the news of the discovery of a "Super-Earth" in a star system some 600 light years away from our solar system. Given the rather uninspiring name of Kepler 22b, the planet is twice the size of Earth and possesses a surface temperature estimated to be approximately 22° Celsius. It orbits a star very similar to our Sun at a distance that makes it plausible candidate for liquid water, as well as, possibly, life. Of course, there's no way to know for certain and there are still plenty of reasons why Kepler 22b may in fact be very different than our own homeworld. Still, it's very fascinating news if you're an astronomy buff or a fan of science fiction.
