Science is awesome update 1
NASA have discovered an exoplanet they believe to be the 'most Earth-like' ever. It is 10% bigger than Earth, and lied in its suns habitable zone. This means that liquid water could survive on its surface. Kepler 186f is the furthest planet out in a system of five planets. However, any life that could exist on this planet has to deal with a large dose of radiation as the star, Kepler 186 is a very active M-dwarf star, 795 light years from Earth.
