New planet discovered: Could humans live there?

Scientists have discovered an earth-like planet found in a region where temperatures could sustain life. If confirmed, the exoplanet, named Gliese 581g, would be the first Earth-like world residing in a star's habitable zone. Found in the “Goldilocks zone”—not too hot, not too cold to sustain life—researchers said it is highly probable that life exists on the planet. “My own personal feeling is that the chances of life on this planet are 100 percent," said Steven Vogt, a professor of astronomy and astrophysics at the University of California, Santa Cruz. "I have almost no doubt about it." Reaching the planet, however, would be no easy task. Gliese 581g is 20 light-years from Earth—that’s about 120 trillion miles away!
