A Life of Gliese?
“Yesterday (Sept. 29), a team of researchers announced the discovery of Gliese 581g, a rocky, roughly Earth-size planet in its parent star’s so-called “habitable zone” — a just-right range that can allow liquid water to exist.
One of the planet’s discoverers said in a briefing yesterday that “the chances of life on this planet are 100 percent.” To determine if this is true, researchers will have to scrutinize Gliese 581g from afar, searching its atmosphere for certain telltale molecules.”

How unfortunate this planet has been discovered NOT to exist, sigh!
I shall unpack my bags and wait for another sighting, and possible home for humanity, because we do know our efforts on earth haven’t been all that nurturing for the long haul of mankind’s home base, sheesh!!!
