Today marks a new record for exoplanet size, with the announcement of two further planets discovered by Kepler. These planets are the smallest discovered so far (well, except for the pulsar planets) with one even smaller than Venus. These two are far too close to their stars to be habitable however, so their discovery is only notable for their size/mass. And even if they were habitable they are too far (1,000 light years) to be reachable even by radio signals in the short term.
