Admission is $3 for children and students under 18 and $5 for adults for the planetarium show. We do not accept checks or credit cards so please pay in cash.
In addition to the fulldome program The Hot and Energetic Universe there will also be a seasonal star show highlighting our current evening sky. Following the planetarium portion of the evening visitors will also have the opportunity view through the telescope. Some possible telescope targets are the Moon (if visible), Venus, Jupiter, and other assorted celestial hors d'oeuvres. Viewing through the telescope is always free, weather permitting (click on ClearSky Clock below).
Holcomb Observatory and Planetarium is located on the north end of the Butler University campus and can be reached by heading west on 46th Street from Meridian Street. Butler University Campus Map. Patrons can utilize our parking garage for a fee or park in the Hinkle Fieldhouse lot at no charge (provided no sports or special event is scheduled). For patron information there are three separate sets of steps to the telescope. Wheelchair accessibility is available in the Planetarium and Lobby area only. No elevator is available to the telescope viewing area.
If a weekend tour doesn’t fit your schedule consider scheduling a group tour for your group at another time.
