Apparently, astronomers in California have found what they believe could be a habitable plant orbiting the star Gliese 581 (http://en.wikipedia.org...), which is about 20 light-years away from Earth. The planet, called "planet g," is between 1.2 to 1.4 times Earth mass, and is "tidally locked" with Gliese 581, meaning that one side is always facing the Sun, and one side always dark, so one side always hot, the other side perpetually cold. Scientists suspect that, regard, water could still work on the planet, and that a human-habitable zone straddling the light and dark sides could exist.

Another funny thing is that a radio message from Earth is due to arrive there in 2029, so if there is life, we don't have to wait too long for a response. Not even a lifetime, actually.

So, what does everyone think?

maybe we already have. or the Vatican anyway. I saw this History channel show on the history of aliens and UFO stuff and insinuated that the pope must know something we don't to all of a sudden say You could believe in aliens and God and it not be contradictory or anything. so maybe they sent out a radio signal earlier than the known radio signal. and got word back from that planet.

granted that is just a unprovable conspiracy theory but it would be interesting if that were true.

Unfortunately, even if there is life on the planet and they respond we won't receive the reply until 2049...

Say we did get a signal from the planet though - I wonder how the Bible-bashers would explain that one away?

I read about this today.

It is very fascinating and I certainly hope that we find more about it. It would be interesting to see if there is any form of life out there - and I am sure that it is different in many ways to anything that we know of.

First that is a statement not a question. Second I would assume something like "what is the probability that we are the only intelligent life?" Plus a whole bunch of science and math and sh*t I couldn't care less about. All I know is I never believed earth to be the only inhabited planet.

Habitable for us, just means that there is presence of liquid water.

There are still many hurdles to pass for us to find life on other planets. But i suppose its worth a shot.

Probably much like anything else. Some (likely very few at first) would accept it and rationalize it by changing their beliefs slightly so that it fits in. Probably most would question its authenticity by saying it wasn't sent by aliens.

Eventually, there would be a group that would categorize it with dinosaur bones and say that the signal was sent from god to question our faith.

If it's 20 light years away they may been listening to our signals for years.
I am voting for Innomen because of his intelligence, common sense, humility and the fact that Juggle appears to listen to him. Any other Presidential style would have a large sub-section of the site up in arms. If I was President I would destroy the site though elitism, others would let it run riot. Innomen represents a middle way that works, neither draconian nor anarchic and that is the only way things can work. Plus he does it all without ego trips.

So it's stationary? And you refer to "the sun"; I would hope our galaxy isn't that extensive and that it has a different sun :P. And given that it has its own solar system, I would assume it isn't stationary and that it orbits. Therefore it would have 4 seasons in which the areas rotate. You have vertical quadrants 1 - 4 and seasons a - d; in season a you have all sun, season b you straddle light and dark, c is all dark and d is straddling it. Every time period defined by one of the seasons will mean that 1 - 4, as they originally correspond to a - d, will then become

1 2 3 4
b c d a

then

1 2 3 4
c d a b

etc.

I find problems with the possibility provided, but nonetheless it is very interesting. Oh, and you said the radio message would arrive by 2029 to there. What if

1) They don't have the tech to receive it?
2) They don't have the tech to send messages that far, or locate where they came from?
3) We miss? :P
4) Even if it does arrive and they send one back, it would take twice the time you propose for us to find out because 19 years is one way; we need the round trip.

It does not rotate on an axis - it orbits, however. Like the Moon is with Earth, the planet is tidally locked with Gliese 581 - one side will always face Gliese 581, while the other will not.

; And you refer to "the sun"; I would hope our galaxy isn't that extensive and that it has a different sun :P.

Simple mistake on my part.

1) They don't have the tech to receive it?
2) They don't have the tech to send messages that far, or locate where they came from?
3) We miss? :P
4) Even if it does arrive and they send one back, it would take twice the time you propose for us to find out because 19 years is one way; we need the round trip.

This goes for Cody as well - it's just a funny tidbit to add on to the entire subject. Please do not take everything so seriously.

it does rotate. if it didn't the same face wouldn't always be to the center, it would always be facing some fixed point in space. when astronomers say an orbit is tidally locked, they just mean that the rotation and orbit have settled to the same rate.

see!

They do, but since the conditions that brought about life on this planet are the only conditions that we know can do so, that is what they look for.

they've considered other substances, such as ethanol, to be the basis for life as well, but water is just so perfect for the job it seems more likely. also it makes sense to look for lifeforms at least somewhat similar to us because otherwise we'd have no f*cking clue what we were looking for and no way to know when we've found it.
