Come and experience the universe! Hands-on activities for all ages, multi-media presentations, poster exhibitions, artwork and installations, will showcase human understanding of the universe, in the western tradition, from the ancient world to the modern-day. From Babylonian Astronomy to  the medieval theories of sight, colour and astronomy; from Renaissance star-gazing to 18th century optical experiments, a blow-up planetarium, and a 3D fly-through modern galaxy-modelling in Occulus Rift technology. Engage with artistic collaboration with research into medieval and modern science: film, drawings, glasswork and projections and make your own astrolabe. Re-enactors will guide you to the past and through the event. Short talks on the hour will feature the exhibitors and the day finishes with a question and answer plenary with a modern scientist and a medieval historian.
