The Crescent Earth

Some of the images in space are so familiar as to have become almost-instant visual cliches. Others most closely resemble abstract paintings, if anything at all. That they are actual celestial bodies seems nearly impossible to fathom. Looking at these pictures, it is easy to become lost in space.

Here is a picture of the crescent earth taken from the moon by the astronauts of the Apollo 11 mission in July 1969.
