If we could listen to a black hole: the sound released by NASA is “terrifying”

Thanks to the sonication process, NASA created a truly sinister black hole “song”! Listen to the result

Since 2003, Black hole in the middleA group of galaxies Perseus (Abel 426) was associated with sound. This is because astronomers found that pressure waves emanating from the black hole caused ripples in the hot gas in the cluster that could be translated into a tone that humans cannot hear. About 57 octaves below middle C. Sonication is possible thanks to the difference in brightness: the frequencies can be translated into a signal that humans can also hear. The result is simply wonderful The following video is proof of this:

Sonication

The idea that there is no sound in space stems from the fact that most of space is essentially a vacuum, providing no means of propagation of sound waves. The sound waves, in this case, were extracted in radial directions, i.e. outward from the centre. The signals were then summed back into the human hearing range by raising them 57 and 58 octaves above the true pitch.

Lots of gas

On the other hand, a galaxy cluster contains abundant amounts of gas enveloping hundreds or even thousands of galaxies within it, providing a means for sound waves to travel. In this new sonification of the Perseus galaxy group It is about 240 million light-years away from Earth (Part of the supercluster called Perseus-Pisces), sound waves previously identified by astronomers have been extracted and made audible for the first time with the remarkable result you've just heard.
