This is an Extra Detail Magnification ("EDM") obtained from yesterday's wonderful Contextual Image (or "CTX Frame", for short) of the Dwarf Planet 1-Ceres, taken by the NASA - Dawn Spacecraft on February, 16th, 2016, that showed us a relatively small portion of Zadeni Crater (approx. 80 miles - such as about 128,7472 Km - wide). Zadeni Crater is a prominent Impact Feature located in the Southern Hemisphere of 1-Ceres and what you see here is a relatively recent (of course, Geologically speaking) Unnamed Impact Crater located inside it.

The (relatively) "clean"  (---> sharp) Rim, the bright and smooth Inner Slopes as well as its (barely visible portion of the) Interior speak from themselves.

The NASA - Dawn Spacecraft captured the scene during its Low-Altitude Mapping Orbit (or "LAMO", for short), from an approx. altitude of 240 miles (such as about 386,2416 Km) above the Surface of 1-Ceres. The Image Resolution is roughly 120 feet (i.e. about 36,576 meters) per pixel (---> Picture Element).

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 20574 - DAWN LAMO Image n. 79) 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 ahead, towards the Surface of 1-Ceres), by using an original technique created - and, in time, dramatically improved - by the Lunar Explorer Italia Team.
