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.


****The "Hudson Road Jam Band" will perform live in the Planetarium from 4:30 to 5:30 on Saturday October 22nd.  $2 donation suggested.  All proceeds benefit the Yahn Planetarium. PSB students free.  See astronomical wonders on the planetarium dome as the band plays some favorite jazz tunes.  Good for all ages!****


On Fridays around 30 minutes before sunset, join us for night sky observing at the Mehalso Observatories located behind the Otto Behrend Science building on the Behrend campus. Upcoming dates are September 2, 9, 16, 23 & 30. Please call Planetarium volunteer Sue at (814) 844-3805 or check back here for information or cancellations.
