Most of the world’s population lives in cities. The continuous presence and availability of artificial light has distorted our perception of the natural change of night and day.

The objective of the planetarium is to raise awareness for and improve comprehension of the movements of celestial bodies in the context of the universe. In order to give city dwellers, the opportunity to gain a better understanding of the movements of celestial bodies and the structure of the universe, the planetarium is situated in the centre of Hamburg in northern Germany.

The Planetarium should heighten the public’s perception of the earth in the universe and sharpen the eye in the everyday life for the celestial surrounding in the city.

The celestial theatre creates space for cultural as well as celestial events. Natural light and projection is combined in the celestial dome. The possibility to open an oculus allows to track the passage of the sun. The celestial dome provides space for concerts, stage plays or any imaginable cultural use. But its main purpose is to take us to the stars. The buildings inner structure is based on the solstices, celestial movements and city landmarks. In addition to technical possibilities to visualize the universe, extracts of the surrounding city and sky can been seen from small pictures boxes.

These pictures boxes guide the spectator’s view to interesting combinations of city-scapes and sun movements. To overcome daylight and light pollution in the city, a projection can be faded in as an overlay image of the clear night sky. Additional information about the luminaries can be viewed on the screen.

Modern technology allows city dwellers to observe the sky, regardless of light pollution. Little stargazer spheres transfer the visitor to any observation place of his or her choice. By using the stargazer spheres the spectator can individually head to an astronomical observatory, for example in Iceland, Alaska or Peru. He or she can even leave the earth behind to discover and experience the universe in a different scale and from a whole different point of view.
