The mysteries of the universe became a little clearer as experts shed light on galactic goings-on as part of the Norfolk and Norwich Festival.
A huge, inflatable moon, is at The Forum as part of Bristol-based artist Luke Jerram's Museum of the Moon installation.
On Saturday, as visitors to The Forum moonbathed on deckchairs beneath the lunar installation, people discovered more about the solar system and beyond.
Youngsters looked at models to find out how many moons the planets in the solar system have, courtesy of the British Science Association.
And Gerry Blake, from the Kinetic Science Foundation, explained all about exoplanets - planets which orbit stars outside our solar system.
There was also singing, storytelling and performances about the moon.
The Moon installation will be at The forum until Sunday, May 21.
