Earthrise, photograph, by Bill Anders, 1968

The crew of Apollo 8 was armed with still and movie cameras to photograph the Moon; but the most enduring image of their mission is this photograph of their own home, planet Earth.

According to Anders, the astronauts saw the horizon vertically—not horizontally—with the lunar surface to the right.
