Sound of Solar System
Captured by NASA
Since the interplanetary space is almost vacume, sound can not travel as it need some medium to transfer from one place to another. But electromagnetic wave is present close to all heavenly bodies which emmit at same wavelengths as audible sound (20 to 20,000 Hz) capable of human hearing.
Various NASA instruments, such as Voyager I and II, INJUN 1, ISEE 1 and HAWKEYE space probe, recorded electromagnetic waves close to many planets and their moons and send those signals back to Earth. These instruments used plasma wave antenna to record vibration in audible 20 to 20,000 Hz range. These electromagnetic waves are produced due to complex interaction of charged electromagnetic particles from Solar wind, ionosphere and planetary magnetosphere. These sounds from various space crafts are translated into sounds we can hear. In this video you can listen some of the sample of sounds made by solar system planets such as Jupiter, Saturn, Uranus, Neptune and their Moons.
Some of these sounds are very dramatic and some are monotonous (and boring) but neverthless they are very interesting.
