K Desktop Environment - Educational applications and Games

Learn and Discover with the KDE Educational applications Desktop Planetarium, KStars, provides an accurate graphical simulation of the night sky, from any location on Earth, at any date and time. It can control telescopes and has many tools for the amateur or professional astronomer. This new version now shows millions of stars, can predict conjunctions and has a Sky Calendar. If you start it for the first time, a welcome wizard will show. After choosing your location, you can click the "Download Extra Data..." to select additional star and image data to install. Millions of stars are available in the packages, as well as inline thumbnail images which show images of objects right on the sky. There are several interesting educational applications of this program as well. Pushing "CTRL-F" will bring up the find dialog. Type a name of a heavenly object to find it, like the moon. You might want to turn off "Toggle opaque ground" (most right button on the toolbar) to see the object if it is below the horizon. If you now choose "Equatorial coordinates" by hitting the space bar and set the time per second in the toolbar to 1 hour, watch. The moon moves - but, seen from the equitorial, not in a horizontal line! Why is that? The reason is that the earth spins, but not entirely as you might expect: there is a tilt and a wobble to the spin of the earth, and thus the observer moves up and down... Making science visible to children in such a way is a strong tool in the classroom, and this is a truly educational application. And it is not just for children, so be sure to have a look at this application if you are interested in astronomy!
