Have you heard of the new planet Gliese 581 C, which has almost same climate as earth, and it has liquid water on it?

Yes, I have and also know that it would take aproximately 21 years to travel there if travelling the speed of light (if I'm not mistaken)

Yes I have heard of it. Apparently the fastest space craft we have at the moment would take 5 billion years to get there, by which time the human race probably won't exist anymore anyway. It's quite interesting to speculate on whether life does inhabit this planet but I feel it is ultimately pointless. Certainly I don't think we'll know much more about it in my lifetime and I really doubt we'll ever go for sure. Would a mission to this planet (if possible in the future) even be worth funding when we have so many things here on Earth that need concentrating on?

Don't get too excited - we don't *know* it has liquid water, it is only *possible* that it *could have* liquid water. Its size and orbit are such that water might exist. On the other hand, if we can find such an earthlike planet (even if it isn't truly earth like) with a distance which, in cosmic terms, is very close indeed, it makes it very likely that there are literally millions of such planets in this galaxy alone, let alone the rest of the universe. The odds on some for of life being out there somewhere went up, in my opinion.
