The refurbished planetarium at the Swiss Museum of Transport is one of the few in the world that is able to project moving pictures on the inside of its 18-meter high dome.
This innovation aims to extend the Swiss museum's reputation for fascinating young and old visitors alike since it opened in 1969.
Within the dome, which has a projection area of 508 square meters, visitors are treated to breathtaking sights of the sky and the solar system, and discover principles and discoveries from the world of astronomy. A maximum of 230 visitors can enjoy the projections at a time.
The technology was designed in part by Swiss company Auviso. Auviso used special P-5 wash lights to illuminate the planetarium. These lights are equipped with an optimized cooling system and a control mechanism that allows for flicker-free operation. This is hugely important so as to not interfere with the astronomical projections.
