Ohio State is in the process of revising websites and program materials to accurately reflect compliance with the law. While this work occurs, language referencing protected class status or other activities prohibited by Ohio Senate Bill 1 may still appear in some places. However, all programs and activities are being administered in compliance with federal and state law.

The planetarium projectors have been fixed. We are accommodating some privately scheduled shows and events. We will be offering FREE public shows this Spring, and 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.
