'Goldilocks' Planet's Temperature Just Right For Life

Astronomers have, for the first time, spotted a planet that is considered to be in the "Goldilocks zone," meaning that its environment is just right to sustain life: not too hot, not too cold. Scientists approximate that it is about three times the size of earth, and orbits its version of the sun every 37 days.
