When the lights go down, the ceiling goes too.

The house lights fade over ninety seconds, the seats lean back thirty degrees, and then there is only sky: nine thousand stars, each one placed where it really stands above the city tonight.

Outward

Our flagship show runs fifty-two minutes and makes five stops, each one further from home than the last. The astronomer at the console decides how long we stay.

  1. A person standing on a grassy hill under a starry night sky
    01

    Tonight’s sky

    Straight above the roof

    The sky over the city at ten tonight with every streetlight switched off: which planets are up and where to find them on the walk home.

  2. Close view of craters on the surface of the Moon
    02

    The Moon

    1.3 light-seconds away

    We drop low over the craters at the edge of the dark side, where shadows run for miles and the ground is older than any rock on Earth.

  3. The Sun seen from space with a flare leaving its edge
    03

    The Sun

    8 light-minutes away

    Close enough to watch a flare lift off the surface, in the colours a space telescope sees and with a sound you will feel in the seat.

  4. The band of the Milky Way rising over a dark mountain ridge
    04

    The Milky Way

    100,000 light-years across

    We leave the Sun behind and turn to look back at our galaxy from the outside, a slow spiral with us somewhere in an outer arm.

  5. Two galaxies colliding in a cloud of blue and pink light
    05

    First galaxies

    13 billion years back

    The last stop is as far as light allows: galaxies caught colliding, and behind them the first ones that ever shone.

A ceiling that isn’t there

The dome is twenty-three metres across and tilted fifteen degrees toward the horizon, so the sky sits in front of you as well as overhead.

Two hundred and twelve seats lean back thirty degrees. Two laser projectors stitch the picture edge to edge, and the star projector in the middle of the room draws nine thousand stars as sharp points of light, never pixels.

This season’s shows

Five shows, all narrated live. Doors open twenty minutes before the start, and once the lights are down we keep them down.

Adults £14, under-16s £9, a family of four £40. Members watch every show free.

“Nothing here is recorded. Ask the sky anything.”

Dr Ines Okafor, head of the dome

Every show is steered by hand by one of our six astronomers, who reads the room, slows down when the Moon gets a gasp and takes questions in the dark at the end.

At the console this month: Ines Okafor, Tomás Reyes, Hana Mori, Callum Reid, Priya Nair and Sofia Lindqvist. Each of them has a favourite stop, and you will hear which.

When it’s clear, the roof opens

On clear Friday and Saturday nights the roof of the east tower slides back and a 40-centimetre telescope points wherever the astronomer on duty decides.

School trips to the edge

Weekday mornings belong to schools. Every visit is matched to the age in the room, and teachers come free.

  1. Ages 5 to 7

    Small Sky, then an hour with torches and balls working out why the Moon changes shape.

    90 minutes · £6 a pupil

  2. Ages 8 to 11

    The planets at true scale, ending with the class steering the dome to a world of its choosing.

    2 hours · £7 a pupil

  3. Ages 12 to 16

    How we measure what we cannot reach: parallax, spectra and the rooftop telescope when the sky allows.

    Half a day · £9 a pupil

After dark

Once a week the dome stays open late for something that is not a show at all.

  1. A group of people sitting out under the Milky Way

    Orionids from the roof

    Meteor watching on the observatory deck, with the warm dome to come back to.

    Wednesday · 22:30 to 02:00 · £12

  2. Four cellists playing on a dark stage

    Four cellos, one sky

    A cello quartet plays under a sky that turns at the speed of the music.

    Saturday · 21:30 · £22

  3. An audience sitting in the dark facing a beam of light

    Sleep under the dome

    Bring a sleeping bag. The sky runs all night in real time, and breakfast is at sunrise.

    Saturday · 20:00 to 08:00 · £45

  4. Silhouettes of a crowd under blue stage lights

    Deep listening

    An ambient set for lying flat, with the whole room in near darkness.

    Friday · 22:00 · £16

Before you lie back

Is it suitable for young children?

Small Sky is made for ages three to six and keeps the lights a little up. Every other show suits seven and over; babies in arms are welcome at Small Sky only.

What if I get motion sick?

Our flights are slow, but rows A to C at the back feel the least movement. Ask at the door for an aisle seat there, and look at the horizon line if you need a rest.

Can I come in after the start?

The doors close when the lights go down. If you are late, we move your ticket to the next show at no cost.

Is the dome accessible?

Step-free from the street to the seats, six wheelchair spaces, a hearing loop and a relaxed show with the lights half up on the first Sunday of every month.

What happens if the roof is clouded out?

The telescope evening moves indoors to a live tour of the same sky under the dome, and your roof pass stays valid for the next clear night.
