An international collaboration including scientists from NAI’s International Partner, Groupement de Recherche en Exobiologie (GDR Exobio), published recently in Astrophysics their new ideas about the temporal evolution of the circumstellar habitable zone. They describe the possibility of an icy planet in orbit around a star becoming “revived,” and potentially habitable as the star leaves its main sequence. GDR Exobio collaborator Bruno Lopez of the Observatoire de la Cote d’Azur told NASA, “Our result indicates that searches for life-giving worlds outside our Solar System should include planets around old stars.”
