“Was not their mistake once more bred of the life of slavery that they had been living?—a life which was always looking upon everything, except mankind, animate and inanimate—‘nature,’ as people used to call it—as one thing, and mankind as another, it was natural to people thinking in this way, that they should try to make ‘nature’ their slave, since they thought ‘nature’ was something outside them” — William Morris

The Sound of Jupiter

They are well within the range of human hearing:

“The complex interactions of charged electromagnetic particles from the solar wind , planetary magnetosphere etc. create vibration "soundscapes". ... 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.”
