Ever wish that you could take a ride on a space shuttle? Celestia is a 3D simulation that puts you in the passenger seat for a ride around the galaxy. Celestia doesn’t confine you to the surface of the Earth. You can travel throughout the solar system, to any of over 100,000 stars, or even beyond the galaxy.
Celestia features all of the major astronomical bodies, along with many star clusters. If you can’t find a particular celestial body, you can probably find it in the extensive add-on library. If you prefer sci-fi, you can download the Death Star from the Star Wars series and a laundry list of other fictional add-ons.
The application is available for Windows, Mac, and Linux and takes up 12MB of hard drive space. The universe is yours to explore with Celestia.
