These always blow my mind. Here are all 5 recordings of NASA's Voyager sailing through our solar system.
Possibly one of NASA's most avant-garde projects ever, SYMPHONIES OF THE PLANETS is a five-CD set that is now out of print. Put simply, it consists of recordings made by Voyager 1 and Voyager 2 as they passed by the various planets and moons of our solar system. Although sound as we perceive it cannot travel in the vacuum of space, each planet and moon emits its own electromagnetic "signature" that can be picked up by the right instruments, and those emanations can be converted into sound and recorded onto compact discs for your listening enjoyment.
Of the five discs in the set, Volume 1 is my personal favorite, but all of them are definitely worth checking out. Each disc is only around 30 minutes long, but those 30 minutes are packed with cosmic ambience that is even more profound when you consider that no human artist composed this. Fans of Dr. Fiorella Terenzi's similar recordings of space will find this stuff to their liking, although a bit more "dark" and atmospheric than hers.
A 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.
