The mission of the planetarium is to report about the latest status of research. The scientific contributions will be preprocessed in a comprehensible way and opened to the public. The partially complex operations of the starry objects will be made visible in simulated demonstrations. As such, planetaria open the door to space for the layman. One of the most frequent visiting groups are classes. Since astronomy is part of the scientific education, special lectures are prepared for them. Children learn about the World they live in and will be incited to an interdisciplinary perception. The planetarium arouses interest in different issues from many fields of knowledge. It conveys the general education.
