How different would life be elsewhere?

  • Julian Chela-Flores
Part of the Cellular Origin, Life in Extreme Habitats and Astrobiology book series (COLE, volume 20)


Prior to discussing the possible environments for life and intelligent life in the universe, (a topic addressed in the next two chapters), it is appropriate to discuss the following question: How can we test both the habitability of planets around other stars whether life may have evolved on a habitable Earth-like planet outside our Solar System.
