Lightning in Saturn's atmosphere sounds like raindrops pattering on leaves, and the microwave radiation left over from the big bang is reminiscent of a vacuum cleaner running in the next room. These two sites let you listen to space, offering recordings of unearthly noises and various types of energy translated into frequencies we can hear. At Spacesounds,* a commercial site created by artists and scientists, you can tune in to the magnetosphere of Jupiter's moon Ganymede, the Vela pulsar, and other objects. Space-flight devotees can play hours of communications between ground control and the crews of the Apollo, Gemini, Mercury, and space-shuttle missions. The squeaks, chirps, roars, and other noises at Space Audio from the University of Iowa in Iowa City sound like they came from a David Lynch movie.
