Great Minds, Great Words: Carl Sagan - Pale Blue Dot. A Vision of Human Future in Space. The Pale Blue Dot is a photograph of planet Earth taken in 1990 by Voyager 1 from a record distance, showing it against the vastness of space. By request of Carl Sagan, NASA commanded the Voyager 1 spacecraft, having completed its primary mission and now leaving the solar system, to turn its camera around and to take a photograph of Earth. It was subsequently used by Sagan as the title of his 1994 book of the same name.

Sagan had pushed for Voyager to take a photo of the Earth when its vantage point reached the edge of the solar system. On February 14, 1990, having completed its primary mission, NASA commanded the spacecraft to turn around to photograph the planets of the Solar System. Between February 14, 1990 and June 6, 1990, one image Voyager returned was of Earth, showing up as a "pale blue dot" in the grainy photo. Carl Sagan gives the distance as 3.7 billion miles (6 billion kilometres) in his book. • *******en.wikipedia****/wiki/Pale_Blu... --- Carl Edward Sagan, Ph.D. (1934-1996) was an American astronomer, astrochemist, author, and highly successful popularizer of astronomy, astrophysics and other natural sciences. He pioneered exobiology and promoted the Search for Extra-Terrestrial Intelligence (SETI). He is world-famous for writing popular science books and for co-writing and presenting the award-winning 1980 television series "Cosmos: A Personal Voyage", which has been seen by more than 600 million people in over 60 countries, making it the most widely watched PBS program in history. A book to accompany the program was also published. He also wrote the novel "Contact", the basis for the 1997 Robert Zemecki's film of the same name starring Jodie Foster. During his lifetime, Sagan published more than 600 scientific papers and popular articles and was author, co-author, or editor of more than 20 books. In his works, he frequently advocated skeptical inquiry, secular humanism, and the scientific method. • *******www.carlsagan**** .
