This image, taken from Apollo 12 (CSM Yankee Clipper) while orbiting around the Moon, shows the Lunar Terminator, such as the line separating Daylight from Darkness. The Objects (---> Surface Features) located near the Terminator usually appear higher and sharper than what they actually are, and this fact is due to the low Sun angle (which makes them project, therefore, very long and extremely sharp shadows). The Crater Gambart is visible on the Terminator, towards the North (such as the upper part) of the frame. Gambart Crater is approx. 25 Km in diameter and it is centered at about 1° North Latitude and 15,2° West Longitude. The area in this photograph is just to the North/East of the Apollo 14 Landing Site, in Fra Mauro. For the most curious Observers, we wish to underline and remind you that, when pictures like this one are taken, sometimes it is possible that our eyes can be deceived, and then, thanks to both the extremely sharp contrast between light and dark, as well as the long, pointed shadows that come from the Surface Features laying on or near the Terminator, we might lead to see unusually-looking Surface Features (like "squares" and "pyramids") when, in fact, nothing like that is really there and we are just looking at Hills, Mountains, Ridges and Crater Rims. This is the reason why we, as the IPF, have created, to define, once and for all, these "tricks of light and shadows", the word "Pseudo-Artifacts" (i.e.: Pseudo-Pyramids, Pseudo-Buildings etc.). This frame has been contrast enhanced and then colorized in Absolute Natural Colors (such as the colors that a human eye would actually perceive if someone were onboard the Apollo 12 - CSM Yankee Clipper - and then looked down, towards the Surface of the Moon), by using an original technique created - and, in time, dramatically improved - by the Lunar Explorer Italia Team. |
