Another Earth?

A group of researchers from the Harvard-Smithsonian Center for Astrophysics have been researching the world beyond our solar system. The discovery of two new planets, about the size of Earth, has taken the news for a turn. The findings are a great jump for mankind, now knowing the ability to find more information about the outside world. The new planets, founded to be fairly unlivable, seem to be a great start for what is more to come. Could it be possible there is a planet outside our solar system that contains the living conditions similar to our own planet Earth?
