To Space & Back takes audiences on an incredible journey from the far reaches of our known universe to our own planet.
Watch the Show
The planetarium is open and we are taking requests for private shows. We are an outreach arm of the Department of Astronomy, not a full-fledged 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.
