A R C H I V E S

Today's APOD is an Extra Detail Magnification ("EDM") of yesterday's (just as usual) fascinating Contextual Image (or "CTX Frame", for short) of the Dwarf Planet 1-Ceres, taken by the NASA - Dawn Spacecraft on October, 14, 2015, which shows us a tall, and cone-shaped Mountain (maybe an ancient Volcano, whose Summit Caldera is now covered - actually, filled- up - by Rocks and Debris?) known as Ahuna Mons.

If you pay specific attention to the Summit of Ahuma Mons, you may be able to notice that its texture and color are different as to the texture and color of its Slopes, as well as of the surrounding Terrain. One possibility, if Ahuna Mons was, in fact, an ancient Volcano, is that its Summit - for reasons obviously unknown - collapsed on itself, thus "erasing" - litterally - the Caldera.

The White Striations visible on its Southern, Western and Eastern Slopes, as well as the (relatively) deep Channels located on its Northern Slopes, at the time, cannot be fully explained. However, in the future, maybe using some other picture - we hope taken from a closer distance -, we might be able to speculate a little more about this really unusual Relief. Ahuna Mons - which was so named after the traditional post-harvest festival of the Sumi tribe of Nagaland, India -, is about 4 miles (such as approx. 6,437 Km) tall, and roughly 12 miles (such as about 19,312 Km) wide.

The original photo was taken from an altitude of approx. 915 miles (such as about 1472,5461 Km) from the Surface, with a resolution of roughly 450 feet (such as about 137,16 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 20130 - Dawn HAMO Image 67) 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.
