Currently, public shows are scheduled most Friday evenings at 7:30 and last about an hour. The theater seats 60 people under a 35-foot dome. A special "star" projector is mounted in the center of the room which projects realistic images of the stars, planets, sun, and moon onto the ceiling for visitors to study and enjoy. During the academic year, 4-5 different shows are scheduled that address topics which cover the solar system, our galaxy of stars, and the universe of galaxies.

Current Show Information

12 Signs of the Zodiac

Show dates: Oct. 3, 10, 17 & 24; Nov. 7, 14 & 21

Of the 88 constellations in the night sky, there are 12 of them that are known by name to most people as the constellations of the Zodiac. Throughout the year, as our planet circles the sun, the sun appears to move through these constellations. Each constellation carries its own mythological stories. In our show, we will explore the ancient stories of heroes, gods and monsters as well as the astronomical highlights to be found with telescopes, binoculars and the unaided eye.

Recorded information about our current show is available by calling the Planetarium at 503.399.5200.

Adults: $5
