EARTH AND SPACE
This site is a very large collection of images, and short films, of the objects in the solar system. There is also a lot of text information on the objects.
This has, amongst other things, three good detailed animations on the life of small and large stars.
Build your own star, and then see how it develops. Clever.
This is the Powers Of Ten sequence, which starts at the size of the Universe, and then gradually zooms in. It is great; it will work automatically, while you talk, or just watch!
This shows a huge variety of the actual satellites orbiting the Earth, in all their different orbits - beautiful. (Note: If there are no satellites, try selecting 'Satellite', 'Select', and then 'View All ')
Set your own 'satellite' going with your choice of velocity, and see what happens.
The familiar link between terrestrial projectiles and satellite orbits as v increases, is well shown by this one - with the projectile setting off faster and faster from the high tower at the north pole.

Surf the night sky, with Google.
