Cassini passed within 22,000 kilometers of the moon on February 13, 2010, for the best look yet at its smooth, icy surface. This view is a color composite from Cassini's raw images, red, green, and blue frames overlaid on a stacked composite of red, green, blue, and clear images. (Stacking mostly serves to decrease the artifacts caused by the JPEG format of the raw images.)
