I hesitated to blog this one for a while because the news seemed to be kind of a mess. News reports and at least one associated scientist said NASA's Kepler orbiting observatory had found hundreds of "Earth-like" planets. That didn't really make sense. Kepler can determine size and orbit, but that's a long way from declaring it Earth-like Out of the muddle comes the correction that "Earth-sized" (less than 3x the diameter of the Earth) was meant. So it's still big news, just not AS big as it seemed.
