The Sagan Series is an amazing project by Reid Gower in honor of the late Carl Sagan, the astronomer/cosmologist/astrophysicist. The project is simple, create short videos and add narration by Mr. Sagan (the narration of the above video is from his book Pale Blue Dot ). The outcome is just great.
Videos are being released every couple of weeks and you can keep track of them on The Sagan Series website. [Link]
