Pale Blue Dot
Another fantastic image from Cassini, putting our tiny world into perspective. Once again, I am reminded of the the words of the great Carl Sagan, and his "pale blue dot" speech which never fails to choke me up and bring tears to my eyes, every time I hear it.
For me, the moment of clarity is when I hear the one sentence from that speech which is the crux of the whole thing: "There is perhaps no better demonstration of the folly of human conceits than this distant image of our tiny world."
