Just before leaving the Solar System in 1990, Voyager 1 was instructed to turn back towards Earth and take a picture. The resulting image, called the "Pale Blue Dot" is an iconic and moving piece of space photography.
Of the photo, Carl Sagan wrote: "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."
This design was inspired by both that image and the accompanying text: a pale blue dot, our home, suspended in a sunbeam. — Sarajea Martin
