Welcome to the Astrium Planetarium

The Astrium Planetarium at Winchester Science Centre is the UK's largest capacity planetarium.

"The planetarium show is amazing; I would say life-changing for some people... " Tripadvisor comment

The enormous domed screen completely surrounds the audience, placing you right in the action. Relax back into a seat and get sucked into a black hole, fly through the solar system or even explore the human body. A fantastic shared experience that will have children reaching their hands up to touch the stars as they fly by.

 Planetarium 01

Winchester Science Centre would like to thank SEEDA for funding the installation of this world-class facility and Astrium for generous sponsorship supporting its ongoing use.

How does it work?

Planetarium technology has advanced beyond recognition in recent years. It is not just stars; now viewers can see full-screen video using a state-of-the-art digital projection system. The cinema-grade surround sound system adds to the feeling of total immersion. There is simply nothing like it.

Winchester Science Centre’s system, designed and installed by Global Immersion, relies on a bank of seven computers running six projectors arranged around the audience (hidden behind holes). There is no central projector to disrupt your view. You can see one projector clearly at the back above the desk (the large black one).

Each projector creates one part of the image. The projections fade out at the edges to blend into the neighbouring sections to give a 'seamless' appearance. The projectors are reguarly calibrated to ensure brightness/contrast/colour matching across the entire dome.

In addition to playing 360o fulldome films, UniViewTM software by SCISS allows presenters to fly visitors through a virtual universe based on actual scientific data. Each star and galaxy is accurately plotted and planets are 'wrapped' in real images from spacecraft wherever possible. Nothing is pre-recorded, everything is rendered in real-time, making each show unique.

The presenter can set time and date to show objects in the correct locations/orientations for the time of the show and then pilot a seamless flight from our Earth around the solar system and out to the edge of the visible universe, bringing in labels or markers as required, or speeding up or slowing down time to demonstrate the movement of objects.

Check out the show schedule for the short-term confirmed schedule. If planning further ahead, this is how the schedule is likely to look:

School days:

The planetarium is usually busy with school groups until after lunchtime.

There is usually one public show at 2:30pm and one at 3:30pm (times may vary).

Rarely, a school day will have no scheduled shows. See the events calendar for known dates. These will be due to special/private events or to allow maintenance of the facility.


Shows run every weekend and school holiday except at Christmas (24-26 Dec) when Winchester Science Centre is closed. 

There are usually at least four different shows on the schedule to suit all ages.

Showtimes are usually 10:40am, 11:30am, 12:30pm, 1:30pm, 2:30pm, 3:30pm and 4:30pm. Additional shows may be scheduled in busy holiday periods or on days with extended opening hours.

Occasionally, one or two showings may be replaced by other special events. These dates are advertised as early as possible in the events calendar

Saturday Night LIVE special, presenter-led shows, run for an hour including Q&A. 360o fulldome planetarium films are run these same evenings.

Bringing children:

Children under 16yrs: must be accompanied by an adult at all times.

Children under 5yrs: the planetarium is not recommended for children under 5yrs due to darkness and powerful images/sounds. The experience can be rather overwhelming for some, or for others so exciting that the children can't help but call out! However, it can be difficult to split family groups so entry is not restricted. Be aware that you will be asked to leave if your child is disruptive. You might prefer to come to one of our  Chatterbox showings where chatting and calling out is allowed.


Children under 3yrs: free entry if you are happy for them to sit on your lap. However, please think carefully before bringing such young children in as they will need to sit still and quietly through the show which is clearly not natural behaviour for most toddlers!



 Planetarium 02



There are six spaces for wheelchair users at the back with great views of the screen. Mobility scooters can be driven straight in through the main entrance. Adjacent seats are available for family and friends, or for anyone else preferring same-level access.


The seating is raked, with wide and broad steps down to the front. Seats at the back of the planetarium sit almost upright, while those at the front lean back. They are all padded with head-rests and flip-up seats and are generally considered very comfortable. Some seats (not level access) have space for a single leg to be extended at an angle, please let us know when booking if you would like us to reserve one of these for you.


Planetarium seats are 51cm wide, constricted to 46.5cm by the arm-rests. We can provide padded office-style chairs (40cm wide, no arm-rests) in the wheelchair spaces on request.




The planetarium has a hearing loop, requiring the T setting. 


We regret written scripts cannot be provided for public shows; it would be too dark to read them inside the planetarium and torches would be very distracting for other audience members. If you are a group booking a private show, please ask and we will explain the level of disruption, how best to mitigate this and whether scripts are available for your chosen show.

Subtitled/BSL shows available on demand to groups and schools:

  • Astronaut can be screened with summarised subtitles projected over the show
  • Flight Through the Universe can be run as an adapted version with subtitles and/or BSL
  • We can also accomodate (or arrange) sign-language interpreters on request: please ask when booking. 




There are regular Chatterbox shows where audience members are allowed to chat or call out during the show. See planetarium schedule for dates and times.




Download this social story (.pdf) for autistic school visitors, which includes images of the exhibition and planetarium that may also be of interest to public visitors (although please be aware public visitors use a different entrance to schools). You may also like to use our online planetarium tour to explore the space before your visit.


Epilepsy / other


The shows "Astronaut" and "We are Astronomers" have scenes containing flashing lights which may affect those with light-sensitive epilepsy. 


If you have a balance/neurological condition (eg vertigo, MS), please be warned that motion on the giant screen may make you feel disorientated and uncomfortable.


If you would like to see the theatre space in advance to orient yourself or others then this can be done online in our planetarium tour.


If there's any other information you would like to see in this section, please let us know.

The future:

Winchester Science Centre are busy planning more events to cater for different audiences in the planetarium. Please sign up for the newsletter to receive the most up to date information by emailing Marketing Officer Lucy Gray.

The Astrium Planetarium is a fantastic resource for all of Hampshire and, as an immersive environment, can be used for music, theatre and many other events. It will also continue to be used as an auditorium for science shows and corporate events, as the seats can be adjusted to sit upright.

If you are interested in being involved with the planetarium, for instance by volunteering to help at events, please contact the Head of Planetarium, Dr Jenny Shipway.
