We always have public shows during the academic year. Public shows also occur in the summer, depending on staff availability. The following information in addition to this list of our current show programs can help you plan your next public show visit.
Admission is $5 per person, cash only. No reservations are accepted, and admission is on a first-come, first-served basis. Please note that the seating capacity of the planetarium is 50 individuals. Doors will open 15 minutes before the show. No admittance after the show starts.
Should you have a question on the day of a public show, please reach out to 815-939-5307 for prompt assistance.
Note to ONU Students, Faculty, and Staff: During the academic year, on the Saturday evenings of public show weekends, there is an additional 9 PM show that is free to all ONU faculty, staff, and students. During the summer months, ONU faculty, staff, and students are admitted to all shows free of charge. Please bring your ONU ID to take advantage of these free shows.
