Planetarium Programs – Waukesha

The Horwitz DeRemer Planetarium at Retzer Nature Center offers immersive shows designed for the whole family. Shows run throughout fall and winter, with programs scheduled multiple times per week at various times. Each presentation costs just $5 per person and takes you on a journey through space and science—whether you're learning about dinosaurs, exploring distant planets, or discovering cosmic mysteries. The planetarium's state-of-the-art projection system lets you experience everything from flying through Saturn's rings to traveling at light speed to distant galaxies without ever leaving your seat. If you're planning a group visit, private show reservations are available for parties, scout groups, and community organizations. Tickets can be purchased online or up until showtime if seats remain available. The planetarium is fully wheelchair accessible, including the entrance, lobby, and theater.
