Pale Blue Dot

"The Earth is a very small stage in a vast cosmic arena."

Carl Sagan requested that NASA take this final picture in 1990 as the Voyager Spacecraft, which had completed it's final mission, was leaving the Solar System. The Pale Blue Dot, along with Carl's narration, gives us a glimpse into the potential for human beings to wake up to the insanity that permeates much of their current existence. Here's to hoping that in the future we can all carry this perspective with us longer than the few minutes it takes to watch this video.
"In all this vastness, there is no hint that help will come from elsewhere, to save us from ourselves."
If you're interested in more of Carl Sagan's thoughts, a good book to pick up is:

Or you can watch his awesome series Cosmos which is the best explanation of space on this planet.
