NASA Released the Eerie Sound of a Black Hole

NASA has revealed what a supermassive black hole 250 million light years away from Earth sounds like. The object is located at the center of the Perseus cluster of galaxies.

The space agency has published a new audio clip of eerie sounds, which essentially are pressure waves that travel through galaxies and remain elusive to a human hearing under normal conditions. NASA scientists converted these waves into sounds so that we could finally hear them.

“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,” NASA said on Twitter.

As far back as 2003, scientists discovered that the pressure waves emitted by a black hole in the Perseus constellation caused ripples in the hot gas around the galaxy cluster. This data has now made it possible to recreate the sounds of the black hole. The acoustic waves have been transposed up 57 and 58 octaves upwards so that the human ear can pick them up.
