A team of astrophysicists from the University of Bordeaux and Observatoire Astronomique de l'Université de Genève is suggesting that some exoplanets may not have been too hot during their formative years to harbor life today. In their paper published in the journal Nature, the group suggests that due to factors not considered in the past, some exoplanets may not have grown so hot that they lost the water in their atmospheres to evaporation into space.
