Our NASA's Spitzer Space Telescope has discovered the nearest rocky planet outside our solar system. Even though this exoplanet orbits too close to its star to sustain life, it could still be a gold mine of science data. That said, we won't be visiting it anytime soon because it's 21 light-years away! Learn more: http://go.nasa.gov/1KDfr7W ‪#‎NASABeyond‬
