The "Dichotomy Boundary" on Titan (N-IR Light - Natural Colors; credits: Dr Paolo C. Fienga - Lunexit Team)

Caption NASA:"The Cassini Spacecraft records Titan's Seasonal Hemispheric Dichotomy, with the moon's northern half appearing slightly lighter than the southern half in this image.
This view looks toward the Trailing Hemisphere of Titan. North on Titan is up and rotated 12° to the right.

The image was taken with the Cassini Spacecraft narrow-angle camera on Feb. 16, 2010 using a spectral filter sensitive to wavelengths of Near-InfraRed Light centered at 889 nanometers. The view was obtained at a distance of approx. 1,1 MKM (such as about 684.000 miles) from Titan and at a Sun-Titan-Spacecraft, or Phase, Angle of 28°.
Image scale is roughly 7 Km (about 4,3 miles) per pixel".
