"The Earth-like planet that could be covered in oceans and may support life is 20.5 light years away, and has the right temperature to allow liquid water on its surface."
Seriously cool stuff, I love to be living in the time when we're first finding these things. I remember being taught in jr. high science that our solar system was probably unique, or atleast extremely rare....then they figure out how to detect planets orbiting around stars and are like "Oh...it looks like most stars have planets. Then they were like, "Well all the planets we're seeing are giants and not hospitable for life...Then they get telescopes powerful enough to see smaller planets, and it seems one of the first places we look we find a world very similar to our own. Its never seemed more reasonable that there could be billions of planets supporting life out there. If even half a percent of the stars in our galaxy alone harbor earth- like worlds that's still a billion life supporting worlds. Something about that thought is enormously comforting.
