If you want to see something very, very beautiful you should point your browser to this page by the japanese space agency (do’h – broken link is fixed now) . It shows earthrise as seen from the Kaguya space probe that currently orbits the moon. That tiny blue marble that slowly climbs above the moons horizon, that’s us – the whole human habitat from a perspective that makes it look even more fragile.
This is a dumbed down version for the web – the full res video (Kaguya carries a HDTV camera) is apparently available only for teachers and educators on DVD. I hope some day this will be released to the general public.
