Museums at Night: Explore Your Universe

As part of the hugely popular annual Museums at Night event, the observatory offers a wide range of events suitable for an equally wide range of ages: in 'We Are Aliens' Rupert Grint of Harry Potter fame introduces a planetarium show that tries to answer the ultimate questions about the universe; a special Ask the Expert session looks at cutting-edge projects in astronomy and space exploration, and there's the chance to make a planet finder. Some events are free; see the website for details.
