Can you see it? That pale blue dot at center right? No, it isn’t a dead pixel or a dust mote on your monitor, it’s a picture of Earth from 4 billion miles. Beyond the orbit of Pluto, in fact. The photograph was taken in June of 1990 by the Voyager 1 spacecraft, launched from Earth thirteen years earlier. Pretty small isn’t it?
The photograph itself is one of several taken by Voyager 1, forming a mosaic of our solar system. It is the only such photograph in existence and is likely to be the only one for a long, long time. The red, green and yellow bands in the photograph are artifacts of the filters used to produce the color image and are caused by the sun just beyond the edge of the photo. A lens flare.
Everything you know, every person who has ever lived, every story that has ever been told, every hope and dream of every human, all the history of life as far as we know, it all comes from that tiny dot less than the size of a pixel in the image.
Think about it.
