DECEMBER 23: In this June 16, 2011 photo distributed today, Saturn's largest and second largest moons, Titan and Rhea, appear to be stacked on top of each other in a true-color scene from NASA's Cassini spacecraft. The images were taken using red, green and blue spectral filters that were combined to create this natural-color view. (NASA/JPL-Caltech/Space Science Institute)
