A video tribute to Carl Sagan — and to Earth, our one and only home

… Upon seeing the above image of planet Earth, photographed from 4 billion miles away by Voyager 1, astronomer Carl Sagan was so moved that he wrote out his thoughts about the deeper meaning of this photograph. He later read his thoughts aloud, which are included in this short video tribute:

From this distant vantage point, the Earth might not seem of any particular interest. But for us, it’s different. 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. ~ Carl Sagan (1934-1996), Pale Blue Dot: A Vision of the Human Future in Space [1997:  Amazon].
