In the close-up from the Cassini spacecraft, some of Saturn’s rings look rather like grooves in a phonograph record. I wonder if anyone has tried mapping those grooves to see if they can be played using the method described in “Groovy Pictures: Extracting sound from images of old audio recordings” (SN: 5/29/04, p. 339: Groovy Pictures: Extracting sound from images of old audio recordings). Obviously, some artistic license would need to be taken, but what a challenge to create true music of the spheres.
