NASA releases audio of sound of black hole

NASA has released a haunting audio clip of sound waves rippling out of a supermassive black hole, located 250 million light-years away.

• The recording is created from the soundwaves of a black hole at the centre of Perseus galaxy cluster.
• According to NASA, it is a common misconception that there is no sound in space.
• Most of space is vaccum, so there is no way for sound waves to travel – but the Perseus galaxy cluster is surrounded by thick gases that rippled when the black hole sent out pressure waves.
• In this sonification of Perseus, the sound waves astronomers previously identified were extracted and made audible for the first time.
• The sound waves were extracted outward from the center.
• The acoustic waves coming from it have been transposed up 57 and 58 octaves so they're audible to human hearing.

Sonification:

• Sonification is the use of non-speech audio to convey information.
• It involves converting data into sound so that the relationships within the data can be perceived, explored and enjoyed with our exquisite auditory system.
• In short, sonification is taking data and making it into sound.
