Newly discovered planet 'habitable'

Astronomers have discovered the first planet outside the solar system with the potential to support life.
The planet orbits a red dwarf star called Gliese 581, 20 light years from Earth, in the middle of the star's habitable zone, meaning that temperatures on its surface are just right for life to develop.
US-based scientists found the planet using precise measurements from the Keck telescope in Hawaii, which has been scrutinising Gliese 581 for more than a decade.
The new planet, called Gliese 581g, is one of several known to be orbiting the star, but is the first to be discovered in the so-called Goldilocks Zone, where the distance from the star means that temperatures are neither too hot or too cold for life to exist.
