Experience Space like Never Before

The Planetarium is an instrumental learning environment within the Science Community Center. Students studying astronomy utilize the planetarium as a learning laboratory traveling from planet to planet within our solar system and beyond. Such a tool allows one to experience the universe in a way far superior to what images in a textbook can convey. Other classes, such as Earth Science, Geology, Physics, Life Sciences, and the Humanities also visit the planetarium to bring a context to their learning that goes far beyond the classroom.

The planetarium itself consists of a Zeiss Skymaster ZKP-4 LED/fiber-optic star projector coupled with the Zeiss Velvet Projection System. Together, these top-of-the-line projection instruments display unparalleled images of the night sky and full-dome planetarium films onto a 40-foot suspended dome ceiling for an audience of up to 100 people.
