The Planetarium Show

Visit Catalyst on 16th or 17th March for a chance to see this immersive family show

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

Join us in our inflatable planetarium for an exciting 45 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.
Pay once for general admission though and we will convert that into an annual pass so you can come back and visit as many times as you like over the next 12 months!

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.
