The stunning discovery of seven Earth-like planets orbiting a small star in our galaxy opens up the most promising hunting ground to date for life beyond the Solar System, researchers said Wednesday. All seven are within 20 percent of the size and mass of our own planet and almost certainly rocky, and three are ideally situated to harbour life-nurturing oceans of water, they reported in the journal Nature.
