This Spooky Audio Represents The Plasma Waves Interaction Between Saturn And Its Moon 'Enceladus'

        US Space Agency NASA, in a recent video, has released an eerie sound that was captured by its Cassini spacecraft last year during its mission around the solar system's second largest planet, Saturn. The otherworldly sound has been converted from a recording of the interaction of plasma waves between the planet and its moon Enceladus, in a research led by physicist and RPWS Principal Investigator Bill Kurth, at the University of Iowa. The result, as one can listen to, hints at a powerful and dynamic interaction of plasma waves between the two celes bodies.

NASA's Cassini spacecraft had recorded the plasma wave interplay between Saturn, its moon Enceladus as well as the Saturn's rings through Radio Plasma Wave Science (RPWS) instrument on board. The recording was made on September 2 last year as Cassini prepared for its final plunge into the planet's atmosphere within a couple of weeks recording the wave play. 

During the research, the recording was converted into an audio file, with the total recording time being compressed to 28.5 seconds from its original 16 minutes. The process used for the conversion was similar to how electromagnetic waves are converted to music within a radio.
