There's currently no indication that the new planet discovered actually has life on it. If there is life, it could be as simple as microbes or it could be intelligent life not too much unlike our own. The premise of having parallel universes has long made us ponder the many possibilities of what lays out there in space.
Traveling to the new planet found is too difficult. No one would be able to reach it in their lifetime. However, scientists will study Gliese 581G for indications on the atmosphere, etc and find out more about it.
What do you think that the new planet discovered 2010 means?
