What We Do
- For over forty-five years, the Horwitz-DeRemer Planetarium has illuminated minds and fueled imaginations across Waukesha County. Operated by the School District of Waukesha and tucked within the scenic Retzer Nature Center, it brings the universe to life through engaging, curriculum-based programs that inspire students and visitors alike to look up, ask questions and explore the mysteries of the cosmos.
- The planetarium features a stunning 40-foot domed theater, where breathtaking, full-dome visuals bring the wonders of the universe to life for visitors of all ages. Each year, more than 31,000 curious minds – from students and families to lifelong learners – gather for over 650 immersive presentations that spark imagination and inspire discovery.
Where Your Money Goes
- Your support brings the wonders of the universe even closer. Every donation goes to installing Digistar 2025, a cutting-edge projection system that will fill the dome with brighter stars, sharper visuals and new ways to explore. With your help, Horwitz-DeRemer can create experiences that spark curiosity, build science skills, and inspire the next generation for years to come.
