Unnnamed Impact Crater near Urvara Crater (EDM)
Unnnamed Impact Crater near Urvara Crater (EDM)

This is an Extra Detail Magnification ("EDM") of yesterday's beautiful Contextual Image (or "CTX Frame", for short) of the Dwarf Planet 1-Ceres, taken by the NASA - Dawn Spacecraft on October, 14, 2015, that shows us a medium-sized, extremely ancient and still Unnamed Impact Crater, located in the proximities of the huge Urvara Crater, which is characterized by a truly unusually-looking Central Peak. The nature of such a Peak (better yet: a Ridge-like Feature, or even some sort of a large and long Mountain) is still unknown.

The original photo was taken from an altitude of approx. 915 miles (such as about 1472,5461 Km) from the Surface, with a resolution of roughly 450 feet (such as about 137,16 meters) per pixel.

This image (which is a crop obtained from an Original NASA - Dawn Spacecraft's b/w and NON Map-Projected frame published on the NASA - Planetary Photojournal with the ID n. PIA 20128 - Dawn HAMO Image 65) has been additionally processed, extra-magnified to aid the visibility of the details, contrast enhanced and sharpened, Gamma corrected and then colorized (according to an educated guess carried out by Dr Paolo C. Fienga-LXTT-IPF) in Absolute Natural Colors (such as the colors that a normal human eye would actually perceive if someone were onboard the NASA - Dawn Spacecraft and then looked down, towards the Surface of 1-Ceres), by using an original technique created - and, in time, dramatically improved - by the Lunar Explorer Italia Team.
