“The study of Gliese 581c by the von Bloh et al. team is quoted as concluding “The super-Earth Gl 581c is clearly outside the habitable zone, since it is too close to the star.”[4] The study by Selsis et al. states that “a planet in the habitable zone is not necessarily habitable” itself, and this planet “is outside what can be considered the conservative habitable zone” of the parent star, and further that if there was any water there then it was lost when the red dwarf was a strong X-ray and EUV emitter, it could have surface temperatures ranging from 700 to 1,000 K (427 to 727 °C), like Venus today.”
Our definition of “life” is very narrow. Let’s broaden it to the widest possible definition: A lifeform is any self-sustaining system that takes in energy against the entropic gradient to synthesize information storage/replication-systems for the ultimate purpose of creating a new generation of lifeforms. Once we broadened the definition, then we are no longer constrained by the Earth-centric conditions.

Oops. A message to nobody I guess. :(
