Our Gift Back

For 50 years, the Flandrau Science Center & Planetarium has stood as a center for scientific wonder and curiosity at the University of Arizona. Born from the vision of UA astronomers and with the assistance of Grace Flandrau, this establishment opened its doors in December 1975. Since then, Flandrau has brought the beauty of space and science to one of the "astronomy capitals of the world" to the Tucson community. From the Hector Vector Star Projector to today's Eos Foundation Planetarium Theater, Flandrau is proud to continue to bring inspiring experiences to all.
