Gliese 581- is a red dwarf star, which means it is smaller than our own. It was given a huge attention by the astronomers to seek for the "first other habitable planet". The star system was first given attention , in April 2007 when they had found "planet c" (one of it's planet) as morelikely be habitable.
But after having further studies, they found out that "C" is having a greenhouse effect and too hot to be habitable (analougous to Venus)
Another planet has been found in subsequently, named "D". But it is beyond the boundaries of habitable zone (analougous to Mars)
In April 2009, exitement come upon, when they discover the Planet "G". It is just between "C" and "D". More likely to being found to have similar conditions suitable for liquid water on it's surface.
-Well, on my own part, this discoveries is break-through human knowledge. Yet, others maybe thinking it's againts some of our own beliefs, and others may think this is SO cool. But facing facts, for me, there's nothing, or anything wrong about knowing or having knowledge. It's just that, maybe, we should know first if we'll make it posible, or just leave it as a memory.
