The NASA - Cassini Spacecraft peers through the hazy Atmosphere of Titan for a close view of light and dark Terrain on Saturn's largest moon. This view, that is centered at 28° South Latitude and 334° West Longitude, shows us a small part of the Albedo Feature named Senkyo (actually it is a very large Region that the Planetary Scientists consider like a true Continent) which is located on the Trailing Hemisphere of Titan.


The image was taken with the NASA - Cassini Spacecraft Narrow-Angle Camera on July 9, 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 251.000 Km (such as about 156.000 miles) from Titan and at a Sun-Titan-Cassini Spacecraft, or Phase, Angle of 27°. Image scale is about 1 Km (such as 3281 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 11577) 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.
