Earth from the Edge of the Solar System

My friend Lex tweeted this story from Discovery News.  It has this picture and a quote from Carl Sagan that is worth considering at the turn of this New Year.

"From this distant vantage point, the Earth might not seem of particular interest. But for us, it's different. Look again at that dot. [...] 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."
