Testimonials on Tripadvisor.


Absolutely fantastic.

Everyone here works really hard, it’s was such an interesting show, the dome is magnificent lit up and you really feel you have been transported into space! Comfy seats and we will def be returning with all the family, young and old.

Absolutely something for everyone. Nice to do something different

Advance booking is recommended as shows do sell-out.


Well worth a visit.

Very interesting afternoon. Wasn’t what I initially expected but thoroughly enjoyed it, even learned a bit too. Very friendly and helpful staff. Even more satisfying, my 10 year old son and 7 year old daughter were gripped. I’ve never seen them so quiet for such a long time



I have been here several times now for various shows over the years and I never stop telling my friends about it and how they must go even offering to book tickets for them to go and reminding them when their show date is due so they don't miss it.

It's an excellent venue, the building is great, loads of artefacts and masses to look at, the main Lecturer Dr John Mason is just amazing, so full of energy and life and passion.

I cannot say enough what a wonderful place this is to visit and I shall continue to spread the word

Testimonials on Facebook.

We are so lucky to have this marvellous facility. There is always a warm welcome and the presentations are jaw-droppingly good; interesting, informative and delivered in an easy to understand, fun way by Dr John Mason and all the supporting team. All ages and all levels of experience will get something from it. Very highly recommended.

Sir Patrick Moore will be smiling down proudly.

Wendy Adams Evans

49 of us from the W.I. enjoyed a very interesting and informative morning here. It is run by volunteers as a charity and they cater for Junior school groups, around 1100 children visit every year.

The speaker was enthusiastic and his passion for all things space was clear as he took us through the planets and the more visible stars and how to identify some constellations in a northern Hemisphere.

You don’t have to go in a group but you do need to check up when it is open and what ‘talk’ is on. Well worth a visit.

Brilliant have taken my year 7's here from The Regis School. Brilliant kids loved it, really inspired them and they loved the topic of space from this visit. Thank you for a super time.
