This image was taken, at Sagan’s suggestion, by Voyager 1 on February 14, 1990. As the spacecraft left our planetary neighborhood to the edges of our solar system, engineers turned it around for one last look at its home planet. Voyager 1 was about 6.4 billion kilometers (4 billion miles) away, when it captured this portrait of our world.
“We succeeded in taking that picture, and, if you look at it, you see a dot. That’s here. That’s home. That’s us. On it everyone you know, everyone you love, everyone you’ve ever heard of, every human being who ever was, lived out their lives. The aggregate of all our joys and sufferings, thousands of confident religions, ideologies and economic doctrines. Every hunter and forager, every hero and coward, every creator and destroyer of civilizations, every king and peasant, every young couple in love, every hopeful child, every mother and father, every 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.
The Earth is a very small stage in a vast cosmic arena. Think of the rivers of blood spilled by all those generals and emperors so that in glory and triumph they could become the momentary masters of a fraction of a dot. Think of the endless cruelties visited by the inhabitants of one corner of the dot on scarcely distinguishable inhabitants of some other corner of the dot. How frequent their misunderstandings, how eager they are to kill one another, how fervent their hatreds…
Our planet is a lonely speck in the great enveloping cosmic dark. In our obscurity — in all this vastness — there is no hint that help will come from elsewhere to save us from ourselves. It is up to us. It’s been said that astronomy is a humbling, and I might add, a character-building experience. To my mind, there is perhaps no better demonstration of the folly of human conceits than this distant image of our tiny world. To me, it underscores our responsibility to deal more kindly and compassionately with one another and to preserve and cherish this pale blue dot, the only home we’ve ever known.”
- Carl Sagan, commencement address delivered May 11, 1996.
This tribute is to hope and pray on behalf of the 2996 people who were killed on that fateful day. Many more have been killed before and after, all over this pale blue dot. Just like Voyager, we also need to turn and look back at man’s history on this fragile planet. Will we learn to cherish what we’ve got, or wipe ourselves out of existence?
