The space agency’s clip of the Perseus galaxy cluster, located 240 million light-years away, has gone viral on Twitter
On Sunday (August 21), NASA released an audio clip of what a black hole would sound like, and some are saying it sounds like Björk and Brian Eno.
The USA space agency tweeted what it called a remixed sonification of a black hole in the Perseus galaxy cluster, located approximately 240 million light-years from Earth.
According to NASA, the sound waves discovered there over two decades ago were “extracted and made audible” this year.
The video, which NASA referred to as a “Black Hole Remix,” was initially made available in early May to coincide with NASA’s Black Hole Week, but it wasn’t until the NASA exoplanets team tweeted on Sunday that it started to take off, garnering more than 15 million views.
The sound was first detected by NASA’s Chandra X-ray Observatory, and the space agency defined it as pressure waves emitted by the black hole at a whopping 57 octaves below middle C.
This suggests that to make the sound detectable, researchers had to elevate the frequency by quadrillions of times.
“Another way to put this is that they are being heard 144 quadrillion and 288 quadrillion times higher than their original frequency,” NASA said.
Kimberly Arcand, the principal investigator of the sonification project, told The Washington Post that she thought the recording sounded like “a beautiful Hans Zimmer score with the moody level set at really high”.
The 34-second clip caught people’s attention online and many remarked it sounded much like they expected a supermassive black hole would sound. It has been compared to an eerie cosmic growl or a menacing wind tunnel.
“Funny how this sounds like every Black Hole in every science fiction film EVER” says one Twitter user.
Others made light of the experimental-sounding nature of this recording, and likened it to electronic producers such as Björk and Brian Eno.
“New bjork sounds amazing”, jokes another user on Twitter. “new brian eno just dropped” jokes another.
“The universe is moaning and not in a sexy way”, says another person online.
The agency’s decision to make the nearly two-decade-old data’s “re-sonification” public is a part of its efforts to use social media to explain complicated scientific discoveries to its millions of followers.
