Swinburne University Astrophysicist Dr Sara Webb says the audio of a black hole was “very spooky” but not surprising as black holes do a lot to the environment surrounding them.
NASA has released audio of a black hole using a process known as sonification, which re-synthesises the soundwaves into the range of human hearing.
“So, what we’re hearing is those pressure waves radiating out from this rotating black hole and hitting all that hot dust and gas,” Dr Webb told Sky News Australia. “The process of sonification is incredible cause it means we can take data which is really just numbers in a computer and transfer it into something more enjoyable for us to try and understand because if it was just numbers, it wouldn’t be as wow would it”.

Skilled migrants key to ‘help overcome’ Australia’s job crisisA new report by Deloitte argues that skilled migrants and simpler pathways to permanent residents could help Australia overcome its job crisis. Deloitte Global Employer Services Partner Fiona Webb says Australia needs to send a stronger message to migrants that its open for business. Ms Webb also said looking at other measures such as expanding the amount of humanitarian visas Australia accepts could help overcome its job crisis. “There’s huge untapped potential in that skillset and that talent pool that we’re really not capitalising on and also in terms of numbers we readily welcome into the country,” she told Sky News Australia.

NASA releases audio of black holeNASA has released audio which represents sound waves coming from a black hole at the centre of the Perseus galaxy cluster. Galaxy clusters often release large amounts of gas, providing a medium through which sound waves can travel. The original noise is too low for the human ear to detect because it is 57 octaves below middle C, according to NASA. The process of sonification was used to translate the notes into sounds humans can hear.
