When the Voyager 1 probe was 3.7 billion miles from Earth, Carl Sagan made a request.
He asked NASA to turn it around to snap a quick photograph. The result was a faint image of Earth surrounded by the vastness of space. The late astronomer would then use this picture to share his own reflections on what it meant and why it was important for us to capture.
“Look again at that dot. That’s here. That’s home. That’s us. On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives. The aggregate of our joy and suffering, thousands of confident religions, ideologies, and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer of civilization, every king and peasant, every young couple in love, every mother and father, hopeful child, inventor and explorer, every teacher of morals, every corrupt politician, every “superstar,” every “supreme leader,” every saint and sinner in the history of our species lived there–on a mote of dust suspended in a sunbeam.
