Smooth-Walled Unnamed Impact Crater on 1-Ceres (EDM)
Smooth-Walled Unnamed Impact Crater on 1-Ceres (EDM)

This is an Extra Detail Magnification ("EDM") of yesterday's simply great Contextual Image (or "CTX Frame", for short) of the Dwarf Planet 1-Ceres, taken by the NASA - Dawn Spacecraft on February, 8th, 2016, which showed us (as a matter of fact, truly WELL, in this EDM) a smooth-walled, and still Unnamed Cerean Impact Crater, located in the Northern Hemisphere of this truly "strange and intriguing" Celestial Body. Please notice the extremely uneven Floor of the aforementioned Unnamed Impact Crater (and this circumstance could be - but this is just a speculation - an obvious consequence of other Impacts that occurred nearby, which were followed by some kind of a "rain" of Rocks, Dust and Ejecta").


The Original View was centered at approximately 65° North Latitude and 155° East Longitude. 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 20552 - DAWN LAMO Image n. 57) 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.
