"I was an experimenter around the Voyager 1 and 2 spacecraft. And after they swept by the Jupiter, Saturn, Uranus and Neptune systems, it was possible to do something I had wanted to do from the beginning, and that is to turn the cameras on one of these spacecraft back to photograph the planet from which it had come. And clearly, there would not be much scientific data from this because we were so far away that the earth was just a point - a pale blue dot.
But when we took the picture, there was something about it that seemed to me so - poignant; vulnerable, tiny. And if we had photographed it from a much further distance, it would have been gone, lost against the backdrop of distant stars. And to me, it - I thought there - that's us. That's our world. That's all of us - everybody you know, everybody you love. Everybody you ever heard of lived out their lives there, on a mote of dust in a sunbeam.
And it spoke to me about the need for us to care for one another, and also, to preserve the pale blue dot, which is the only home we've ever known. And it underscored the tininess, the comparative insignificance of our world and ourselves."
