The LRO can create images of the surface that are comparable to the highest resolution images taken of the Moon from orbit during the Apollo era. The original Lunar Orbiter images were the highest resolution images ever taken of the Moon from orbit prior to the LRO's photography. [ 11 ]

Since Peary is located nearly on the limb of the Moon as viewed from Earth, high-quality images of the crater were not available until space probes started photographing the Moon; the first high-quality images came from the US Lunar Orbiter 4 spacecraft. [1]
If you have a different image of similar quality, be sure to upload it using the proper free license tag, add it to a relevant article, and nominate it. This image was selected as picture of the day on the English Wikipedia for December 18, 2013 , and July 18, 2019 .
Lucky image of M15 core. Lucky imaging (also called lucky exposures) is one form of speckle imaging used for astrophotography.Speckle imaging techniques use a high-speed camera with exposure times short enough (100 ms or less) so that the changes in the Earth's atmosphere during the exposure are minimal.
Aegaeon is the smallest known moon of Saturn outside of the rings and has an extremely elongated shape, measuring 1.4 km × 0.5 km × 0.4 km (0.87 mi × 0.31 mi × 0.25 mi) in size. [9] Measurements of its mass show that Aegaeon has a very low density, likely due to a highly porous and icy interior structure. [ 5 ]
The Moon has been measured by the methods of laser altimetry and stereo image analysis, including data obtained during several missions. The most visible topographical feature is the giant far-side South Pole-Aitken basin , which possesses the lowest elevations of the Moon.
Since this is a telescopic view, this image is inverted. When the sun illuminates the feature at an oblique angle at about day 8 of the Moon's orbit, the Rupes Recta casts a wide shadow that gives it the appearance of a steep cliff. The fault has a length of 110 km, a typical width of 2–3 km, and a height of 240–300 m.
