Carl Sagan's series Cosmos: A Personal Voyage was broadcast on PBS in 1980. It was a huge success and now, in 2014, Cosmos is back in a new version.
In a lecture, after 1990's Voyager I aimed the spacecraft's camera back toward Earth, showing Earth as " . . . just a fuzzy dot amid a streak of sunlight." Sagan said, "That's here. That's home. That's us. On it, everyone you love, everyone you know, everyone you have ever heard of, every human being who ever was, lived out their lives . . . Every king and peasant, every young couple in love, every mother and father, hopeful child, inventor and explorer, every revered 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."
We are small in this vast universe. Remember to keep your life in perspective, knowing it is only a blip in the vastness time and space.
