Each year, the planetarium presents over 650 immersive shows to more than 31,000 visitors of all ages. The facility features a 40-foot domed theater equipped with 94 seats, a Digistar 6 digital projection system, and a hearing loop system with AV and FM hearing assistance. To make programming accessible to all, the planetarium offers Spanish-language shows and captioning in both English and Spanish.
