Celestia Screenshots

Celestia is a very high quality and free 3D astronomy program which allows simulated flight through space and time.

Celestia may be tricky for younger students to get to grips with but it is also excellent software for educational demonstration purposes. The software is well documented and supported by many add-ons available for free download via the Motherlode Repository .

Versions are available for Windows, Mac/OSX and Linux operating systems.
