The Zeiss Model II Star Projector, used from 1939 to 1991 at the Buhl Planetarium, is an iconic feature of our SpacePlace exhibit gallery. The projector’s complex clockwork mechanisms allowed it to accurately display the stars as they would appear from any location on Earth at any point in time.
In use at the Buhl Planetarium from 1939 until Carnegie Science Center opened in 1991.
During World War II, Air Corps pilots trained using the Zeiss Model II Projector.
This exhibition was made possible by the Buhl Foundation.
In addition to the projector, this exhibit features several interactive experiences, including:
A “time machine” that lets visitors select any year from 1939 to the present and explore significant events in astronomy during that year.
