Tessmann Planetarium programming is designed to be interactive and engage people in the wonders of astronomy. Here, briefly, are what our shows offer:
"A Tour of the Solar System"
Dr. Eastmond, our Planetarium Director, presents an engaging introduction of physical concepts used in astronomy. Describing the sky on our thirty-three foot dome, participants are taken on a tour of our Solar System where we discover how rare the conditions are on our planet.

"Where are you?"
Lift off with Sheryl D. Johnson as she leads your students on an age specific adventure forming a backbone for their astronomy studies, reinforced with the latest images and information from the forefront of space science. Students will explore the current night sky and travel across the magnificent reality of our Solar System and Galaxy, discovering their own unique place and address in our universe.

"How far is up?"
Mr. Prescott introduces the scientific method while taking you on a journey from the center of the Earth to the edge of the Universe in search of the answer to a simple question, “How far is up?” You will participate in finding answers while you visit each of the planets of the Solar System, our Milky Way Galaxy and, ultimately, the limits of what we can see in our Universe.

As Plutarch once said, "The mind is not a vessel to be filled, but a fire to be ignited." At the Tessmann Planetarium, the right tools at the right time bring ideas and minds together. We strive to ignite minds with the wonder of astronomy... to be a Pathway to the Stars.
