The NASA - Cassini Spacecraft peers through the Dark and Hazy Atmosphere of Titan, this time looking at a Region called Adiri, and located to the West of the Landing Site of the ESA - Huygens Probe, on the Anti-Saturn Side of the moon. This view is centered on Terrain at 22° South Latitude and 209° West Longitude. North on Titan is up and rotated 36° to the right. The dark Circular Feature visible slightly on to the right of the image center, at about 2 o'clock (and that looks like a well preserved Impact Crater seen from atop), could actually be an Image-Artifact.


The image was taken with the NASA - Cassini Spacecraft Narrow-Angle Camera on December 12, 2009, using a spectral filter sensitive to Wavelengths of Near-InfraRed Light centered at 938 nanometers. The view was obtained at a distance of approximately 130.000 Km (such as about 81.000 miles) from Titan. Image scale is 766 meters (such as 2513 feet) per pixel.


This picture (which is an Original NASA - Cassini Spacecraft b/w frame published on the NASA - Planetary Photojournal and identified by the n. PIA 12621) has been additionally processed and then colorized, according to an informed speculation carried out by Dr Paolo C. Fienga (LXTT-IPF), in Absolute Natural Colors (such as the colors that a human eye would actually perceive if someone were onboard the NASA - Cassini Spacecraft and then looked outside, towards the Saturnian moon Titan), by using an original technique created - and, in time, dramatically improved - by the Lunar Explorer Italia Team. Different colors, as well as different shades of the same color, mean, among others, the existence of different Elements present in the Atmosphere and on the Surface of Titan, each having a different Albedo (---> Reflectivity) and Chemical Composition.


Note: it is possible (but we, as IPF, have no way to be one-hundred-percent sure of such a circumstance), that the actual luminosity of the Albedo Feature seen in this frame would appear, to an average human eye, way lower than it has been shown (better yet: interpreted) here.
