An exciting and stimulating way to learn more about the Universe in which we live.............

Here in our Planetarium we can show you the stars at any time - even during the daytime! We do this using a special machine called a star projector. It projects nearly 4 500 stars onto the domed ceiling of our star theatre. Here you will be able to view the night sky in comfort, without interference from clouds or bright lights.

With the star projector, slides, videos, DVDs, music, and a lively commentary, the planetarium allows us to explore the Universe by entering worlds beyond our own.

Inside The Planetarium

When you first come inside the star theatre, it will seem quite dark. We need the lights to be turned down low so that your eyes will get used to the dark. Settle yourself down into one of our comfortable seats. You may notice that they look like aircraft seats; that's because they used to be inside a Jumbo Jet!

After a few minutes, the lights will be turned off completely and, if you look up, you will see the stars of the night sky. we will also show you to Moon and planets, and point out some of the star patterns. in some presentations we take you on an imaginary journey to visit other places on the Earth, to show you what the stars look like from there.

An Educational Charity

The South Downs Planetarium project was born out of an awareness of the need to promote a greater public understanding of science in general, and astronomy in particular. It has been made possible by the many charitable donations the fund has received from individuals groups, and large organisations. We also have a team of dedicated Volunteers.

As an educational charity, the Planetarium needs YOUR help. why not join our Friends of the Planetarium Star Club, which has been formed in response to requests from visitors who wish to be more involved with this exciting project. Or consider joining the Planetarium's team of volunteers. No knowledge of astronomy is necessary. For further information on how you can help, call us on 01243 774400.
