JWST is the pinnacle of our astronomical aspirations, the most sensitive telescope ever built by human hands. But can this feat of engineering resolve a question which has haunted us since the dawn of civilization - are we alone? So let's explore whether JWST could detect signatures of biology on another world, and if so under what conditions?
