14 Feb 1990 Voyager 1 spacecraft turned to take photos of the solar system. Included was a now famous image of Earth, showing as a ‘pale blue dot’ in a grainy photo. In 1994, Carl Sagan presented this image to an audience at Cornell University and shared his reflections on the deeper meaning behind the idea of the Pale Blue Dot. This is just one film that illustrates his speech, using images from NASA.
