Outer space is a vacuum – it’s full of a whole lot of nothing – so it’s pretty quiet out there. Or is it? Sit back, strap yourself in and lift off into the great beyond. This episode of Sound Matters features Professor Tim O’Brien of Jodrell Bank Observatory in the UK and amateur radio satellite enthusiast Dave Rowntree (you might know him as the drummer in legendary Britpop band, Blur) looking at and listening to sounds from beyond our atmosphere. Also featuring sounds from the Voyager Space Probe, the planet Mars, black holes, pulsars, the solar wind, Russian cosmonaut Yuri Gagarin, the first space walk, the space shuttle, aliens, and more. Not so quiet up there anymore, eh?
