Saturn and Titan
Saturn and Titan Cassini captured this stunning view of Saturn and Titan from nearly behind the pair on 11 August 2013. NASA / JPL-Caltech / SSI / Gordan Ugarkovic

Original images: red - green - blue. The green and red frames were at only half the full resolution of the camera; only the blue frame was at full resolution.

A different version of this image, processed by Emily Lakdawalla, was originally posted here. Gordan Ugarkovic's is better, so the image has been replaced.
