In September 2010, a team called Lick-Carnegie Exoplanet Survey, led by principal investigator Steven Vogt, found what seems to be an another Earth-Like planet, called Gliese 581g, they said this is a planet where humans can move to, it has all the needs we want, the normal temperature(the global surface of the planet is -31 to -12 degree celsius), it has Oxygen, Water, and Food, i am not very sure if theres any animal in there, but i can say, it will be. It has the same face of earth. But unfortunately, it's 20 Lightyears away from here, i don't know if we can make our way to there :l who knows.
