Planetarium Show – Weekend Activities

Visit Catalyst on 10th or 11th December for a chance to see this immersive family show

at 11:30am, 12.30pm, 2:00pm or 3.00pm

Join us in our new inflatable planetarium for an exciting 40 minute journey into space. Learn how to identify constellations and see how the stars appear to travel in the night sky before going on an epic ride in the hunt for alien life. Our show called ‘We are Aliens’, narrated by Rupert Grint, explores how our understanding of life on Earth guides the hunt for alien life!

Tickets for the show cost £1.95 per person in addition to the normal admission price but they are limited and can be booked on the website.

Please note: as this show takes place in our inflatable planetarium, visitors will be required to sit on the floor. Please let us know in advance if this will be a problem and we may be able to make accommodations. Visitors will also be asked to remove their shoes and enter the planetarium in socks.
