It’s true that sound waves can’t travel in space. However electromagnetic and gravitational waves can. Now, a new album, Celestial Incantations, has turned these signals such as the oscillations of a comet, radiation from a galactic pulsar and the merger of two black holes into musical tracks. The album is a collaboration between Kim Cunio, an associate professor and convenor of musicology at the Australian National University, UK artist Diana Scarborough and Dr Nigel Meredith from the British Antarctic Survey. For those looking for a sonic journey through the cosmos, the album is free to stream and download
