http://www.theguardian.com/science/2014/apr/17/planet-earth-like-discovered-kepler-186f'A newly discovered planet may be the most Earth-like yet found in another solar system, scientists believe.
Kepler-186f is almost the same size as the Earth and occupies its star's "habitable zone" where temperatures are mild enough to allow liquid surface water.
If the planet has lakes or oceans, it would increase the chances of life evolving there.
But anything living on the world may have to withstand extra large doses of radiation from its active sun, Kepler-186.'
