Astronomy animations for Celestia
The purpose of the animations below is to illustrate the movement of the Earth and Moon around the Sun, and which consequences this have on day/night, seasons etc.
The animations are made in the free program Celestia. It makes it possible to move in space and time around in the universe and it has very good 3D effects. It is possible to manipulate the configuration files, so the universe can be configured to emphasize certain effects, which is useful in teaching. This is done in the animations below, which are scripts to the program.
There are three animations. They may be used for demonstration or by the pupils themselves. They work like small movies which may be paused.
The animations are made in two editions for Windows and one edition for Linux.
An installation guide is included in all versions. A Celestia version exists for MacOS, but the animations can not be run directly there.
A large collection of add-ons for Celestia (for example more detailed surface maps of the planets) and animations is available. There is a large package with Educational Activities for the universe more generally.
