Topography of the Moon. STL 3D model of the Moon with 10× elevation exaggeration rendered with data from the Lunar Orbiter Laser Altimeter of the Lunar Reconnaissance Orbiter. Selenography is the study of the surface and physical features of the Moon (also known as geography of the Moon, or selenodesy). [1]
The Moon then wanes as it passes through the gibbous moon, third-quarter moon, and crescent moon phases, before returning back to new moon. The terms old moon and new moon are not interchangeable. The "old moon" is a waning sliver (which eventually becomes undetectable to the naked eye) until the moment it aligns with the Sun and begins to wax ...
The lunar phases and librations in 2019 in the Northern Hemisphere at hourly intervals, with music, titles, and supplemental graphics Simulated views of the Moon over one month, demonstrating librations in latitude and longitude. Also visible are the different phases, and the variation in visual size caused by the variable distance from the Earth.
Original - Animation of the Moon as it cycles through its phases, as seen from the Northern Hemisphere. Update option for 2009 (Apparently has a darker (more realistic) ambient (earthshine) light, maybe I should brighten?) Reason It is an animation of excellent quality which clearly depicts lunar phases and libration. Articles this image appears in
Lunar theory attempts to account for the motions of the Moon. There are many small variations (or perturbations ) in the Moon's motion, and many attempts have been made to account for them. After centuries of being problematic, lunar motion can now be modeled to a very high degree of accuracy (see section Modern developments ).
The NASA astronauts who became the first people to land on the moon's surface in the 1960s and 1970s also discovered a previously unknown lunar characteristic - it has an atmosphere, though quite ...

Using the new method, one tonne of lunar soil will be able to produce about 51-76 kg of water, equivalent to more than a hundred 500ml bottles of water, or the daily drinking water consumption of ...
