Solar System Or Universe Display Software

Have you ever dreamt of being an astronaut? Or perhaps, you just want to know more about the different planets and galaxies. Celestia, which is free and open-source, lets you explore space in three dimensions. While it is available for multiple platforms, including Windows and Mac, we tested Celestia on a MacBook Pro running OS X Mavericks.

The user interface in Celestia is filled with buttons and options for just about everything, so it definitely comes with a lot of functionality. New users can run the demo to see the earth, the moon and so on. One problem we had in our test was fullscreen mode (press Command+F on Mac), which did not work very well. Fortunately, everything else seemed to work without problems.

We are not astronauts or astronomy experts, but Celestia seems like a fantastic application if you want to study galaxies or planets. Since it is free, we think it is definitely worth a try. Amazing what you can do with computers today, right?
