A planetarium visit without the coach trip
Sussex has a proud astronomy story: the Royal Greenwich Observatory moved to Herstmonceux Castle in the 1950s to escape London's light pollution, and its telescopes still welcome visitors. Our domes bring dark skies to schools and museums from Canterbury to Hastings, whatever the weather.
Every visit is live and presenter-led: pupils lie back under a full 360° sky, ask questions and see the night sky above Kent tonight. Shows link to the National Curriculum from EYFS to GCSE, and we can run back-to-back sessions so every class takes part on the same day.
