The Pale Blue Dot

I'm sure you all have seen this photograph before and have heard or read this quote by Carl Sagan, and while I generally try to stay away from sharing cheesy quotes, I really think this one is anything but. It's good to be reminded.

"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

At 6 billion kilometers away, Earth appears as a pale blue dot. In 1990, Carl Sagan himself requested that NASA turn the Voyager 1 space probe around to take one last photo of Earth before traveling deeper into space. Image credit: NASA, Voyager 1.
