The Pale Blue Dot is a photograph of Earth taken in 1990 by the Voyager 1 spacecraft from a distance of about 6 billion kilometers from Earth. In the photograph, Earth is shown as a tiny dot 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. He later used the image as the main title of his 1994 book, Pale Blue Dot: A Vision of the Human Future in Space.
