The 'Voice' of our Earth (HD/3D)

"NASA Space Recordings of Earth" reveals our universe is not silent. Although space is a vacuum, sound exists as electromagnetic vibrations.

Specially designed instruments on board the Voyager and other probes captured these vibrations. These recordings fall within the range of human hearing (20-20,000 cycles per second).
