Unnamed Impact Crater near the North Pole of 1-Ceres (EDM)
Unnamed Impact Crater near the North Pole of 1-Ceres (EDM)

This is an Extra Detail Magnification (or "EDM", for short) obtained from the fascinating Contextual Image (or "CTX Frame", for short) of the Dwarf Planet 1-Ceres, taken by the NASA - Dawn Spacecraft on February, 12th, 2016, which shows us an ancient Unnamed Impact Crater and long Shadows which cast a "dark mood" on the whole scene, located near this magnificent Dwarf Planet's North Pole. Even in this case, some white Striations (whose origin is still unknown) can be - just barely - seen on the East-facing Inner Slopes of the Crater.


The Original View was centered at approximately 78° North Latitude and 5° 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 an Original NASA - Dawn Spacecraft's b/w and NON Map-Projected frame published on the NASA - Planetary Photojournal with the ID n. PIA 20563 - DAWN LAMO Image n. 68) 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.
