Earth Like Planet

European astronomers have found a new planet, revolving a star about 20.5 light years from the Sun and Earth, that is the most similar to Earth yet found. It has about five times the mass of Earth, so it would be difficult for us Earthlings to live there, but its orbit is on such a distance from its star that it can hold liquid water. As far as we know, liquid water is a necessary ingredient for Earth like life. I wonder if there is intelligent life on that planet, life similar in intelligence to dogs and humans. Maybe my great great great great grandpuppies will know.
