Celestia - Explore the Universe

Celestia is a space simulator that lets you travel in our universe. You can explore the entire solar system and even go beyond our galaxy. Celestia doesn't just show you the sky, it lets you view the universe from any point you want. If you are familiar with Google Earth, it will be easy to use the program.

You can capture images and record videos, so you can use the program for your school projects. The program is also useful to learn information about planets, satellites and stars.

If Google Earth has Sketchup and 3D Warehouse, Celestia has Motherlode, a repository for 3D models and textures.

Celestia is open-source and it runs on Windows, Mac and Linux. After running the program for the first time, go to Help / Run Demo and select the full-screen mode.


  1. In related news, Larry Page talked to Anousheh Ansari, the first female private space explorer. She says:

    "Explore the boundaries. Try new things. Be free-thinkers and use your imaginations. Learn from your environment, your teachers, your books -- but then go beyond your knowledge. I always wanted to go to space, although I didn't wind up working for NASA. I detoured to different areas, but finally I found a way to make it happen."

  2. This is very very nice, thanks for sharing!

  3. I love Celestia. It really is the Google Earth of the Galaxy (and beyond).

    I could see Google buying them out someday....

  4. Truely an awesome program. I used it to replicate Solar Systems in Star Wars, how cool is that!

  5. a good thought to present humans visually of how infinitesimally small we are..
