NASA announced Thursday the discovery of Kepler-452b, an exoplanet that’s a ‘close cousin’ to Earth.
If humankind ever is to escape this not-so-gently-used rock called Earth, we’ll have to find somewhere hospitable to stay.
That’s what makes NASA’s Thursday announcement of the discovery of a planet much like ours so, ahem, earth shattering. Kepler-452b is the first confirmation of a near-Earth-size planet that can sustain liquid water and orbits a star much like the Sun. It was found through data collected by the Kepler Space Telescope, launched into space more than six years ago.
