Royal Observatory Greenwich
London's only planetariumHome of Greenwich Mean Time and the Prime Meridian of the World. We’re also home to London’s only planetarium, the Harrison timekeepers, and the UK’s largest refracting telescope.
Think of a planetarium as a tour bus of the Universe taking you on amazing journeys to explore and experience the wonders of the night sky with expert commentary from real astronomers. A visit to the Peter Harrison Planetarium can fly you into the heart of the Sun, transport you to distant galaxies, show you the birth of a star or land you on Mars.
