Moons have long been considered mere supporting cast members within the solar system. But a spectacular yet accessible new show screening in the Sir Thomas Brisbane Planetarium's Cosmic Skydome has finally rocketed these bit players of the universe onto centre stage.
Narrated by Ed Helms, Moons: Worlds of Mystery explores the diversity of lunar landscapes, incorporating everything from volcanoes and geysers to ice-covered oceans and methane rain. This is no Earth-centric production either: attention turns to several of the more than one hundred known moons throughout the solar system, orbiting five of the other planets.
For example, Titan, which orbits Saturn, is the second largest moon in the solar system - larger even than the planet Mercury. It has a thick atmosphere and lakes and rivers of liquid methane and ethane which undergo something similar to the water cycle on Earth.
