McDonnell Planetarium


See the night sky in an entirely new way.

Our famous James S. McDonnell Planetarium is your gateway to the stars. Marvel as the world’s best opto-mechanical star projector, the ZEISS UNIVERSARIUM Model IX, simulates the most realistic night sky on our 24-meter dome. Relax, discover and explore with one of our Planetarium Educators during one of our interactive shows. It’s a stellar experience you won’t soon forget.



Boeing Space Station and Orthwein Starbay

The Boeing Space Station features two levels of exhibits that illustrate the future of space travel, and the Orthwein StarBay’s SBC Learning Center gives you a glimpse of what it’s like to live and work on the International Space Station. In the Crew Quarters, you’ll see how dwellers eat, exercise, sleep and dress in space, as well as how the crew meets medical needs and maintains the station’s internal and external environments.

Please note: All Boeing Space Station exhibit areas are closed during Planetarium Shows. Guests will be asked to gather in the Orthwein StarBay during this time.

Star Projector

The StarBay’s most amazing feature is the central open area dominated by our ZEISS UNIVERSARIUM Model IX. The UNIVERSARIUM projects more than 9,000 stars and deep sky objects onto a 24-meter dome, creating a brilliant star field.

Visitors can look up and see what the actual night sky would look like without the interference of weather, pollution or city lights.

Special features allow Planetarium staff to demonstrate eclipses, meteor showers and other celestial phenomena. The immensity and clarity of the view creates a sense of wonder that stimulates the imagination.



The StarBridge, located on the Planetarium’s highest level, focuses on the navigation and operations essential for life in space. Exhibits demonstrate the roles that communication, astronomical research, power and exploration play in maintaining a space station. Note that StarBridge is only accessible to visitors who have purchased star show tickets, and is closed during star shows.
