   First ever drawings of the moon made by Galileo Galilei after observing it through his telescope in 1609.

   Galileo produced this extremely famous set of six watercolours of the Moon in its various phases "from life", as he observed the Earth's satellite through a telescope in the autumn of 1609. They represent the first realistic depiction of the Moon in history.

     #OTD in 1609, Galileo Galilei aimed his telescope at the Moon.

     While not being the first person to observe the Moon through a telescope (English mathematician Thomas Harriot had done it four months before but only saw a "strange spottednesse"), Galileo was the first to deduce the cause of the uneven waning as light occlusion from lunar mountains and craters. In his study, he also made topographical charts, estimating the heights of the mountains. via @wikipedia
