16 - 31 October 2021

This October Half Term join our Discovery team to learn more about how the Webb Telescope will fundamentally alter our understanding of the universe.


The Webb Telescope will be the largest, most powerful and complex space telescope ever built and launched into space. It will help astronomers to compare the faintest, earliest galaxies to today’s grand spirals and ellipticals, helping us to understand how galaxies assemble over billions of years.

Webb will be the largest telescope ever placed in space. It includes a huge mirror, so big it has to fold to fit inside the rocket. The telescope’s tennis court sized sun shield, will be folded like origami for launch, and will unfold like a “Transformer” in space.

With unprecedented infrared sensitivity, it will peer back in time over 13.5 billion years to see the first galaxies born after the Big Bang. It is so sensitive; it could detect the heat signature of a bumblebee at the distance of the moon.

To ensure the safety of visitors and staff day tickets are significantly reduced.

Booking in advance is ESSENTIAL (including Annual Pass holders).

Space Telescopes

Join our discovery presenters to find out more about the amazing mirrors that help Webb to look farther back in time than any other telescope. Through live demonstration understand the history of how space telescopes work and some of the instruments that are part of these incredible space crafts.

11:00, 12:00, 14:00 and 15:00

Make a Webb Mirror

For the Webb Telescope to fit into a rocket, it must fold up. Whether it is the primary mirror or the sunshield, many parts of Webb are designed to deploy or unfold once in space. Join us to create your own Webb primary mirror and discover the elegant engineering and artistic inspiration behind the telescope.


Spectacular Spectrum

The Webb telescope will be using near infrared light to look at galaxies and peer back in the history of the Universe. Join the discovery team to explore different types of light from UV, IR and visible light.


Planetarium Show

Included in your first visit is an award-winning planetarium show.
Annual Pass holders may be able to purchase a show on the day, but this is subject to availability, as we have significantly reduced capacity in the theatre.

We Are Astronomers

Do you know what an astronomer does?
Today’s astronomer is not the lone observer of past centuries. We Are Astronomers reveals the global collaboration, technology and dedication required to answer the unresolved questions of the Universe. We Are Astronomers, narrated by David Tennant, is an exciting 360° fulldome digital planetarium show with input from UK astronomers.
