#NASA released an audio clip of a #BlackHole, and it's pretty spooky

#NASA recently revealed that black holes emit noises that sound like ghostly alien moans and wails.

Listen to the clip below, where NASA captured the eerie sounds of #blackhole pressure rippling through the Perseus galaxy cluster.

"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," the @NASA account tweeted.

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. Then #NASA scaled the sounds up from their true pitch to something you can hear.

#NASA originally published the audio clip in May, but the post on Monday triggered an outpouring of new reactions online.

A Twitter account for the BlindBoy Podcast (@Rubberbandits) said the black hole sounded like "a billion souls being tortured."

When it first published this clip, #NASA also shared a more pleasant sonification of noise data from M87, the black hole that starred in the first #blackhole photo released by the #EventHorizonTelescope project in 2019.
