Saturn, and its various satellites, to be more specific.
Cassini has been a spectacularly successful mission, by any standard, documenting conditions on Titan, finding water geysers on Encedalus, providing clues to the forces that form and maintain Saturn's splendid rings, and much more. It also has returned some of the most beautiful imagery of a member of the solar system thus far.
Enter Chris Abbas, who has taken the raw, uncorrected imagery, and produced a dazzling little film. It's is absolutely gorgeous, and makes just about perfect use of the 'open source' Ghosts music project, by Nine Inch Nails.
