Pale blue dot
Apr. 13th, 2007 02:49 pmIn "An Inconvenient Truth" there were two images of the Earth as seen from space, that really struck me. I thought it was about time I changed my desktop wallpaper, so I had a look for them.
The first was The Blue Marble, showing the Earth fully lit. It was taken during the last manned mission to the moon, and is supposed to have influenced the 1970s enviromental movement. Showing the Earth's frailty, vulnerability, and isolation amid the expanse of space.
The second, less well known, image was the Pale Blue Dot. Taken by Voyager, from 6.4 billion kilometers away, the entire Earth takes up less than 1/8th of a pixel. Really puts things into perspective.
I also ran across another pale blue dot photo taken from a mere 1.5 billion kilometers away, but seen through Saturn's rings. I've got my new wallpaper now.
