NASA Kepler Discovers Earth-size Planet in Habitable Zone

NASA's Kepler Space Telescope Discovers

Earth-size Planet in Habitable Zone

NASA announced today that its Kepler Space Telescope has discovered an Earth-size planet in a habitable zone around a distant star.  The newly discovered planet, Kepler-186f is about 500 light-years from Earth in the constellation Cygnus. From a habitable sense, the planet is right in the sweet spot for life as we understand it.  The orbit of Kepler-186f is about 130 days compared to our 365, but its star is a red dwarf and about half the size and mass of our sun.  In the habitable zone, there is a strong potential to find water in a liquid form and not ice or evaporating is gas once its expelled from under ground.

Now, the size of Kepler-186f is also very important.  This planet is approximately 10% bigger than the Earth.  That means two things.  First, a mild difference in gravity for humans (if we ever reach it) and second, there's a better chance of this planet being a rock like planet and not a gaseous one.

We are still a long way away from observing this planet better. even with our newly planned space telescopes, but finding a planet that meets these two important criteria is something to celebrate!  We could be looking at our first real opportunity to encounter life on a distant world and not just microbes.  Scientists and science fiction fans are already excited and like me, cannot wait to see what we're going to uncover next.
