Earth-sized planet discovered with 'mild' climate and peaceful parent star

A newly discovered planet orbiting a nearby star could be the closest world to Earth providing a comfortable home for life.
The Earth-sized planet, named Ross 128b, is just 11 light years away and thought to have a "mild" climate with temperatures ranging between an icy minus 60C and balmy 20C.
That could mean it has oceans and lakes in which life may have evolved.
