Pack your suitcase? Super-Earth Gliese 581d is in the ‘Habitable Zone’

One of the important goals of exoplanet science is to discover habitable planets that have the necessary conditions for life to form and thrive. Such planets will exist within the ‘habitable zone’ of a star. In this paper, the authors present Global Circulation Models which suggest that Gliese 581d could be in the habitable zone if it has a thick carbon dioxide-rich atmosphere.
