There's been considerable debate over the existence of Gliese 581g ever since the discovery of the "Goldilocks" planet was first reported nearly two years ago, but new research claims to provide additional evidence that the potentially habitable "super-Earth" really is out there. The prospect of the extrasolar planet, which is said to orbit the red dwarf star Gliese 581, 22 light-years from Earth, is an exciting one. It's thought to lie in the star's "habitable zone," where liquid water could exist on the planet's surface.
