Probing Distant Atmospheres for Life
Inevitably, the hunt for extraterrestrial life looks first for the kind of life we find on Earth. But we may have to widen that view, and the key is to make as few assumptions as possible. For if we've learned one thing from the 200+ extrasolar planets found thus far, it's that solar systems around other stars can be utterly different from anything we had imagined.
Even if humanity ultimately takes the dirtnap, the discovery of a living extrasolar planet seems almost inevitable. I wonder what our response will be, gazing at some tantalizing and alien world orbiting another star. What will we have done to ourselves -- and how might our collective predicament color our reception of a confirmed extraterrestrial biosphere?
Although real enough, the new Earth will also play a formative role in our imaginations; it promises to be a liminal frontier as well as an astrobiological focal point -- the locus of new myths, an imaginal haven forged of memes old and new, a distant and beckoning mirror.

Our society cringes at the idea of the liminal; we want yes or no, black or white. We want to be reassured, and if there's one thing the liminal is not, it's reassuring.
