More than 6,000 exoplanets (planets orbiting other stars), one of the most rapidly expanding frontiers in science, have now been confirmed by astronomers. Their search of other worlds has been transformed within a span of thirty years, which started as a form of speculation, to accurate detection. However, in the midst of this wave of discoveries, scientists believe that the most exciting period is ahead. The following decade might not only change the exoplanet study to counting planets, but also analysing their atmospheres – and possibly even, their habitability.
