Astronomers have discovered a potentially habitable planet of similar size to Earth in orbit around a nearby star. A team of planet hunters spotted the alien world circling a red dwarf star called Gliese 581, 20 light years away. It is most likely to be similar to our Earth. Here the surface temperature is neither too cold nor too hot for the existence of life.
