O'Malley-James, Carl Sagan Institute, Cornell University.Alien life could be evolving right now on some of the nearest exoplanets to our solar system, claim scientists at Cornell University in Ithaca, New York.
However, they also found that even for planet models with thin, unprotective atmospheres and those with ozone-poor atmospheres, surface UV radiation remains below early Earth levels, even during flares for the red dwarf stars they orbit. So any, or all, of them could support life, especially if it had protective features such as pigments or biofluorescence , or if it lived under soil, water or rock.
