I have created a new HD dramatic video trailer for use by Earth Science and Astronomy teachers around the world. It is called "Introduction to the Solar System". Several of the scenes in it are video captured using Celestia.
You can see it here: http://www.youtube.com/watch?v=svvwv5oAf4I&list=UUWxJwdNjOFOUvKAhsYo41lg&index=7
View it in full screen with your speakers turned up. The music is dramatic. Enjoy
