Space image: Earth and its Moon as seen by Voyager 1
This picture of a crescent-shaped Earth and Moon -- the first of its kind ever taken by a spacecraft -- was recorded Sept. 18, 1977, by NASA's Voyager 2 when it was 7.25 million miles (11.66 million kilometers) from Earth.
Voyager 2 was launched on Aug. 20, 1977, 16 days before its twin, Voyager 1.
This photo was made from three images taken through color filters, then processed at NASA's Jet Propulsion Laboratory. Because the Earth is many times brighter than the moon, the moon was artificially brightened so that both bodies would show clearly in the prints.
