Lunar crater observations. 1882 artwork showing observations made of lunar craters. This is the landscape around the Tycho crater at sunset. Lunar craters are formed when asteroids or meteors impact the surface of the Moon. These collisions,which take place at high speeds,form a characteristic ring of crater walls,and a central peak. The mapping of the Moon with telescopes started with Galileo in 1610,and then developed further during the following centuries as telescopes improved. The observations,like those seen here,included recording changes in the shadows cast by high mountains and deep craters during the lunar day-night cycle | |
