Brian Cox and Robin Ince referee as Saturn and Jupiter square up to each other in a planetary face-off. Representing Team Saturn is space physicist Professor Michele Dougherty, and in the opposite corner is Dr Paul Abel on Team Jupiter. Katherine Parkinson judges this cosmic contest, casting the final vote to decide who will be awarded the coveted Kuiper Belt.

It is not all about looks of course, but it is a significant factor in a first impression. Both Saturn and Jupiter score highly in this department, boasting magnificent icy rings and colourful stripes respectively. But what lies beneath their aesthetically pleasing exteriors? How do the planets compare on the inside?

The gas giants have been subjects of investigation for many years, with historic missions like Galileo and Cassini uncovering their secrets. But they aren’t alone, each planet is surrounded by its own mini solar system of moons, which get space scientists just as excited as their parent planets do. Both Jupiter and Saturn have moons which are hot contenders in the search for extraterrestrial life and our panel discuss the future plans to explore them.
