- NASA has shared the chilling sounds of a black hole emitting pressure waves rippling through galaxies.
- The ghostly alien moans and moans are cranked up 57 octaves for humans to hear.
- Another version of black hole sonification results in beautiful music. Listen to both below.
In the vacuum of space, you don’t hear much, but NASA recently revealed that black holes emit noises that sound like ghostly alien moans and moans.
In a Publish On Monday, NASA’s Twitter account for its exoplanet programs shared an audio clip of chilling sounds coming from pressure waves, rippling from a black hole through a cluster of galaxies.
Listen to the clip below, where NASA captured the eerie sounds of black hole pressure rippling through the Perseus Galaxy Cluster.
“The misconception that there is no sound in space stems from the fact that most of space is a ~vacuum, which does not allow sound waves to travel. A cluster of galaxies contains so much gas we picked up real sound,” the NASA account tweeted.
The actual sound, however, is outside the range of human hearing at 57 octaves below middle C. The Chandra X-ray Observatory captured data from the Perseus Cluster’s ripples, visible in X-rays, which corresponded to inaudible sounds. Then NASA scaled the sounds from their actual pitch to something you can hear. That’s 144 quadrillion and 288 quadrillion times higher than their original frequency.
originally NASA published the audio clip in May, but Monday’s post sparked a flurry of new reactions online.
“It’s cool – and really, really scary,” said CNN anchor Jim Sciutto wrote on Twitter.
A Twitter account for the BlindBoy podcast said the black hole looked like “a billion tortured souls”.
Canadian actress Elizabeth Bowen compared to “that scene in the movie where someone accidentally stumbles upon some kind of satanic cult in the middle of the woods.”
“Everyone says how weird it is, but to me the way it cuts in is by far the scariest part,” said astronomer blogger Phil Plait. said.
When it first released this clip, NASA also shared a nicer sonification of noise data from M87, the black hole that starred in the first black hole photo released by the Event Horizon Telescope project in 2019. .
This music is also sourced from x-ray data from the Chandra Telescope, but incorporates audio renditions of optical data from the Hubble Space Telescope and radio waves from the Atacama Large Millimeter Array in Chile. Because this combination of data required more creativity than simply raising the pitch of an existing sound, NASA made beautiful music out of it.
The loudest part of the M87’s music is the brightest part of the image, precisely where the black hole is.
