Celestia

hether you love astronomy or just want to learn more about the universe in a way that's different and interactive, Celestia makes for an excellent tool. Celestia gives access to hundreds of celestial bodies flung in the farthest corners of the universe. The navigation panel takes you to these places in a quick and easy way – so sit back, relax, and calmly check out the cosmos during your trip. Stars, constellations, nebulas, galaxies, comets, planets, and satellites are just part of what you can visit with Celestia. You can also trace the orbit around a celestial body or follow it through space. Also, just like in a documentary about the universe, Celestia lets you create and run scripts in order to follow a preset path through space. Every place you visit will be explained by an identifying label.
