Explore the surface of our Moon
Join our astronomers as we take a closer look at our nearest neighbour.
To celebrate the arrival of Mirror Moon, a 2-metre scale model of the Moon by artist Luke Jerram, our astronomers will be investigating the lunar surface, from mountains to maria. Learn why the Moon is far from the smooth ball it can appear to be and even get the chance to make your own crater!
And, of course, our astronomers will be on hand to answer all of your questions about space and astronomy.
