Unfotunately the development of Celestia has stopped, and its official webpage is off-line. The program can still be downloaded from its source code repository, at SourceForge.

My contributions and resources

This page contains some contributions I have made for Celestia, a realistic simulation of the Universe. Celestia is free, it is open source, it is easily expandable, and it is available for all popular operating systems. Best of all, it is a beautiful and inspiring experience.
