The planetarium is open and we are taking requests for private shows in December 2023 and Spring 2024. We do not do shows near the winter holidays due to staff limitations. As the outreach arm of the Department of Astronomy, we are not a full-fledged or staffed science center. We do our best to meet all requests. We offer public shows based on staffing availability. The Planetarium at COSI is open for public programs.
