center. These signals were then re-synthesized into the range of human hearing by scaling them upward by 57 and 58 octaves above their true pitch. This means that they are being heard 144 quadrillion and 288 quadrillion times higher than their original frequency. Now that you know what a black hole sounds like, here’s what it’s like to revolve around a black hole accretion disk.

The radar-like scan around the image allows you to hear waves emitted in different directions. In the visual image of these data, blue and purple both show X-ray data captured by Chandra,” said NASA.
