Understanding the universe isn't just about visually mapping celestial bodies, it's also about listening to the heavens. Data sonification takes astronomical data and turns it into sound. It could help find new patterns in the huge amount of digital information. And it's a way of enhancing astronomy by promoting greater engagement and accessibility — a musical mix of science, art and cold, hard data. Bruce Walker, professor in the School of Psychology and the School of Interactive Computing, and director of Georgia Tech's Sonification Lab, joins a panel of scientists for an April 15 program on what sonification can add to astronomy.
