This is one of the most wondrous and moving paeans to space exploration I have ever seen. The words of Sagan are magnificent, of course. And the effects are stunning, photo-realistic and very compelling.
But take a moment and let this sink in: Nearly every location depicted in this video is real. These aren't just fanciful places made up in the head of a special effect artist; those are worlds in our solar system that actually exist. And many were based on images taken through telescopes, or probes that have physically visited these distant locales.
Sunset on Mars. The weird ridge wrapped around Saturn's moon Iapetus. The ice fields of Jupiter's moon Europa. Even those cliff divers? Yup: that's Uranus's moon Miranda, with the highest cliffs known in the solar system.
