Planetarium Programs – Waukesha

Head to the Horwitz DeRemer Planetarium at Retzer Nature Center this fall for a variety of immersive shows. Each presentation takes you on a journey through space and the cosmos—you might explore distant galaxies, visit other planets, or learn about celestial phenomena, all from your seat in the theater. The planetarium features a high-definition laser projection system that brings these experiences to life on a grand scale. Admission is $5 per person, and tickets can be purchased online or at the door if seats are available. The planetarium offers different shows throughout the season, many designed with specific age groups in mind. Whether your kids are interested in dinosaurs, space mysteries, or holiday-themed adventures, there's something on the schedule. Group reservations are also welcome for scouts, birthday parties, and other gatherings. The venue is fully wheelchair accessible, including the entrance, lobby, and theater. For more details or to book a private group showing, call 262-970-4139. After the show, you can explore the Retzer Nature Center grounds to extend your visit.
