Pale Blue Dot
It is 20th anniversary of this photo taken by Voyager 1 and famously named by Carl Sagan as “Pale Blue Dot”. Read the full NPR story here. I really liked Sagan’s description of the photo.
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.
This comes from his book with the same name: Pale Blue Dot: A Vision of the Human Future in Space
In the last 20 years, Voyager 1 and 2, traveling at about 35,000 miles per hour, have moved farther away (at about 10 billion miles or 16 billion km currently) from Earth out on the fringes of our Solar system. If they look back and take a picture now, Earth will not even be seen in it.
