Says Phil Plait, the Bad Astronomer, "On Oct. 10, 2013, Cassini took 36 shots of Saturn, a dozen each using red, green, and blue filters which approximate true color." Croatian software developer Gordan Ugarkovic took those 36 images (the equivalent of 12 true color photos) and composited them into one massive mosaic. The resulting image, while not technically geometrically accurate, is stunning. Plait's blog calls out some of the incredible detail you can see in the photo, including the characteristics of Saturn's individual rings (which are surprisingly flat), gaps, and moons.
