Kepler is a space telescope designed to look for planets around other stars. Most of the exoplanet reports from the last couple of years come from Kepler. It's still going strong and Phil Plait wrote a very good article on the most recent discovery, Earth-sized planets: Two super-Earths found orbiting the same star.
"The two planets, called Kepler-62e and Kepler-62f, are both bigger than Earth, but not by much; they are 1.6 and 1.4 times the Earth’s diameter, respectively. Kepler-62e orbits the star every 122 days, while Kepler-62f, farther out, takes about 267 days. Given the temperature and size of the parent star, this means that both planets are inside the zone around the star where water on the surface could be a liquid. Now, to be clear, this depends on a lot of factors we don’t know yet: the masses of the planets, their compositions, whether they have atmospheres or not, and what those putative atmospheres are made of. For example, Kepler-62e could have a thick CO2-laden blanket of air, making its surface temperature completely uninhabitable, like Venus."
So there isn't a lot of news but this is pretty fun. Kepler will keep looking for planets and by the nature of the process, it takes longer to find smaller planets with larger orbits.
"For a planet to be in the star’s habitable zone, it may take months or even years for it to pass in front of the star several times (multiple transits are needed to make sure we’re not seeing some other event, like a starspot). That takes time, but Kepler has been observing these stars for years now, which is why we’re seeing more and more smaller planets now."
But yeah, it's fun to speculate...
"What an amazing thing that would be: two inhabitable worlds around one star (as opposed to all the Tatooines we’ve been finding)! It’s fun to imagine it being like a Victorian science fiction novel, spurring interplanetary travel and trade between alien races… or war. I guess that depends on which writer you read."
