An international team of astronomers including Carnegie's Paul Butler has found clear evidence of a planet orbiting Proxima Centauri,the closest star to our Solar System. The new world, designated Proxima b, orbits its frigid red parent star every 11 days and has a temperature suitable for liquid water to exist on its surface,if it were present. This rocky world is a diminutive more massive than the soil and is the closest exoplanet to us; it may even be the closest possible abode for life beyond our own Sun. A paper describing this milestone finding is published by Nature.
