Yahn Planetarium at Penn State Behrend

Water Festival program with kids in dome

Experience. Learn. Share.

For years, it’s been the place where thousands of young people and adults come to learn about the universe and worlds beyond our reach.

The Erie Planetarium served as a resource for the Erie community for more than fifty years, and it continues today as the Yahn Planetarium, now a part of Penn State Behrend. The planetarium is located in the School of Science complex on the Behrend campus.
