About This Show

The Moon is our nearest neighbour in space. Even with the naked eye, you can see bright regions and darker patches on the Moon. Use binoculars or a telescope and you will see a tremendous amount of detail. The large, dark plains are called 'seas', but there has never been any water in them.

Explore the Moon with us at the Planetarium - it's a rugged little world, with mountains, valleys, and a vast number of circular walled structures called craters. Learn about the phases of the Moon, how it raises the ocean tides, how it regulates Earth's climate, and how it is slowly making our day longer.

The Moon is also responsible for the phenomenon of eclipses. On Earth, an eclipse occurs when the Moon passes between the Sun and the Earth and the Moon’s shadow falls onto the Earth’s surface or when the Moon passes through the Earth’s shadow. So, there are two types of eclipses: eclipses of the Sun (solar eclipses) and eclipses of the Moon (lunar eclipses).

There are three main types of eclipse of the Sun – partial, annular and total. They can only happen at New Moon, but they do not happen every month because most months the Moon passes above or below the Sun in the sky at New Moon. You must always use proper safety equipment to view any type of solar eclipse. A partial solar eclipse occurs when the Sun, Moon and Earth are not exactly aligned and only part of the Sun’s brilliant disk is covered by the dark disk of the Moon. There was an eclipse like this, visible from Britain and Ireland earlier this month, on 12th August 2026.

An eclipse of the Moon can only happen at Full Moon when the Moon passes either partly or completely through the Earth’s shadow and the eclipsed portion of the Moon turns a beautiful brick-red, coppery-red or blood red colour. They can be stunning to watch. Unlike solar eclipses, watching a lunar eclipse requires no specialized filters or eye protection, making it completely safe to observe with the naked eye, a pair of binoculars or a telescope. Again, they don’t happen every month because most months the Moon passes above or below the Earth’s shadow in the sky at Full Moon.

There will be an eclipse like this, visible from Britain and Ireland, in the early morning hours of Friday, 28th August 2026.

Toilets

The Planetarium has two easy access, gender neutral toilets, one of which is slightly larger so as to accommodate carers if this is necessary.

Seating

The seats in the main auditorium are ex-aircraft seats. Those in the first two rows are set at a slightly reclined angle to provide the best possible view. They can, however, be tipped forwards to enable easier access to the rows behind when entering and leaving. The seats in the back row do not recline. They provide a wide view of the entire dome area, which some of our visitors prefer. The auditorium is fully accessible to wheelchairs.
