[ExI] Newly discovered planet may be first truly habitable exoplanet!

[John Grigg]

"A team of planet hunters led by astronomers at the University of
California, Santa Cruz, and the Carnegie Institution of Washington has
announced the discovery of an Earth-sized planet (three times the mass
of Earth) orbiting a nearby star at a distance that places it squarely
in the middle of the star's "habitable zone," where liquid water could
exist on the planet's surface. If confirmed, this would be the most
Earth-like exoplanet yet discovered and the first strong case for a
potentially habitable one."
