After years of research, an international team of scientists claim they have found a world beyond Earyh that might be able to support life. The planet, called Gliese 581g, is near the middle of the "habitable zone" of its parent star. That means it is just the right distance and temperature - not too hot, and not too cold - for liquid water to remain on its surface and where you have liquid water, you have the possibility of life.
