This Contextual Image of a (relatively) small portion of the Dwarf-Planet named 1-Ceres, taken by the NASA - Dawn Spacecraft on June, 25, 2015, shows us, once again (see, if you wish, the APOD of July, 3, 2015), a large, steep-sided Mountain and several - always intriguing and largely unknown - bright White Spots. The Mountain's height is now estimated to be about 4 miles (such as approx. 6,437 Km), which is a revision of the previous estimate of roughly 3 miles (such as about 4,828 Km). This Mountain is the highest point seen on 1-Ceres so far.

Just out of curiosity, this specific frame was obtained from an altitude of approx. 2700 miles (such as about 4345,218 Km).  The Resolution here is roughly 1400 feet (such as approx. 426,72 meters) per pixel.

The 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 19615 - Dawn Survey Orbit Image 42) has been additionally processed, 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.
