If you think the Peter Harrison Planetarium looks good from the outside, imagine the wonders of the universe you can see inside!

London’s only planetarium can be found on top of the hill next to the Royal Observatory in Greenwich. Shows at the planetarium take real images taken from spacecraft and massive telescopes and allow you to explore the universe without leaving your seat.
