NASA releases the audio clip of Black hole that sounds ghostly

On Wednesday, The National Aeronautics and Space Administration (NASA) releases the audio clip of Black Hole that sounds very ghostly.

NASA Exoplanets on its official Twitter account shares an audio clip of ghostly sounds that come from waves of pressure, rippling from a black hole through a cluster of galaxies.

NASA Exoplanets tweeted, “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!”
However, the actual sound is out of the human hearing range at 57 octaves below middle C. The Chandra X-ray Observatory captured data from the ripples in the Perseus cluster, visible in X-ray, which corresponded to inaudible sounds, BusinessInsider reports.
NASA then scales the sounds up from their true pitch to something that human beings are able to hear. That’s 144 quadrillions and 288 quadrillion times higher than their original frequency.

NASA originally published the audio clip in May, but the post on Monday attracted many new reactions online.
