Exciting news: Scientists have discovered the most Earth-like planet yet circling a star 600 light years away. Kepler-22b, one of more than 500 planets found to orbit stars beyond our solar system, is the best positioned to have liquid water on its surface. Pretty much like our planet in all respects, although scientists are a bit uneasy at signs it has a much higher form of intelligent life. Yeah, that's right -- they've managed to come up with a college-football playoff system there. (Ba-da-bomp.)
