This, in a way, very "dark", and yet beautiful picture, taken on August, 27, 2015, by the NASA - Dawn Spacecraft, shows us an ancient, highly irregular and heavily Cratered Sub-Region of the Dwarf Planet 1-Ceres; a Sub-Region that, as you can easily understand just by looking at the picture, is extremely close to the Terminator Line (or, maybe, it is just on top of it) of the Dwarf Planet itself.


Even this frame was obtained by the NASA - Dawn Spacecraft during the Mission's High Altitude Mapping Orbit (or "HAMO", for short) Phase, from which the Spacecraft imaged (and it is still imaging) the Surface of 1-Ceres at a resolution of about 450 feet (such as approx. 137,16 meters) per pixel.


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 19901 - Dawn HAMO Image 23) 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.
