Ever since astronomers announced the discovery of an Earth-sized exoplanet less than five light years down the cosmic street, the question on every good space cadet's mind has been whether or not we can colonise it. We aren't going to know if Proxima b is habitable until we can point some very powerful telescopes at it, which won't happen until next year. But until then, scientists are playing around with models -- and one such modelling effort recently came to some promising conclusions.

Last week, astronomers announced that our nearest neighbouring star hosts an Earth-sized planet in the habitable zone -- an exciting prospect for alien life, and a possible second home for humanity. But before we assemble the interstellar welcoming party to greet our cosmic neighbours, we need to figure out whether Proxima b is capable of supporting life at all. Thanks to the James Webb Space Telescope, that question could be answered in less than three years.
