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 most realistic star projector, the ZEISS UNIVERSARIUM Mark IX, creates the largest artificial sky in the Western Hemisphere under our 80-foot dome. Relax, discover and explore with one of our Planetarium Educators during our interactive star 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.
Hubble 30th Anniversary Image
On April 24, 2020, NASA’s Hubble Space Telescope celebrated the 30th anniversary of its launch aboard Space Shuttle Discovery. The Saint Louis Science Center was selected as one of a limited number of locations across the nation to unveil the Hubble 30th anniversary photo to the public and is the only location in the state of Missouri.
One of only three in the United States, our ZEISS UNIVERSARIUM Mark IX is the world’s most realistic star projector. The Mark IX projects more than 9,000 stars and deep sky objects onto our 80-foot dome, creating a brilliant star field and the largest artificial sky in the Western Hemisphere.
Visitors can look up and see what the 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.
The exterior of the McDonnell Planetarium is illuminated nightly for all to enjoy. This illumination has helped raise awareness for charities and causes through special illumination requests.
