Pale Blue Dot
The Pale Blue Dot is a photograph of planet Earth taken in 1990 by the Voyager 1 spaceprobe from a record distance of about kilometers from Earth, as part of the solar system Family Portrait series of images. In the photograph, Earth is shown as a fraction of a pixel against the vastness of space. The Voyager 1 spacecraft, which had completed its primary mission and was leaving the Solar System, was commanded by NASA to turn its camera around and to take a photograph of Earth across a great expanse of space, at the request of Carl Sagan.The above text is a snippet from Wikipedia: Pale Blue Dot
