They say it has water, and it does not rotate, its revolution period is 13 days and its 1.3 times denser than earth however it is livable... Oh yes its in the Libra galaxy

First.. Libra is not a galaxy.. but a constellation..!!
Secondly.. the scientists are still trying to find out if it rotates or not.. if it does, then maybe life is possible.. but if it doesn't.. then..??
Thirdly.. as its revolution period is equivalent to only 13 Earth days.. I feel it's too fast.. our Earth takes nearly 365 days to revolve around the Sun.. and we do not feel the movement.. but going around the same path in 13 days..!! we'd be literally swept off our feet..!!
And finally.. as somebody else said.. the planet(?) is almost 20 lightyears away.. so what the scientists have seen is - what the planet was - 20 years ago.. how do we know where it is now..??

Libra GALAXY??? Ok, I'm gonna start by assuming you mean the Libra CONSTELLATION.
How can it not rotate? Or, do you mean that its rotation is equal to its orbit around its star? If so, then colonization would be a problem, since one side is permanently in darkness while the other permanently in the light.
Of course, the very idea of colonizing another planet, especially one so far away, is one for our great-great grandkids, but it's still cool to think about it.

Well, it is the FIRST to be found where the temperature range is similar to that of earth. However, they have absolutely no idea whether there is water. The planet Gliese 581 c is 5 times the size of earth. The estimated temperature is between 0 °C and 40 °C.

Gliese 581 c has free flowing liquid but they aren't sure that it's water.
But at the temperatures on the planet, it's a good guess.
Water means life. I for one would not be surprised if there was some kind of life there. But I'll be long dead when someone finds out.

sounds awsome. except they are not positive there is water and the gravity is 2x as much as our so it would be very uncomfortable except for like reallly skinny people. and the atmospere might be too thick to actually sustain life it might just crush it intirely, and smother out what little sun it has. but if it is like earth that would so rock but the probablilty is like scully said.
" I think the only thing more fortuitous than the emergence of life on this planet is that, through purely random laws of biological evolution, an intelligence as complex as ours ever emanated from it. Uh, the, the very idea of intelligent alien life is not only astronomically improbable but at it's most basic level, downright anti-Darwinian." but we can always keep looking:)

Ok it is there or is it just where u saw it. That light has traveled many years to get here and a good comparison is the shooting of flying birds ,u shoot where the bird is going to be or u will miss it. With everything moving the way we are it would take a lot of GOOD calculations to come closet and closet doesn't Winn a cigar.

And it takes 20 years to get there on a light-speed aircraft. So, colonization is out of question.
