Flandrau Today
Flandrau today is a dynamic center for science learning, community connection, and immersive exploration. Recently named the number four planetarium in the country by USA Today readers, Flandrau continues to shine as one of the region’s most beloved destinations for discovering the wonders of space and science.
Inside the Eos Foundation Planetarium Theater, visitors experience stunning fulldome shows powered by advanced projection technology and powerful surround sound. These same tools also support innovative teaching for University of Arizona students, who use the dome as a classroom to explore astronomy in a way few universities can offer.
On the exhibit floor, the new Universe of Science exhibit gives guests a hands-on way to connect with everything from astronomy to monsoons to the cutting-edge research happening across campus. Interactive displays, digital features, and large-scale models invite visitors to see themselves in the world of science.
Flandrau remains deeply committed to access and equity. Through free field trip programming for Title I schools, thousands of young learners experience the excitement of astronomy and STEM each year, many stepping into a planetarium for the first time.
Each year, Flandrau welcomes tens of thousands of visitors and serves as a gathering place for major astronomical events like eclipses, as well as for science lectures, laser light shows, and community programs that bring people together under the stars.
As Flandrau continues to grow with new exhibits and experiences, it remains a gateway to discovery and a place where curiosity, community, and the Wildcat spirit of exploration continue to thrive.
Fifty Years of Flandrau
Flandrau Science Center & Planetarium got its start with a 1972 bequest from the estate of Grace H. Flandrau, noted author and frequent winter visitor to Tucson. The University decided to use the generous gift to fund a facility that would increase public understanding and appreciation of science.
Originally known as The Grace H. Flandrau Planetarium, the facility was part of the University of Arizona's Department of Astronomy. Its location on campus, near the Astronomy Department, Optical Sciences Center, Lunar and Planetary Laboratory and historic Steward Observatory, reflects its continuing connections to the research community.
The Planetarium was designed by Tucson architectural firm Blanton and Company and opened its doors to the public in 1975.
