Life could exist on planet just 6 light-years away: Scientists
A super-Earth planet orbiting Barnard's Star six light-years away, the second closest star system, could support primitive life, two American scientists have claimed. The rocky planet is believed to have surface temperatures about -170Â°C. However, researchers said it could have a large, hot iron/nickel core and enhanced geothermal activity, which would allow life to flourish under its icy surface.
