New observations reveal how pristine, primordial dust aggregates to form rocky planets around other stars. One question astronomers would like to answer is how common such Earth-like planets are and whether solar system formation proceeds routinely around other stars.

IMHO. Given the prolific success of Geoff Marcy, et. al. I'd think this is a pretty silly question. AND...just because we cannot yet detect Earth size/mass plantes, does not mean they are not there. :roll:

Of course, but we do not know how common terrestrial planets really are. It is possible that gas giants are much more common.

BTW, I posted a message (http://www.badastronomy.com/phpBB/viewtopic.php?p=370644#370644) on this same subject earlier.
