'NASA Space Recordings Of Earth'
Our Universe Is Not Silent~ Although space is a vacuum, that does not mean there is no sound in it.
Sound does exist in space.. in the form of electromagnetic vibrations.
Astronomical bodies emit radio waves which can be captured by the specially designed instrument known as 'astronomical interferometer'. This device can extract sound from the radio waves within the range of human hearing (20-20,000 Hz). Voyager and Hawk-eye are among many probes which record space sounds.
