So what can half-term visitors to the Treasure Planetarium expect? It all starts with a voyage on board the Legacy (as seen in the movie), taking passengers through the solar system, looking at each planet in turn. The destination is Treasure Planet (of course), but along the way you will witness supernova explosions, get sucked into a black hole, and end up back at base via a wormhole. As Grafton observes, 'there's an awful lot squeezed into one voyage'.
