From an original CD: JUPITER NASA-VOYAGER SPACE SOUNDS (1990) BRAIN/MIND Research
Fascinating
recording of Jupiter sounds (electromagnetic "voices") by NASA-Voyager.
The complex interactions of charged electromagnetic particles from the
solar wind , planetary magnetosphere etc. create vibration
"soundscapes". It sounds very interesting, even scary.
Jupiter is
mostly composed of hydrogen and helium. The entire planet is made of
gas, with no solid surface under the atmosphere. The pressures and
temperatures deep in Jupiter are so high that gases form a gradual
transition into liquids which are gradually compressed into a metallic
"plasma" in which the molecules have been stripped of their outer
electrons. The winds of Jupiter are a thousand metres per second
relative to the rotating interior. Jupiter's magnetic field is four
thousand times stronger than Earth's, and is tipped by 11° degrees of
axis spin. This causes the magnetic field to wobble, which has a
profound effect on trapped electronically charged particles. This plasma
of charged particles is accelerated beyond the magnetosphere of Jupiter
to speeds of tens of thousands of kilometres per second. It is these
magnetic particle vibrations which generate some of the sound you hear
on this recording.
