One of the several planets within the Gliese 581 star system, called Gliese 581 d, may be one of the most potentially habitable alien worlds known. It is about 8 times the mass of Earth, and located in an orbit just right for liquid water to exist on the surface. Water is a key ingredient for life as we know it. Gliese 581 is a red dwarf star 20.5 light-years from Earth An Earth-like planet spotted outside our solar system is the first found that could support liquid water and harbor life, scientists announced today. Liquid water is a key ingredient for life as we know it. The newfound planet is located at the Goldilocks distance-not too close and not too far from its star to keep water on its surface from freezing or vaporizing away. And while astronomers are not yet able to look for signs of biology on the planet, the discovery is a milestone in planet detection and the search for extraterrestrial life, one with the potential to profoundly change our outlook on the universe
