The Voyager 1 spacecraft left Earth on the 5th September 1977 and since then it has visited the outermost planets of our solar system and continues to this day to fly into the unknown. In 1980 the renowned Carl Sagan, of Cosmos fame, suggested that spacecraft take one last photo of the Earth to help us understand our place in the universe. The photo was taken on 14th February 1990 from a distance of 6 billion kilometres from Earth.
In the image the Earth appears as a single light blue pixel against black space.
In a public lecture in 1994, Carl Sagan then shared the picture and his reflections on the deeper meaning behind the image. I now share his thoughts with you and I invite you to reflect on their meaning for you.
“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.
The Earth is a very small stage in a vast cosmic arena. Think of the endless cruelties visited by the inhabitants of one corner of this pixel on the scarcely distinguishable inhabitants of some other corner, how frequent their misunderstandings, how eager they are to kill one another, how fervent their hatreds. 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.
Our posturings, our imagined self-importance, the delusion that we have some privileged position in the Universe, are challenged by this point of pale light. 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.
The Earth is the only world known so far to harbor life. There is nowhere else, at least in the near future, to which our species could migrate. Visit, yes. Settle, not yet. Like it or not, for the moment the Earth is where we make our stand.
It has been said that astronomy is a humbling and character-building experience. 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 with one another, and to preserve and cherish the pale blue dot, the only home we’ve ever known.“
Carl Sagan’s thoughts were largely about perspective and how humankind sees ourselves and those around us.
I invite you to reflect on the this year and what it has held. The achievements, the failures, the joys and the sorrows. Seek perspective and take that into the next year..
