While space is technically a vacuum, sound still exists in space. For some time now, NASA has used specially designed Plasma Wave antennas on its space probes to record electromagnetic vibrations within human hearing range (20-20,000 Hz). These electromagnetic waves come from interaction between the ionisphere, planetary magnetosphere, and the solar winds. Pretty cool, huh?
Recently NASA took a sample from a dozen different recordings of celestial objects (Saturn’s rings, Neptune, Earth, Uranus, Jupiter, etc) and compiled it into the above video. The result is something like a sci-fi soundtrack crossed with 1980’s whale sounds. It’s intriguing, strange, even a little eery, but mostly just very awesome. Give it a listen!
