Life beyond in the stars?

The recent pronuncement that Gliese 581g, a planet orbiting the red dwarf star Gliese 581 may be suitable for life should not come as any surprise. Located approximately 20.5 light years away from Earth in the constellation of Libra, the planet is located in the middle of the "Goldilocks" zone, or what is defined as a habitable part of space near its parent star. The existence of liquid water is considered a strong possibility and this condition is generally considered a precursor for life. The planet was discovered by the Lick-Carnegie Exoplanet Survey following a period of over ten years of observations. Gliese 581g is believed to be the first Goldilocks planet ever found being the most earth-like planet with the potential for harboring life. The search for life in the universe continues both through optical astronomy and radio astronomy (the SETI program). The question remains, if life is found, what would the human race do?
