Ready for a space adventure?

The Planetarium is epic. A massive screen is all around you to make you feel like you're flying through space. Look over there – there's stars and planets and action everywhere!

This is where you can see a fantastic fulldome film show or an out-of-this-world live show. Watch fun characters head off on exciting adventures in a subtitled film show. Woosh! Or in a live show, you can listen to our space hero Inspirers telling amazing stories about the Solar System. Whatever you pick, you'll find out fantastic space facts. Learn all about the planets up above us. If you want to ask a question, call it out. If you can't believe your eyes, tell us. Our shows change throughout the year so check out what's on when you visit.

Are you ready for the space journey you'll never forget? Let's do this!

Accessibility info

Accessibility information for the Planetarium

The Planetarium is accessible so everyone can have a special experience here. Every show is relaxed with quiet and calm presentations. It's not super dark and you can move around, go out and come back in if you like.

If you have a wheelchair, we have spaces for you to sit with seats for your family and friends. The stairs have lights to make them easy to see. We've also got super 3D printed models and NASA's official tactile books. You can use them when you watch a show. Our fulldome film shows have subtitles and there's an induction loop. Need ear defenders? We can help with those.

We even have special British Sign Language days for shows in the Planetarium, Science Live and Science Theatre. Just ask and we'll tell you when they are so you don't miss them.
