NASA’s planet-hunting Kepler Telescope has spotted the first roughly Earth-sized world orbiting in the “Goldilocks zone” of another star – offering perhaps the best bet so far for life elsewhere in the universe.
A year on Kepler-452b, which is about 1,400 light years from us in the constellation Cygnus, is 385 days, meaning its orbit is just a bit farther away from its star than the Earth is from the sun. That places it squarely within what planetary scientists call the habitable zone, or “Goldilocks” zone — not too cold and not too hot.
