In this episode we look at the very strange occurrence of "moon music". Did the Apollo Ten astronauts really hear transmissions form an extraterrestrial source? Or is there a more down-to-earth explanation?

Also we take a listen to some of the most unnerving, unexplained sounds that continue to baffle experts.

Written, presented and produced by Chris Batchelor.
