At the request of astronomer Carl Sagan, NASA and JPL reawaken Voyager 1‘s camera for a last look back at Earth and its solar system, from a mind-boggling distance of 4,000,000,000 miles. The “last look” is actually composed of 60 separate photos, capturing most of the planets (with the exception of Mars and Mercury), including Earth – which takes up less than a single pixel in the image. Sagan points to the image as evidence of the fragility and uniqueness of Earth, and names his next book after the photo, “Pale Blue Dot”, also centered on that theme.
