Photos of the Day: December 24, 2013

This June 16, 2011 photo provided by NASA/JPL-Caltech/Space Science Institute shows Saturn's largest and second largest moons, Titan and Rhea, appearing to be stacked on top of each other in this 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.
