My favourite photo of you

I know it doesn't really show your smile, and you're a little bit hard to see, but if you're reading this in late 2013 you're quite likely to be in this photograph. That tiny blue dot is the planet earth from approximately 4 billion miles away, taken by Voyager 1 which only a few months ago crossed the boundary of our solar system into interstellar space. I was just reminded of this photograph in a TED lecture, and it is still mind-blowing.

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.
