When bumped up to human frequencies, the sounds of the black hole are almost akin to the wails of a haunting ghost or the deep ocean calls of a pod of whales.
, a massive space structure that's 11 million light-years across and located about 240 million light-years away from Earth. Astronomers created the audible sound by recording the pressure waves that the black hole sent through the cluster's hot gas. In their original form, those waves cannot be heard by the human ear, so scientists extracted the sound waves and scaled them up by 57 and 58 octaves.
"In some ways, this sonification is unlike any other done before," NASA said in a release."...[The sound waves] are being heard 144 quadrillion and 288 quadrillion times higher than their original frequency." While this particular sound of space is new, NASA has associated the Perseus galaxy cluster with sound since 2003. Galaxy clusters like Perseus are the largest gravitationally bound objects in the universe containing hundreds of galaxies, massive clouds of hot gas that reach more than 180 million degrees Fahrenheit and the ever-mysterious dark matter. All of that material creates a medium for sound waves to travel.
Along with releasing the sounds of Perseus, NASA scientists have also released a sonification of another famous black hole located in Messier 87, or M87.
