The South Polar Atmosphere of Titan (CTX Frame - Natural Colors; credits: NASA/JPL-Caltech/Space Science Institute)

Caption NASA:"These views from NASA's Cassini Spacecraft look toward the South Polar Regions of Saturn's largest moon, Titan, and show a "Depression" within the moon's Orange and Blue Haze Layers visible near the South Pole. The EDM (close-up) view of these features was captured with the narrow-angle camera.
Titan's High Altitude Haze Layer appears Blue here whereas the Main Atmospheric Haze is orange. The difference in color could be due to particle size of the Haze. The Blue Haze likely consists of smaller particles than the ones forming the Orange Haze. The "Depressed" or "Attenuated" Layer appears in the Transition Area between the Orange and Blue Hazes.

Images taken using red, green and blue spectral filters were combined to create this Natural Color view. The images were obtained on Sept. 11, 2011 at a distance of approximately 83.000 miles (about 134.000 Km) from Titan. Image scale is 2581 feet (787 meters) per pixel".
