Why you should listen
Matt Russo co-founded the art-science project SYSTEM Sounds and works to make astronomy more accessible to the visually impaired. His work has been featured in the New York Times, and he will lead an orchestra in an upcoming BBC documentary on the TRAPPIST-1 planetary system. He is currently a professor at Seneca College in Toronto, Canada, where he teaches a course on the deep connections between music and astronomy.
