In 1609, Galileo Galilei drew one of the first telescopic drawings of the Moon in his book and noted that it was not smooth but had mountains and craters. Later in the 17th century, Giovanni Battista Riccioli and Francesco Maria Grimaldi drew a map of the Moon and gave many craters the names they still have today.

Face on Moon South Pole Face on Moon South Pole The Face on Moon South Pole is a region on the Moon (81.9° south latitude and 39.27° east longitude) that was detected automatically in an image from the Lunar Reconnaissance Orbiter by a computer system using face recognition technologies, as a result of a project that was part of the International Space App Challenge 2013 Tokyo. It is composed of craters and shadows on the moon's surface that, together, form an image resembling a face. The "Face on Mars" is a better known example. Human brains have the ability to detect ambiguous images displayed upon
