The article did say however that it could be something like neptune say,which has a lot of gas which is many times bigger than earth but its mass would be nearer,but it is in the right position,you never know there could be moons around it which could be good spots too.

As for physics at the moment it seems like supersymmetry will end up throwing up new physics first i think as increasing number of experiments prove that the standard model is wrong which is helping to answer the old question of why everything we can see is only something like 6% of the stuff thats in the universe. Exciting Stuff!
