Re: 'Rare Earths' meets high metallicity in SciAm
Interesting stuff. We've learned much lately and gained a changed perspective on the other Earths question. I'm sure we all agree that there is much more to learn. That's why I always prattle on about funding proposed missions to detect EARTHLIKE planets like the Kepler mission. Much less bucks than TPF and much sooner. We would then know, if there are ANY Earthsized bodies in water zone orbits around other stars. And how common/uncommon they were statistically. A major step.
