Pale Blue Dot

Abstract

On 14 February 1990, NASA's voyager-1 Spacecraft took a photograph of the Solar System dubbed the 'pale blue dot' what is interesting about this image ,taken 15 year ago at 6 billion kilometers way , in that the pale blue dot- that occupies not more than than a single pixel on this deep space image -is nothing but the planet that we all live in! NASA took this photograph on a request from Carl Sagan- well known atronomer & writer.
