Unnamed Impact Craters on 1-Ceres (EDM)
Unnamed Impact Craters on 1-Ceres (EDM)

This Extra Detail Magnification (or "EDM", for short) has been obtained from yesterday's beautiful Contextual Image (or "CTX Frame", for short) of the Dwarf Planet 1-Ceres, taken by the NASA - Dawn Spacecraft on January,  1st, 2016, which showed us two - always Geologically speaking - "young" (---> "fresh") and Unnamed Impact Caters. The larger of the two, which can well be seen here in this EDM, is about 10 miles (such as approx. 16,09 Km) in diameter.

Many Surface Features visible in the surrounding Area (please, look at yesterday's APOD if you wish) have been subdued - or even erased away - by a (relatively) smooth Blanket of Ejecta which were (most likely) blasted out of the two Impat Craters during their formation. Furthermore, large Blocks of Ejected Material fell near the Rims of the two Craters and, in particular (as you can see VERY well in this EDM), they fell onto the Floor of the larger one. Two Striations (better yet: two small-sized "Spots") of white and bright (and still unknown) Material are clearly visible at about 11 o'clock on the Inner Rim of the pictured Impact Crater.

The Original Frame was centered at about 23° South Latitude and 279° East Longitude. The NASA - Dawn Spacecraft captured the scene during its Low-Altitude Mapping Orbit (or "LAMO", for short), from an approx. altitude of 229 miles (such as about 368,538 Km) above the Surface of 1-Ceres. The Image Resolution is roughly 112 feet (i.e. about 34,1376 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 20310 - DAWN LAMO Image n. 20) 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.
