Today's APOD is an Extra Detail Magnification (or "EDM", for short) - obtained from a crop of yesterday's interesting Contextual Image (or "CTX Frame", for short) - of the Dwarf Planet 1-Ceres, taken by the NASA - Dawn Spacecraft on October, 7, 2015, which showed us an highly Cratered Terrain located (---> centered) at approx. North Latitude and 304° East Longitude, immediately to the West of the intriguing Mountain known as Ahuna Mons.


North on 1-Ceres is up. Here, we can see a small Unnamed Impact Crater, that is surrounded by Asymmetric Ejecta (a clear sign that the Impact was relatively oblique as to the Surface) which are composed of a mixture of (mostly) light (just as usual...) and dark Material, whose origin is still unknown.


The original photo was taken from an altitude of approx. 918 miles (such as about 1477,37412 Km) from the Surface, with a resolution of roughly 394 feet (such as about 120,0912 meters) per pixel.


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 20147 - Dawn HAMO Image 84) 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.
