Hundreds of Exoplanets have been discovered in the last twenty years orbiting stars outside of our Solar System. Many of these worlds have been described as ‘Hot Jupiters’; planets which have a similar mass to the largest of our planets, Jupiter. Most of these types of exoplanets orbit very close to their parent stars making them much too hot for life to exist taking only a matter of days to complete an orbit. While the search for liveable planets is thought to be most likely in the habitable region, in ...
