The NASA - Cassini Spacecraft has been traveling the Saturnian System in a set of inclined, or "tilted", orbits that are giving to the mission scientists a vertigo-inducing view of Saturn's Polar Regions. This perspective has yielded images of roiling Storm Clouds and a swirling Vortex at the center of Saturn's famed North Polar Hexagon. This phenomenon mimic what Cassini found at Saturn's South Pole a few years ago. The Spacecraft has also seen several Storms circling Saturn's North Pole in the past, but only in InfraRed Wavelengths, since the North Pole was in complete darkness. But now, with the change of the Saturnian Season, the Sun has finally begun to creep over the Gas-Giant Planet's North Pole, which has therefore become visible even in the Wavelenghts of Visible Light. This particular image was taken on November, 27, 2012, with Cassini's Narrow-Angle Camera. The Camera, at the time the picture was obtained, was pointing toward Saturn from approximately 224.618 miles (such as about 361.488 kilometers) away.


This picture (which is an Original NASA - Cassini Spacecraft b/w frame identified by the n. IMG004677-br500) 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 North Pole of Saturn), 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 of Saturn, each having a different Albedo (---> Reflectivity) and Chemical Composition.
