Martin Posted October 16, 2007 Share Posted October 16, 2007 the exoplanet search is finding planets at a great rate and I expect that it WILL come up with some habitable ones not too far away----so that they can be studied with improved instruments. But I'm personally doubtful that Gliese 581 C is a good place for life. I think another planet at the same star might be a better prospect, namely Gliese 581 D. that is what these people say: http://arxiv.org/abs/0705.3758 and it makes a lot of sense. Planet C is pretty close in and could have been ruined by a runaway greenhouse, like our planet Venus. Planet D is further out and would be too cold EXCEPT for its presumed greenhouse blanket. There's some WikiP about these planets. http://en.wikipedia.org/wiki/Gliese_581_c http://en.wikipedia.org/wiki/Gliese_581_d The whole Gliese 581 system is interesting (tho can't be certain that it's actually habitable).
