Haunting Audio From A Black Hole (NASA Records)

The audio, released on May 4, is that of a black hole from the center of the Perseus galaxy cluster, 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.“ #Nasa #space #BlackHole
