The ‘pale blue dot’ is a photograph of planet Earth taken from about six billion kilometers away. In this photograph, Earth is shown as a tiny dot against the vastness of space. 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’s words from 1994 help put our world in perspective. They make you feel so small. But also so big.

Who wouldn’t want to dedicate their efforts to making our pale blue dot a better place?
