"NASA’s Kepler Space Telescope recently discovered an Earth-like planet orbiting a nearby star within the habitable zone of our galaxy. Kepler-186f is approximately 500 light-years from Earth in the Cygnus constellation. The habitable zone, also known as the Goldilocks zone, is the region around a star within which planetary-mass objects with sufficient atmospheric pressure can support liquid water at their surfaces. While it has been estimated that there are at least 40 billion Earth-sized planets orbiting in our Milky Way Galaxy, this particular discovery is labeled the first Earth-sized planet to be found in the habitable zone of another star. What this means is that if the nearby star to this planet is similar to our Sun, then the probability of life on this planet exponentially rises." I mean we can't see it up close, so who knows, but its in the right zone as we are. NASA simulated comparison of a sunset on Kepler-186f and Earth. On Kepler-186f the star looks dimmer but slightly larger.
