We will be offering FREE public shows this summer. When they are scheduled, they will be posted under EVENTS! If nothing is there, we are working on dates and times and will make an announcement in the future. 

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. Solstice Outreach is available for privately scheduled shows in their portable planetarium dome. The SciDome at The Works Museum is also open.
