Cornelia Crater (Absolute Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga/Lunar Explorer Italia/Italian Planetary Foundation)

This frame shows us a consistent number of examples of long, narrow and sinuous Gullies that scientists on NASA's Dawn Mission have found on the Giant Asteroid 4-Vesta. The Impact Crater shown here is called Cornelia and the Gullies inside it - called "Type-B" Gullies - are different substantially from the straighter, wider, shorter Gullies that Planetary Scientists have found on different Celestial Bodies (like the ones located on the Rims of many Martian Impact Craters, for instance) and which are designated as "Type-A" Gullies (and the reason of such a distinction is found in the circumstance that these two Gully-types have different formation mechanisms). This picture was obtained by the NASA - Dawn Spacecraft Framing Camera on January 11, 2012; North is up.

This frame (which is an Original NASA - Dawn Spacecraft b/w image published on the NASA - Planetary Photojournal with the ID n. PIA 16489) 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 - Dawn Spacecraft and then looked outside, towards the Surface of the Giant Asteroid 4-Vesta), 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 on the Surface of 4-Vesta, each having a different Albedo (---> Reflectivity) and Chemical Composition.
