NASA's Kepler Space Telescope has
found an Earth-sized planet within the habitable zone of the star it
orbits, the space agency announced Thursday. The planet, which NASA
calls Kepler-186f, is located in the constellation Cygnus, about 500
light-years from Earth. Orbiting the star Kepler-186 once every 130
days, it receives one-third of the energy from that star than Earth does
from the sun. Residing within its star's "habitable zone" is not a
guarantee that life is possible, but makes for a better chance that it
is. RT's Lindsay France has more on this interstellar discovery.
