Located next to Madame Tussaud's, the planetarium explores the mysteries of the stars and the night sky. The most recent show starts with a spaceship of travelers forced to leave their planet when a neighboring star explodes. Accompanying them on their journey, the audience travels through the solar system, visiting its major landmarks and witnessing spectacular cosmic activity. There are also several hands-on exhibits that relate to planets and space. For example, you can see what shape or weight you'd be on other planets, and you can hear a recorded Stephen Hawking talk about mysterious black holes.
