In space no-one can hear you sing...

Space. A place few men or women have gone before ... but plenty of composers have. The universe has inspired musicians for hundreds of years and consequently we all know what space music sounds like. Or do we?

From Holst and David Bowie to John Williams via Ligeti, Thomas Ades and the Beastie Boys, Tom Service dons his spacesuit on a mission to explore why cosmic-inspired music sounds the way it does, and discovers how space science is just as inspired by music as musicians are by space.

En route to the stars, space scientist Lucie Green is on hand to tell Tom the reality of sound in space, while mathematician Elaine Chew helps him uncover the music of the spheres.
