In today's APOD, through the electronic eyes of the NASA - Cassini Spacecraft, we can observe smooth, and sometimes wavy, contours in the banded East-West flowing Clouds of the Gas-Giant Planet Saturn. This view shows Clouds in Saturn's Northern Mid-Latitudes. The image was taken using a spectral filter sensitive to wavelengths of InfraRed Light centered at 727 nanometers. The view was obtained with the NASA - Cassini Spacecraft narrow-angle camera on July 8, 2007 at a distance of approx. 2,9 Million Kilometers (or MKM) (such as about 1,8 Million Miles - or MMs) from Saturn. Image scale is roughly 34 Km (such as about 21 miles) per pixel.


The NASA - CASSINI Original b/w frame 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 Upper Atmosphere of Satun), 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 in the Upper Atmosphere of Satun, each having a different Albedo (---> Reflectivity) and Chemical Composition.
