Welcome to Tarleton’s Planetarium

About the Planetarium

Aerial view of Lamar Johanson Science Building

Located under the iconic copper dome of the Lamar Johanson Science Building on the Stephenville campus, the 86-seat, College of Science & Technology planetarium provides a spectacular full-dome immersive experience. The Digistar projection system, combined with 5.1 Dolby surround sound, brings the wonders of astronomy down to earth for our visitors. 

Additional technology allows the 86-seat facility to serve as a lecture hall for film studies, a performance venue for guest speakers and musicians, as well as a cool, comfortable theater for current students to watch classic and contemporary motion pictures.

The planetarium hosts special digital presentations for the public throughout the year, including children’s matinees and special holiday presentations for the entire family.

Supporting our community’s school-aged children through science outreach and enrichment is a key part of the planetariums mission within the College of Science & Technology. We encourage public, private and home-school teachers to contact the planetarium office to check on opportunities to visit and learn in this wonderful facility.

 Join us soon at the Tarleton Planetarium.


“The Mystery of the Christmas Star,” will run through Dec. 20. It investigates possible dates for the birth of Christ and examines recorded sightings of significant astronomical events at the time. Planetarium visitors will see how signs in the sky could have been remarkable enough to cause the wise men to travel across the desert to Bethlehem, likely from the southern tip of the Arabian Peninsula.
