Today's APOD is an High Resolution Image-Mosaic of the Uranian moon, Miranda. One Wide-Angle and 8 (eight) Narrow-Angle Camera images of Miranda (all taken by the NASA - Voyager 2 Space Probe) were combined in order to obtain this view. The controlled mosaic was afterwards transformed into an Orthographic View (---> means to represent a three-dimensional object in two dimensions only) of this Celestial Body, with center on its South Polar Regions. The Trapezoidal Region (which is about 200 Km on each side and that can be seen near the Western Limb of the moon) lies very close to the South Pole of Miranda, while the Trapezoid's Outer Boundary and its internal pattern of Ridges and Bands of contrasting Albedo (---> Reflectivity) display a real big number of sharp corners. This frame has been 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 - Voyager 2 Space Probe and then looked outside, towards the Uranian moon Miranda), 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 Materials (for instance: Rock and Ice) and Minerals on the Surface of Miranda, each having a different Albedo and Chemical Composition. |
