UW-Stevens Point opens our shows to the public in the Allen F. Blocher Planetarium. The space consists of a 7.3m diameter dome that houses a Digistar Lite projector (installed in 2020). This immersive instructional tool is used for most astronomy courses at UWSP.

Planetarium shows provide impactful experiential learning experiences. Themes are selected to educate the public on topics ranging from cosmic cycles to planetary systems, telescopes, dark matter, the history of space exploration, and more.

Weekly public shows are presented through the academic year, typically on Sunday afternoon at 2:00pm. During the eight weeks of the summer, (end of May through the end of July), the Planetarium hosts regular public evening shows, twice per week. Check the calendar of events, which is updated regularly.

The planetarium and observatory facilities are operated and maintained by staff and student workers in the UW-Stevens Point Department of Physics and Astronomy. Our planetarium and observatory director is Dr. Sebastian Zamfir.
