Images of space are ubiquitous in our lives. We have been surrounded by stunning portrayals of our own solar system and beyond for generations. But in popular culture, we have no sense of what space… Radio Astronomy reflects our fascination with how audio can be used to understand information or ideas. Just as scientists visualize data through charts and pictures, we can use ‘data sonification’ to translate radio signals into sound that help us better understand some of our most enigmatic planetary systems. Astrophysicist Donald Gurnett and his team used data sonification to create an aural vocabulary for Jupiter and Saturn. Their sonifications of plasma waves of the Jovian moons, Ganymede , Europa and Callisto are amongst the most musical of the recordings we have encountered. Sonified plasma waves make a violent shaking sound, which then evolves into a loud melodic ‘twinkling’ sound.
