For the first time, astronomers have discovered a planet far, far away that might be similar to Earth. This distant world, which pirouettes around a dim bulb of a star with the unglamorous name Gliese 581, may possibly sport a landscape that would be vaguely familiar to us - a panorama of liquid oceans and drifting continents. If so, there's the chance that it's a home to life - perhaps even advanced life.If there isn't life on this planet now, there will be in a billion years. A few billion more and we'll be able to talk to them. I hope I'm still around.
