Pale Blue Dot "It has been said that astronomy is a humbling and character-building experience. There is perhaps no better demonstration of the folly of human conceits than this distant image of our tiny world. To me, it underscores our responsibility to deal more kindly with one another, and to preserve and cherish the pale blue dot, the only home we've ever known." Dr Carl Sagan
In 1991, Carl Sagan asked NASA to turn Voyager 1 around so he could see what Earth looked like from the farthest distance yet observed, about 4 billion miles. This is that photograph. And this is Earth.
