Astronomy

I recently have found a program (for windows/mac/linux) that can help you explore the solar system. It's called Celestia. It's a really great program and you can turn features on and off according to your systems needs. It can get pretty intense mapping out constellations and comet tails, so you have the option to turn these (and many other things) on and off. By the way, it's free.

Enjoy.
