the hemispheric-shaped planetarium primarily presents films dealing with astronomy. until 2007, the theatre was called the verne theatre, and it ran super films and multimedia programmes made with special slide projectors that took advantage of the entire 500 m2 surface of the hemispheric screen. at the end of 2007, the theatre was entirely renovated, and reopened on 26 december 2007 as one of europe’s most modern digital planetariums. there are altogether 135 seats in heureka’s planetarium.
