NASA has released an audio clip of sound waves of a black hole at the center of the Perseus galaxy cluster, which is located over 200 million light-years away.

"The sound waves astronomers previously identified were extracted and made audible for the first time," NASA's exoplanet team tweeted on Monday.

"The misconception that there is no sound in space originates because most space is a vacuum, providing no way for sound waves to travel," it said. "A galaxy cluster has so much gas that we've picked up actual sound."

NASA said the black hole has been associated with sound since 2003, astronomers discovered the pressure waves sent out by it "caused ripples in the cluster's hot gas that could be translated into a note." But humans couldn't hear it because its frequency was too low.

Astronomers remixed the sound and re-synthesized the signals, which are thus being heard "144 quadrillion and 288 quadrillion times higher than their original frequency," according to NASA.

The clip was first released in May, but the tweet by the exoplanets programs team set social media ablaze with 14.6 million views as of noon on Wednesday.

"Filtering the sound and making some adjustment to speed makes it almost as there's actually something speaking … Although it's an unrecognizable language," said a twitter account.

The Insider said "it's pretty spooky." "No surprise, the sound is terrifying," said USA Today.
