In the huge dome of the planetarium young scientists and interested adults see an artificial sky with 360° Fulldome projection technique and experience a very varied programme: cool laser shows, speeches on astronomy, multimedia events, children's programmes, readings and much more - no matter what the weather is like outside!

With clear skies and good weather conditions, interested stargazers can also discover the sky with their own eyes. On the hilltop of the Insulaner is the Wilhelm-Foerster-Observatory and through their big telescopes you can see the big planets with their moons, the craters and mountain ranges of the Earth's moon, the sunspots and a large number of stars, galaxies and nebulas.
