It worries me that the Kepler spacecraft has found practically no planet candidates (OK, 4) with an orbit further from the star than Earth is. This means that of those 2321 planet candidates the only ones that are in the so-called habitable zone are those around red dwarfs, and that's not a great prospect. Where are the planets further out? Kepler ought to be able to find very many of them - a dip in the light curve of a star from a planet a long way out is just as strong as a dip from a planet closer in.
