'100 percent' chance for life on newly found planet?

An artist rendering shows the four inner planets of the Gliese 581 system and their host star.

Gliese 581g may be the new Earth.

A team of astronomers from the University of California and the Carnegie Institute of Washington say they've found a planet like ours, 20 light years (120 trillion miles) from Earth, where the basic conditions for life are good.

"The chances for life on this planet are 100 percent," Steven Vogt, a UC professor of astronomy and astrophysics says. "I have almost no doubt about it."

The planet is three times the size of Earth, but the gravity is similar.

Dr. Elizabeth Cunningham, planetarium astronomer at the Royal Observatory in Greenwich, says the discovery is a huge deal.

"It could have liquid water on the surface," she said. "That's the first step to find life."

The Gliese 581 system's orbit compared to our own solar system. The planet labeled G is the one scientists believe could very likely support life.

There are hundreds of known extrasolar planets that have been discovered in the Milky Way, but this is the first that could support life.

Earthlings won't be traveling to Gliese 581g any time soon unfortunately. Scientists say a spaceship traveling close to the speed of light would take 20 years to make this journey.

But if we did - we'd find some other things familiar. The atmosphere and gravity are similar to Earth, and if you're from the polar regions, you'd definitely feel right at home. Scientists say the highest average temperature is about -12 degrees Celcius (10 Fahrenheit), but they point out that the planet doesn't have a night and day - one side continually faces the star and the other side faces the darkness of space. This means one side is blazing hot and the other freezing cold.

Gliese orbits a red dwarf star called Gliese 581. Cunningham says "it's a Goldilocks planet."

"It's not too hot, it's not too cold, it's just right" for water to form, Cunningham said.

The area is called the "Goldilocks zone."

Other planets near Gliese 581g have been discovered, but they are not habitable and are mainly comprised of gas. Gliese 581g, however, is a rocky planet.

It was discovered using the Keck telescope in Hawaii which has been observing the star Gliese 581 for 11 years.

"Keck's long-term observations of the wobble of nearby stars enabled the detection of this multi-planetary system," said Mario R. Perez, Keck program scientist at NASA headquarters in Washington.

Astronomers are excited this new planet was discovered so fast and relatively close by.

"I'm surprised we found one so fast," Cunningham said. "The implication is either we were very lucky or these planets could be relatively common."

Gliese 581g is in the constellation of Libra. While Earth takes 365 days to orbit our star, the sun, Gliese 581g orbits its star in 37 days.

      I am sure of life on other planets-no speculaltion there. I guess they can see it's not rotating ,so no day and night, but how can they tell its gravity is 3 times the Earth???? Where do they get that from??? How do you weight space bodies light years away???? Are they kidding us?

      Lance, we couldn't destroy this planet if we tried. We could at best make that paper thin layer that sits on its surface (aka, the biosphere) inhospitable to ourselves for a time. But natural phenomena could do it much better (and will, its unavoidable in the long run), with results lasting much longer.

      Besides, since we have not found any other intelligent life as of yet, that means for us Humanity is the MOST IMPORTANT THING IN THE UNIVERSE. I would wreck the fleeting surface conditions of a THOUSAND worlds in order to insure Humanity's survival.

      arthurr: a measure of a planet's mass (which, along with its radius, allows you to calculate the force of gravity on its surface) is fairly straightforward and involves looking at the orbit of the planet around its star, along with the orbits of any other planets in the system. If the planet has a moon, it's very easy to calculate its mass by looking at the orbit of the moon. Otherwise you need to use some more advanced methods and look at the effect that the planet's gravitational pull has on the orbits of the other nearby planets.

    • Greg

      uhhh they said right in the article how the mass was weighed... by observing the subtle wobble in the star. Every mass in the universe attracts other objects, so the planet is essentially pulling the star slightly toward itself as it circles. The only reason the star remains somewhat stationary is because it is bigger.

    • Steve

      Arthurr, you can calculate the mass of the planet if you know the distance from the star, the star's mass, and the planet's orbital velocity. It's not hard to get within 5% of a star's mass, and it's easy to solve from there. Any high-school physics student can do it.

      Authurr:

      I imagine they are calculating the weight by the amount of gravity it has. Gravity is proportional to the weight of anything. Believe it or not, even you have a very small amount of gravity.

      I can just see: 20 years in deep space on the USS MAYFLOWER and all of us are suffering from cabin fever. Finally, we land on the bad side of this planet and are greeted by naive iron age equivalent natives. They have no real weapons to defend themselves against our pulse microwave rifles or miniature nukes. They help us out that first year, whatever that is, by sheltering us and giving us the taste of real food for the first time since leaving earth. We are introduce to their culture and we learn, and learn, and learn until we pretty much have them figure out and their planet. Our scouts have long been around and about surveying all the wonders of their planet while the rest of us play the grateful visitor. Then suddenly there are more ships from earth and we overwhelm them. We suffocate them into our 24/7 news cycle culture and bad cable tv programming. The natives revolt. We now look at them as an inferior race not worthy of the land they stand on. We send them permanently to the dark or bright side of the planet and let them figure it out. Last but not least we declared MANIFEST DESTINY and that ALL SPECIES ARE CREATED EQUAL.

      "A chance of life" does not equal in any way "a chance of intelligent life."
      While intelligent life is very probable given the size of the universe, chances of its being on a planet only 20 light years from us is infinitesimally small.

      arrrthur: Gravity can be measured many ways including the pull it has on other objects orbits. I took Astronomy 101 which is all you need to understand that they are not kidding us. There are ways of detecting these things. For example, you can tell how big a planet is by measure how dim a star becomes at certain times. This dimming is the equivalent of an ant walking across a headlight. Not notable to the naked eye, but technology can see the difference. They are very serious.

      Since this planet isn't constantly revolving like our own, how does it maintain its atmosphere? I thought you had to have a rapid rate of rotation in order to have a magnetic field which protects the atmosphere from being broken down by solar energy. How could life survive?

      @ arthurr. Gravity is directly proportional to the size of the planet. F=Gm1*m2/d2 where g is the universal gravitational constant, m1 is mass or planet 1, m2 is planet 2 and d2 is the square of the distance between the planets . That's the formula for measuring centrifugal gravitational force between two bodies and it has been proven by our visit to the moon. This is how you can tell the gravitational pull of far away planetary bodies.

      It wouldn’t let me do a normal post so I had to do a reply. %100, have these scientist lost their minds? How in the world can you be so sure? And what’s with this presumption that aliens would need water to survive. We have absolutely no idea what life outside our planet would be like if in fact it did exist. For all we know life outside this plant could be some kind of gas that floats through space, and doesn’t need water or a planet to survive. Humans can be so self absorbed, thinking that life will look or be like us in any way at all. The chances that life would be something so different that we may not even be able to see and understand it are much greater then having life be like us. There are endless possibilities out there so the chances of extraterrestrial life being even close to what we are like is ridiculous. One thing people don’t realize is that we evolved to adapt and form to this plant, not the other way around. This plant was here long before us, and will be here long after us. It’s ridiculous to believe that the entire plant was made just so our little flash of existence can survive on it. Had our life evolved on another planet we would have been a completely different kind of creature, evolved to adapt to whatever that environment would have been. We are made up of water and need it here on this planet because there is so much if it here, we evolved to need it and be a part of it. I think a lot of people are losing their minds. It seems they want to believe in something so bad, they will reach far into the ridiculous to do so.

      blue, they calculate the density of the nearby star using it luminosity (luminosity equals mass to the power of 3.5) THEN they observe the affects of the orbiting planet on the star. By observing the affect (the amount of wobble) the planet has on the star they then calculate the mass of the planet.

      To find the gravity you measure the effect of the movement of the plant compared to the stars and other bodies around it. It is quite possible to calculate the gravity, mass and acceleration of the planets simply by observing their movement and having some frame of reference.

      The science and physics around space travel and exploration are extremely important for humanity. It takes generations to build theories and discoveries that can enable us to leave our solar system. None of us will live to see humans leave this system, but we cannot forsake the R&D necessary to make it happen because of the long time frames involved.
      If humanity cannot leave earth, we will all die here. There will come a time when this planet will no longer support life. That is a hard fact of science.
      I personally hope that physics will give us a way to create some type of interstellar propulsion system than enables travel amongst the stars within a reasonable time frame. If not there are other alternatives to help our species survive, robotic exploration and so called "ark" ships that bio tech will one day make possible.
      The point of this being is that we cannot give up or ignore the great importance of increasing and building on our scientific understanding of our universe and our role as intelligent life in surviving the hostile nature of it.

      Earth's global magnetic field comes from an active dynamo - that is, circulating currents at the planet's liquid metallic core. A similar dynamo once churned inside Mars, but for reasons unknown it stopped working four billion years ago.

      So it is not rotation of the planet itself that leads to a magnetosphere, rather it is internal churning of the core. Without such a dynamo, the atmosphere of mars, and any other planet, may be blown into space by solar winds.

      Actually arthurr, they say it's 3 times the size of the earth but the gravity is similar, you can calculate gravity quite easily by the interaction with other planets; and it IS rotating, like mercury it rotates once every orbit of the sun (a planetary year), hence it keeps one side always facing its star

      in terms of gravity the way they were able to detect this planet in the first place was by measuring the wobble of its star, or in other words, the gravitational effect the planet has on its star makes the star wobble slightly, without the ability to detect the wobble we would have never discovered this, or other, extrasolar planets. there is most definitely a way, if they can measure how much of an effect the planet has on the star, to figure out the strength of the planets gravitational field

      The conditions of the planet ,orbit, and if they have traces of water -will mean that 99.99% it will have life but it could be a microscopic – virus type, The probability that there is intelligent life in the universe is 100% the reason we Have not founded is because we are just starting out- @freeman so no, you are wrong about HUMANITY being important!! It is arrogance to think that- Humans are good at mimic and reproduction- the advances come from a few abnormal Geniuses who carry everyone else forward a tiny fraction- then others build upon this forward leap.

      @arthurr
      Realistically the astronomers can use the following equations given the mass of the star (which we usually know), the period of the orbit of the planet (how long it takes to move around the star which we can tell by Doppler or a decrease in the light emitted sometimes).
      r^3=((G*M)/(4*pi^2))*P^2 where p is the period, M the star's mass, G the gravitational constant and that gives you r, it's orbital radius
      then they use
      v=sqrt(GM/r) where the letters mean the same as before and that gives you v, the velocity of the planet
      then they use
      m=(M*V)/v where M and V are the mass and velocity of the star and m and v are the mass and velocity of the planet. The velocity of the star can be derived from the Doppler if you know the inclination of the planets orbit. Simple as that and you know the mass of the planet.

      said it's three times the size, but less gravity. no specific amount. it's a safe assumption to tell via the fact it's not spinning as fast/faster, approximate density (same way they tell the approximate density of our planet and other planets in the system.) also via the orbit of surrounding celestial bodies and their effects on each other.

      100% chance of microbial life maybe. This seems exaggerated. To all the people who say life could not resemble us? Remember you only get the chart of the nuclides to work with, and the laws of physics to obey. So yes life is probably going to resemble something we would recognize. With the extreme temperatures from tidal lock it is doubtful life would evolve past one cell. Without a moon to vacuum space for us it was probably and still is bombarded heavily from space, so mass extinctions would be frequent. I am calling BS on this article. They probably need funding for a new telescope, which I hope they get. Give them the money for a new space telescope, or maybe a moon based one, come on congress.

      the article says 100% chance of life, i agree because no where does it state complex life, the temperature on surface is irrelevant to the biengs under the crust. For micro organism, or even some type of earthworm if you want multicellular, what matters is the water at this proximity to sun and the atmosphere to protect from radiation, also it orbits a red dwarf, so chances are if there was larger life forms, they would be small compared to earth, because not as much energy coming from the sun to the planet. but all in all i will say THIS IS AMAZING!

Who is to say that life needs water? Or air? Or anything, because what if the extra terrestrials have the ability to turn matter to energy and vice versa? What that means for some of you, is that what if i took a rock, turned it to energy, and thats all i needed for the rest of the day. Not food, per say, nor water. Just any form of matter. Not consumption, conversion. So thank you Sark for bringing your lightned opinion on this rather dreary subject.

    • Nibiru its almost here.

      It's Planet X , none as Nibiru in the Sumarian text, which has a long liptical orbit every 3600 years it comes into our solar system based on the work of Zecharia Sitchin has garnered much attention among ufologists, ancient astronaut theorists and conspiracy theorists. He claims to have uncovered, through his retranslations of Sumerian texts, evidence that the human race was visited by a group of extraterrestrials from a distant planet in our own Solar System.

      Part of his theory lies in an astronomical interpretation of the Babylonian creation myth, the Enuma Elish, in which he replaces the names of gods with hypothetical planets. However, since the principal evidence for Sitchin's claims lies in his own personally derived etymologies and not on any scholarly agreed interpretations, his theories remain at most pseudoscience to the majority of academics.

      Sitchin's theory proposes the planets Tiamat and Nibiru. Tiamat supposedly existed between Mars and Jupiter. He postulated that it was a thriving world in a much differently shaped solar system, with jungles and oceans, whose orbit was disrupted by the arrival of a large planet or very small star (less than twenty times the size of Jupiter) which passed through the solar system between 65 million and four billion years ago. The new orbits caused Tiamat to collide with one of the moons of this object, which is known as Nibiru. The debris from this collision are thought by the theory's proponents to have variously formed the asteroid belt, the Moon, and the current inclination of the planet Earth.

      To the Babylonians, Nibiru was the celestial body or region sometimes associated with the god Marduk. The word is Akkadian and the meaning is uncertain. Because of this, the planet Nibiru is sometimes also referred to as Marduk. Sitchin hypothesizes it as a planet in a highly elliptic orbit around the Sun, with a perihelion passage some 3,600 years ago and assumed orbital period of about 3,750 years; he also claims it was the home of a technologically advanced human-like alien race, the Anunnaki, who apparently visited Earth in search of gold. These beings eventually created humanity by genetically crossing themselves with extant primates, and thus became the first gods.

      Beginning in 1995, websites such as ZetaTalk have identified Nibiru or "Planet X" as a brown dwarf currently within our planetary system, soon to pass relatively close to Earth. Sitchin disagrees with the timing of passage. All will see in 2011 the second sister of our own Sun will be visible by that time the size of the moon, by 2012 to 2013 this planet will distrupt everything possible a pole shift on Earth.

      Sitchin also postulates that Pluto began life as Gaga, a satellite of Saturn which, due to gravitational disruption caused by Nibiru's passing, was flung into orbit beyond Neptune.

      and if life is carbon based then, with a doubt, water is necessary. It's been theorized that other element such as sulfur or silicon could be the base for life and water wouldn't be necessary. However, the relative scarcity of of these elements and the massive abundance of carbon in the universe makes it improbable that other elements would form the foundation of life.

Compare that to how much life there is on this planet. You may change the species or the contruct of the life in a biosphere, but it is pretty hard to extinguish...just think about that when you read these sensational articles about finding another earth that is barely within the habitable zone or basically, in relatable terms, about where venus is from our sun...not to mention it doesn't rotate and the surface temp. is about -12 C...

      Yes, chemical reactions can occur differently in different conditions (i.e. different gravity, atmosphere, etc).

      @Jeff : You're correct, but there's more! While carbon is about 5 times more abundant than silicon in the universe on the whole, silicon is much more plentiful here on Earth. Carbon and silicon both share ability to form 4 chemical bonds at once. However, carbon has a propensity to form double and triple bonds, making it a much more durable base element for life.

      One would think that if it were possible for life to be silicon-based, it probably would have happened on Earth. While we don't know for sure, of course, the prognosis doesn't look good for silicon-based life

I would be very surprised if there aren't lots of planets similar to Earth out there. As scientists keep searching, we'll keep learning more and more. It's premature to say Earth is rare though.

      Probably not that many on the night side, though given what we know about the adaptability of life I'd be surprised if there weren't at least some microbes

    wasn't this planet discovered back in 2007 or was that another Gliese581. either way kepler should find more like these! im excited to know if there are any closer to us!

      That was Gliese 581c. It was discovered in 2007.

      It was 581d. It's in that Goldilocks zone as well. But it's probably a gas giant.

      That other planet is inside the habitable zone too, but it's likely a gas giant

      Course, the gas giant might have a bunch of habitable moons, ones that would not be tidally locked.

      I've said for a long time that the Gliese 581 system has got a *lot* of potential. When we develop unmanned probes capable of going that far, that should be the first place we go.

      I agree. 100% is not "chance" it's certainty! This article is full of contradictions. No rotation means little in the way of seasons, and who can say what the core of the planet is like? If it is not metallic, it likely has no magnetic field, which means little shield from stellar radiation. Not saying there is no life there, just how can anyone be so sure?

      If you read the articles written by scientific blogs and sites it says that the scientist that made those comments was speaking completely out of his own personal idea, and not scientific research. Basicly he was just saying what everyone is hoping. Mass media outlets must just have a max word count they can post or something. Hope it doesn't ruin that scientists career by people passing what he said off as his conclusion.

      Agreed. The scientist should have known better than to say 100%. I am assuming he was just caught up in the moment.

      I think the author is saying that there's a 100% certainty that there's a chance for life. So in other words, it's completely valid to say "there's a 100% chance that there's not less than a 0% chance for life to develop."

      Kidof feels like that statement: "60% of the time, it works every time."

      Saying there is "100% chance of life" is different than saying "100% there is life".
      He just means that he's 100% sure this planet meets all the requirements for developing life, there thus it is 100% that there is a chance of life on the planet. He doesn't advise the probability of life actually having developed.
      Also note that when a scientist says "life", any organism floating around in a puddle would suffice.

      Sam I completely agree. Even the harshest disinfecting chemicals will stop short of the famed 100% The only things that are 100% certain in life are death and taxes my friend. The foolheartedness of that scientist is apparent in his self contradiction, "The chances for life on this planet are 100 percent; I have almost no doubt about it." Almost no doubt ≠ 100% And the necessity for a planet to have a metallic core cannot be understated either. Even the toughest bacteria known to man right now, D. radiodurans, can only survive in 5,000 Gy which is far, far less than the 51,000 Gy the one experiences in space.

      You need to realize that if this planet has condition that's really similar to the earth, then the chance of it having life is extremely high. I would say very close to certainty, because when you really read a little about biology, life is all about chemistry. Biologist had done something very closed to produce "artificial life". Once you put all those elements together, chemistry simply takes over and produce lief. If the conditions are similar, the chemistry that produced life here on earth will do the same on that planet.

      I agree with Brandon - I'm 100% certain that there isn't a 100% chance of life on that planet. The only way to be 100% certain would be to see it, communicate with it, etc.

      It says a 100% "chance", which just means a chance. Now the question is, what are the odds?

    Chances are the first time we see intelligent aliens, it would be only for a brief moment. The reason I say brief is because they'll probably be performing a maneuver in our Solar System called a gravitational slingshot maneuver aka swing-by. NASA uses this all the time here in our solar system. It's when you approach a planet and use its gravity to accelerate, decelerate, or change your trajectory. This maneuver helps save fuel. Virtually all probes we have sent to explore Jupiter, Saturn, Uranus, Neptune actually swung by Venus first to build up speed to reach the gas giants. Theoretically this maneuver could be performed during star travel. It's funny that the first time we see aliens they'll probably just be passing by using our star's gravity to get to where they want to go. haha We would probably be like WAIT! COME BACK!

      For distances within a solar system ok, but for interstellar travel?? No way unless it was some type of generational ship.
      The distances are just to great for traveling at sub light speeds between stars for any type of gravitational slingshot manoeuvre to be useful.
