  Titan's seasonal hemispheric dichotomy is chronicled in black and white, with the moon's northern half appearing slightly lighter than the dark southern half.

See PIA11603 to learn more about this change on Titan. This view looks toward the Saturn-facing side of Titan (5150 kilometers, 3200 miles across). North on Titan is up.

The image was taken with the Cassini spacecraft narrow-angle camera on Oct. 16, 2009 using a spectral filter sensitive to wavelengths of near-infrared light centered at 889 nanometers. The view was obtained at a distance of approximately 2.6 million kilometers (1.6 million miles) from Titan and at a Sun-Titan-spacecraft, or phase, angle of 71 degrees. Image scale is 16 kilometers (10 miles) per pixel.

The Cassini Equinox Mission is a joint United States and European endeavor. The Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the mission for NASA's Science Mission Directorate, Washington, D.C. The Cassini orbiter was designed, developed and assembled at JPL. The imaging team consists of scientists from the US, England, France, and Germany. The imaging operations center and team lead (Dr. C. Porco) are based at the Space Science Institute in Boulder, Colo.

the difference is subtle, but clearly visable on this computer. i wonder if it is raining under the darker clouds. once again the Saturn system hands us an intriging mystery.
