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.

Combining real images from spacecraft and telescopes with advanced CGI, all projected onto a fully immersive dome, the 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.

The Peter Harrison Planetarium at the Royal Observatory, Greenwich is now London’s only planetarium, and features state-of-the-art HD projection technology, visualisations based on real scientific data and real astronomers.

New shows throughout the day – now better and brighter than ever. Experience a spectacular journey across the Universe at the Peter Harrison Planetarium.
