A "Second Earth" has been found 20 light years away. Do you think there is life over there?

Scientists have discovered a warm and rocky "second Earth" circling a star, a find they believe dramatically boosts the prospects that we are not alone.

The planet is the most Earth-like ever spotted and is thought to have perfect conditions for water, an essential ingredient for life. Researchers detected the planet orbiting one of Earth's nearest stars, a cool red dwarf called Gliese 581, 20 light years away in the constellation of Libra.

Measurements of the planet's celestial path suggest it is 1½ times the size of our home planet, and orbits close to its sun, with a year of just 13 days. The planet's orbit brings it 14 times closer to its star than Earth is to the sun. But Gliese 581 burns at only 3,000C, half the temperature of our own sun, making conditions on the planet comfortable for life, with average ground temperatures estimated at 0 to 40C. Researchers claim the planet is likely to have an atmosphere. The discovery follows a three-year search for habitable planets by the European Southern Observatory at La Silla in Chile.

"We wouldn't be surprised if there is life on this planet," said Stephane Udry, an astronomer on the project at the Geneva Observatory in Switzerland.

Two years ago, the same team discovered a giant Neptune-sized planet orbiting Gliese 581. A closer look revealed the latest planetary discovery, along with a third, larger planet that orbits the star every 84 days. The planets have been named after their star, with the most earthlike called Gliese 581c. The team spotted the planet by searching the "habitable zone".

    Would be fascinated to know if there was indeed life there, whether or not they had surpassed us on technology.

    Its a possibility the earth explodes and we are pushed into space to survive our bodies evolve to be small and fragile no longer needing muscles in space and our heads become abnormally large considering our brains are the only things keeping us alive, our pupils evolve to become large and take up the whole eye (eyes we evolved) considering the lack of light in our new space environment -we are the greys- we just survived like humans do bum bum buuuum (just another what if)

    We are not alone in the universe. There is some type but a living being like us it could look like us it may not but all the stuff earth found how could there be nothing with us.

    Life created by accident? They make it sound so simple. Just find a so called "habitable" planet and the next thing you know, you have life. Give me a break.

    Honestly, this is quite entertaining. Has everyone forgotten about TIME?? It is in perfect conditions as we see it now, but in reality we're seeing what it WAS, 20 light years (1892105680000000000 regular years) ago. lol

    You are mistaken. A light year is a measure of distance, not time. It is the distance that light travels in a vacuum in one year, about 5.88 trillion miles. It has taken the light from the star around which this planet orbits 20 years to reach the earth, not the very large number you write.

    Well, there is bound to be life on many planets, ass life probably originated in the deep hot earth, below the surface. the most primitive life on the planet lives deep in rocks on our planet, but it seems unlikely that complex life is common. It took huge fortune to get to complex life on our planet, and inteligent life too, and life created the atmospher on our planet, with oxygen and Carbon. it is a given that all life is based on carbon, as there is nothing else that can form as many bonds as easily and is so versitile, with the exception of sillicon (which forms most of the rocks on the planet.

    and nothing is going to use helium as something to live off, as it is unreactive and therefore not much use

    Sometimes I get really troubled when I read that our scientists think that in order for a planet to have life it must sustain an atmosphere like ours. Remember that we evolved to accomodate our atmosphere and not the other way around. "Life" then can evolve in any other atmosphere in response to the particulars of that environment and may be helium dependant for instance. Our search therefore for other life forms should be more open to include that which befuddles the imagination. However this does not mean that we should not be searching for planets with similar atmosphere as, should we need to, they can provide us with alternative living arrangements

    I don't think aliens have come here, but I think it is a mathematical impossibility that we are the only life in the universe. Whether it's on that specific planet or not, I have no clue.

    if there is life here, think of the trillions of other solar systems. life must exist over there too! and they may be asking the same exact questions...

    oh boy ! another planet we can eventually desecrate and destroy.it is a pretty elitest attitude to think we are the only form of life in the universe.i hope we are visited by an aliens in my life time,i want to see the whole world freak out when everything sheeple have been indoctrinated to believe is blown apart.it will probably would be the end but i would like to see it before we destroy ourselves.

    Sounds like a good place to escape to though when global warming has completely done its harm.
    Someone needs to invent a lightcar so we can get there while we're still alive.

    Not where I live.
    This Summer it began hot, as usual, now it's cold again and it feels just like Winter. I think Winter had more sunny days than this Summer so far.

    Actually, do you know that if the polar caps melt; the water level will be so high, that the sun will not be able to hit as much earth as it does now... So globally, all temperature would drop quite a few degrees.

    oh boy, well, again with ohio...i went to the circleville pumpkin show to march with the select band this year, and it was sooooooooooo hot, two girls threw up, we were all suffering from heat exhaustion and i swear that if it had been 1 degree hotter, some of us wouldve died or something. now the day before was 50 degrees, and the day after, when my sister marched with the high school, it was below 30 degrees. tell me how that is 'global warming.'
