The visit starts in the planetarium. Here you step into the wonderful world of astronomy. On an 84m² domed screen you watch the desired fulldome show from one of the 45 reclining chairs. This can be about the solar system, the planets, the universe, black holes and exoplanets. Following the film screening, we discover the magnificent starry sky and travel to other planets. You will undertake a journey to the darkest places on earth where you can observe more than 7000 stars. Why are the days longer in summer than in winter? Or how about the Midnight Sun and the Pole Star?

Exhibition space

In the interactive exhibition at Cozmix you will find answers to many questions. You'll find a wealth of information about the origin and life cycle of stars and, of course, about our own solar system. How are stars and galaxies grouped together? Is the universe really expanding and is there an end to our universe? What does a nebula look like? And how did we find out about all this?

If the planetarium is the beating heart of Cozmix, the telescopes in the tower are the highly sensitive eyes of the visitor center. The two large telescopes in the dome bring countless objects in the starry sky into excellent focus. A visit to the observatory would not be complete if you did not visit our telescopes. Even in case of poor weather, we have an alternative.




Groups can opt to add one or more workshops to their visit in addition to (or instead of) the basic visit and thus put together their own program. View the different workshops here.
