      Ever notice how all the small planets are rocky and all the large planets are gassy? This is not a coincidence. Jupiter and most likely the rest of the gas giants have solid cores, larger in fact than the earth, but due to their immense mass, they have an extremely dense atmosphere, which could not support life, at least as we know it.

      As for smaller planets, you end up with situations like Mars. Mars has an atmosphere, although it has less than 1% of the air pressure that Earth has. .1% if I remember correctly, but don't quote me on that. The gravity of the planet is insufficent to maintain a signficant atmosphere. Atmosphere "leaks" off into space all the time, even on Earth. This lack of atmosphere creates several problems. First, breathing would be extremely difficult, so life forms that DO exist would have to sustain themselves on very little air. Meteors would also present more of a problem, as they can't burn up as easily.

      Venus has sufficient atmosphere, but its proximity to the sun, as well as the contents of its atmosphere, creates an environment that's too hot for "conventional" life to survive.

      Of course, you also have the issue of habitable zones and their relation to the size of the sun. Consider our solar system as one that works. We're not too close, nor too far away from the sun, and the sun has 10 billion years of life (half of which it has expended already). Say we're looking at a larger star, like a blue giant. The planet could orbit further away and maintain the same temperate zone, but in 10 million years that sun is going to go supernova and any life will have not had enough time to evolve from inception. It took longer than that just for the Earth to cool down.

      Large planets orbiting close to the sun present a problem. The primary concern is how they got there. Chances are good that they didn't form that close to the star, but formed further out then migrated inward to their present positions. If this is the case, its a darn good chance that any planets within the habitable zones will have either collided with the gas giant or been kicked out of the solar system.

      The lack of any gas giants is also a problem. Jupiter does a nice job of attracting and "removing" potential threats to Earth, mostly the very large rocks. Without the gas giants out there to help us out, the Earth would get battered far more frequently than it does. Life can handle a huge hit once every 60 million years or so. Long term evolution would be severely hampered, however, if it happened more frequently.

      A potential alternative to the current solar system is a gas giant located in the habitable zone with a earth sized moon. The moons of Juipter would have a significantly more viable climate if they were orbiting at 1 AU. However, this would present other dificulties, namely tidal lock. The moon would have to be sufficiently close to the planet so it didn't roast any one side for any significant length of time, however, the planet itself would block the light to the moon, so the moon would have one side that was perpetually frozen and the other side that had to endure long days and long nights. And any moon close enough to the planet to orbit quickly enough would have severe tidal problems... think IO.

      So anyway, our best bet... is to find a solar system that resembles ours. At least until we find another model that works. Sorry about the extended rant.

    A team of astronomers announced today the discovery of the first planet outside our solar system with an orbit similar to Jupiter's, a configuration that has the potential to support an Earth-like planet.

    They also found the least massive world ever detected around another star, a planet just 40 times as heavy as Earth.

    The primary discovery is a gas giant planet that circles a star called 55 Cancri every 13 years, comparable to Jupiter's 11.86-year orbit. The planet is between 3.5 and 5 times as heavy as Jupiter.

    "It's the first extrasolar planet that reminds us of a planet in our solar system," lead researcher Geoffrey Marcy said in an interview with SPACE.com several days prior to the announcement.

    Marcy, of the University of California, Berkeley, said he and colleague Paul Butler, of the Carnegie Institution of Washington, have dreamed of this discovery for 17 years as they compiled data using a technique that many scientists said would never work. The two astronomers, whose team has grown in recent years, also announced 11 other worlds today at a press conference at NASA headquarters, bringing the total of known extrasolar planets to 98.

    Potential for Earth twin

    The new planet orbits 55 Cancri at 5.5 astronomical units (AU). One AU is the distance from Earth to the Sun. Jupiter orbits at 5.2 AU. The same team had already spotted another planet around 55 Cancri, a place slightly less massive than Jupiter. It orbits so close to the star that it makes a complete orbit in just 14.6 days.

    Marcy speculated that the two-planet system could harbor more intriguing worlds, possibly even rocky planets like Earth, known as terrestrials.

    "A Jupiter at five Earth-Sun distance units might serve as the marquee of a planetary theater located within, where terrestrial bit players are racing around on smaller tracks," Marcy said. "We are left to imagine what geophysical and perhaps biological improvisation is taking place inside this planetary playhouse."

    Armed with their new data, Marcy and Butler enlisted theoretician Gregory Laughlin of the University of California, Santa Cruz, to look into whether the 55 Cancri system could also retain an Earth-sized planet in a life-sustaining orbit. Such a region, called a habitable zone, would maintain moderate temperatures suitable to the retention of surface water and the possibility of life.

    Laughlin ran the data through computer models of planet formation. The answer is "yes."

    "We tried a hypothetical configuration of a terrestrial planet in the habitable zone around one AU from the central star and found it very stable," said Laughlin, who also is associated with Lick Observatory. "Just as the other planets in our solar system tug on the Earth and produce a chaotic but bounded orbit, so the planets around 55 Cancri would push and pull an Earth-like planet in a manner that would not cause any collisions or wild orbital variations."

    Marcy and Butler caution, however, that there is no way to detect an Earth-sized planet with present technology. Meanwhile, their data does suggest a third planet in the system, a possible Saturn-sized object. Others could lurk there.

    Laurance Doyle, a researcher at the SETI Institute who was not involved in the discovery, told SPACE.com the new finding "is a strong encouragement" that our solar system "may not, after all, be totally unusual."

    The Jupiter-like planet has another potential benefit, Doyle points out: Its gravity would lure comets, shielding inner planets from life-threatening bombardment. Jupiter plays this protective role in our solar system.

    Pushing the limit

    Marcy, Butler and their colleagues also announced today the lightest extrasolar planet ever found, one 40 times as massive as Earth.

    This discovery pushes the lower limits of their wobble method, which spots movement in a star induced by the gravity of an orbiting planet. (No confirmed planet outside our solar system has ever actually been photographed.)

    This relatively small planet, whose possible presence was first reported in May by SPACE.com, was detected around a star called HD 49674. It is just 15 percent the mass of Jupiter. Theory holds that it would be gaseous, not rocky. Previously, the lightest known extrasolar planet was more than 50 times heavier than Earth.

    For comparison, Neptune is about 17 times as massive as Earth and Saturn is about 95 times as heavy.

    Marcy has said the wobble method will not be able to find planets weighing less than 10 Earth-masses.

    The SETI Institute's Doyle uses a different method for planet hunting, however. He looks for slight dips in a star's light that indicate the passage of a planet. The method has yet to discover a planet, but it has been used to detect the atmosphere of a known extrasolar planet.

    This so-called transit method could spot a planet twice as big as Earth, Doyle says, if the planet's path is properly aligned so that it passes in front of the star as seen from Earth.

    Such a planet would have roughly eight times the mass of our own. It would still be rocky and could, theoretically, harbor life.

    Doyle said the existence of two planets bracketing the habitable zone around 55 Cancri "indicates that planet production may have taken place within the habitable zone of that system."

    Dream come true

    The discovery of the Jovian twin caps 17 years of planet hunting by Marcy and Butler, who were not deterred by early skepticism in their technique.

    "Way back in 1985, Paul Butler and I began sketching the idea for a new instrument, attached to a telescope, that might someday detect planets around other stars," Marcy told SPACE.com. "Some very smart people told us that we wouldn't succeed, that we would never detect the wobble of a star caused by its attendant planets."

    They did, beginning in 1995 just months after a European team found the first planet around a star besides our Sun. Marcy and Butler confirmed that finding and went on to become the world's most prolific planet-hunting team.

    "We always dreamed that maybe, with a wisp of phenomenal luck and dogged perseverance, we might capture evidence of a Jupiter-like planet," Marcy said.

    Prior to today's announcement, all known extrasolar planets orbited more closely to their host stars, some as close as Mercury is to our Sun.

    Because the planet around 55 Cancri takes 13 years to make a complete orbit, it took equally long for enough data to accumulate to definitively identify the object. Its orbit is elongated instead of being nearly circular like Jupiter's. "We haven't yet found an exact solar system analog," Butler said. "But this shows we are getting close."

    Other recent discoveries have shown that circular orbits do exist around other stars.

    Butler said more Jupiter-like planets will likely flow from the data they are collecting on 1,200 Sun-like stars.

    What's next

    While Doyle or someone else might find a planet twice the size of Earth, the discovery of a true Earth-sized planet won't come for at least a few years, most researchers agree.

    But now there is a perfect place to look.

    The 55 Cancri system "will be the best candidate for direct pictures" by a next-generation space-based observatory, said Debra Fischer, a UC Berkeley astronomer who is part of the Marcy-Butler team.

    Two such missions are planned by NASA, first the Space Interferometry Mission and then the Terrestrial Planet Finder. The discovery of a solar system with elements similar to our own "adds urgency to missions capable of detecting Earth-sized planets," said Charles Beichman, NASA's Origins Program chief scientist at the Jet Propulsion Laboratory in Pasadena.

    No firm launch dates are set for either of these satellites, however. Both would follow the less ambitious Kepler mission, set to launch in 2007. Kepler will use the transit method to detect and generate a census of Earth-like planets around other stars, assuming such planets exist, but it won't photograph any.

    Details of the research

    The star 55 Cancri is in the constellation Cancer. It is roughly 41 light-years from Earth and about 4.7 billion years old, comparable to our Sun.

    The new discoveries were funded by NASA and the National Science Foundation. Observations of 55 Cancri were made at the Lick Observatory. The Anglo-Australian telescope was used to find two of the other planets announced today.

    Other scientists who collaborated in the new findings: Steve Vogt, UC Santa Cruz; Greg Henry, Tennessee State University; Dimitri Pourbaix, Universite' Libre de Bruxelles; Hugh Jones, Liverpool John Moores University in the United Kingdom; Chris Tinney, Anglo-Australian Telescope; Chris McCarthy, Carnegie Institution of Washington; Brad Carter, University of Southern Queensland, Australia; and Alan Penny of the Rutherford Appleton Laboratory in the United Kingdom.

    The wobble method, which is so far responsible for all extrasolar planet discoveries, is also known as the Doppler technique. The researchers employ special filters in a telescope to measure a change in the wavelength in light coming from a star. The change results from the star moving toward the telescope and compressing the waves, and then moving away from the telescope and lengthening the waves.

    The effect is similar to the change in sound of a siren from an ambulance rushing toward you and then heading away.

    Currently, they have 2 ways (that I'm familiar with) to find an extra-solar planet. First, they can look for a "wobble" in the path the star takes. This wobble is caused by the gravitational pull of a large planet orbiting the star. Earth is so small that the tiny wobble caused by a planet similar in size would be impossible to view; or at least it would disappear with the systematical error.

    The other way I've heard of to find extra-solar planets is similar to an eclipse. When the planet comes between the star and Earth, we can measure the changes in luminosity of the star. Obviously, with planets with small orbits, we can determine how quickly the planet orbits the star because of the pattern in the luminosity. Again, we can't detect earth size planets since earth is just too small.

      Historically, the idea that we are somehow special and priviledged has not held up very well. Now of course, we only have one example to work with, but there are several indicators that life is not an aberration. Of course, you can invoke the anthropic principle and argue that we wouldn't be commenting on the matter if we weren't here. But there are a number of problems with that. First, intelligence clearly is relatively unusual (most life forms on the globe are not intelligent, and during most of the history of life on earth there were no intelligent life forms). So for life to be an aberration, you have to assume that we have the benefit of *two* improbable events. But wait, it gets worse. Life clearly appeared very early in the history of the earth. Statistically speaking, the average "waiting time" for an improbable event should be long. So if life is improbable, our planet was not merely remarkably lucky to get life at all, but remarkably lucky to get life so early.

      So the argument that life is improbable requires the assumption that we were extraordinarily lucky in three different ways: 1) lucky enough to get life at all, 2) lucky enough for it to form early rather than late, and 3) lucky enough to develop intelligence enough to comment on it.

      Finally, life is not extraordinarily delicate. It is found everywhere on the planet. Indeed, I don't know of anywhere that one can say with scientific certainty that life is absent. No, a given life form will not survive in conditions drastically different from those to which it is adapted.

    Planets larger than Earth will tend to have super-thick atmospheres with very hostile environments (e.g. the smaller gas giants, and Venus). Notice Venus in this list - an Earth-sized planet has a gravity well deep enough to hold an inhospitably thick atmosphere. Only some quirks of Earth's formation and evolution (mainly the presence of the moon) give us an atmosphere thin enough to let our type of climate and our type of life exist.

    Life could exist deep underground in a much wider range of planets, but this would be microbes and not much else.

    Life could potentially exist in oceans under the frozen crust of smaller worlds (e.g. Europa), but would likely be less interesting than life on Earth-like worlds, due to a much smaller energy throughput. These worlds would also have to have a substantial source of heat (either radioactive, like Earth's, or tidal, from being a satellite of a larger planet) to avoid freezing solid. Larger worlds will probably have enough geothermal energy to churn up their oceans, making stable life-bearing layers less likely.

      While I agree with the article's assertation that plate techtonics are needed for a hospitable environment, I think its logic is suspect when discussing the moon's role in the formation of our own.

      The thickness of the crust is relatively insensitive to mass being magically added or removed - it's a result of the rate of heat generation in the core and the thermal properties of the mantle. As the core's heat conducts outwards, you get a temperature gradient set up. The outer surface of the planet will be at or near the blackbody temperature needed to radiate this heat into space at the rate it's generated; the lower boundary of the crust is at the point where temperature has increased enough for rock to be pliable (not necessarily molten, for the upper mantle).

      If you were to take the moon apart and coat the earth with it, the thickness of the crust wouldn't change - you'd get the lower parts of it being absorbed into the mantle.

      Plate techtonics are the result of the mantle's equivalent of climate. As there's a heat gradient in the mantle, convection currents are set up that move material around. As the Earth is spinning, you get a complicated pattern of currents set up analogous to the "trade winds" in the atmosphere. These mantle currents drag bits of the solidified crust with them, resulting in the plate motions we're all familiar with. As long as the crust is thin enough to be moved, this will occur (and I established above that its thickness is fairly insensitive to more or less mass being added, as long as the Earth's radius doesn't change by a substantial fraction).

      Lastly, the article implies that the moon was formed from ablated crust material. This is not strictly true. The original impact (of a Mars-sized body) would have disrupted both the crust and the mantle, ejecting a vast amount of material, most of which either permanently escaped or fell back to the Earth. Only a relatively small amount stayed in a stable orbit and coalesced into the moon. The Earth had to re-form its crust from scratch after this event - so the post-moon crust would have had pretty much the same characteristics as the pre-moon crust.

      In summary, I think that it's the Earth's gross size and rate of core heat generation that determine whether or not it has plate techtonics, not the presence or formation of the moon.

      Gravitational perturbations are due to differential gravitational forces, and the forces on Earth due to a planet orbiting at 0.025 AU are trivial. As for asteroid components, it depends on how the planet formed, which we don't understand yet. If it formed far out, and moved in, then yes, it would be a menace. But if it formed close in, it's extremely unlikely to cause any "asteroid bombardment" or anything like that.

      As a fundamentalist Christian, and an ordained Southern Baptist minister with an MS in Software Engineering, I'd be happy to offer my thoughts on your question.

      First off, I would agree whole-heartedly with the previous poster who commented that much depends on whether the life discovered was (is) intelligent, and whether or not it has a soul.

      As far as what I think about stories like this... I don't find any conflicts between my faith and these kinds of articles. The Bible makes mention of creatures such as the Nephilim who lived or visited Earth prior to the flood. And any Christian who would take the time to thoroughly study the Bible would be compelled (I think) to conclude that there is much that we don't know or understand about our situation in the grand scheme of things. If you're going to accept that there are angels, seraphim, cherubim, demons, etc... then they, by definition are "extra-terrestial." I do believe in a Creator, and that Jesus Christ was the Creator incarnate. Simple logic would lead one to believe that if He created life here, he could, at His discretion, have created it elsewhere. (One reason I run seti@home, just out of curiosity)

      A thorough study of the Bible must entail at least a passing familiarity with the language(s) from which the version you're reading was translated. The gospel of John tells us that Jesus Christ died for the sins of the world. (...For God so loved the world...) The Greek word which was translated "world" is "kosmos: the world, the universe."

      Like others, I'm saddened to find Christians, or for that matter, anyone, who seems to cling to the belief that they have the final answer to any question. From the Pope on down, none of us can pretend to even begin to comprehend the magnificence of God. Therefore, when I see articles like the one we're discussing, it thrills me to see that we've uncovered one more small piece of the mystery of God's creation.

      One final note, I've had bad experiences with fundamentalists just like others have. Any group of people will have their lowest common denominators. Scientists can be just as dogmatic about their theories as many zealots are about their theology. Read / study the Bible for yourself, and draw your conclusions.

      Well, whatever they think... fact remains, there are planets orbiting other stars, and they've found at least one with an athmosphere. If they don't like it, they can do what they do with other science that goes against their belief system; close their eyes and hope it will go away.

      I ask becuase, in discussions with Christians, I've heard Christians tell me that there is no intelligent life on other planets.


      As far as I know, noone knows whether this is true or not. Saying that there is or is not alien life, and being very sure when there is no clear evidence in either direction, is not any different from being very sure when saying there is a god when there's absolutely no evidence.

      So I've often wondered what Christians (particularly Christian nerds, who are probably significantly more friendly to science than some of the Christians I've met) think when stories like thit surface and hint at the possibility of finding other "Earth-like" planets that may have intelligent life on them.


      Well, I for one am glad that this is not the mideavals or the dark ages, where the church had all the power and intended to keep it that way, by punishing, for example, scientists that dared to make discoveries and even publish them.


      So, what if the scientists discover life and even intelligent life on other planets? What will happen, especially if christians can't stand the truth? Will they try to stop schools from teaching these new findings, as they are trying with various success stop the teaching of evolution, and before that, tried to stop Galileo Galilei to publish his book where he describes how the earth is orbiting the sun and not vice versa?



      Science can never be blasphemous even if there IS a god. I am pretty sure that a god that created us would let us see the universe he created, for would that not be flattering him; trying so hard to see it all? Aren't christians (or other religious ones) always talking about the Truth? Then why not let us see the truth?


      If there is a god, he has never tried to stop us from seeing his creation - only human beings that are arrogant enough to claim to have some sort of directions from, and communication with god has ever tried to stop it. Never let them do that.

The migration is slow enough that you are almost guaranteed a close-enounter of some kind. Once a Earth-sized planet gets near a giant planet, the orbit is in the very least highly perturbed. Odds are fair that it could be ejected altogher or will collide with the giant planet and be effectly lost. But even if it isn't, the eccentricity is probably going to be increases substantially.

Exploring space is already the biggest adventure mankind has ever embarked upon, and why would we want to wreck the excitement by meeting extraterrestrial life we already know everything about? Wouldn't we want to be able to learn something completely new?

    Why are so many people trying to spell "dimensional?" What's the big draw all of a sudden? Or are you just attracted to anyone talking about a dimension? But to answer your question, yes, I think Slashdot has been taken over by fifth graders. Well, maybe everyone just thought it would be a better idea to drop out of school after the fifth grade and get certifications to appear more desirable in the job market... ;)

    Uh, isn't that definition sort of bending the truth of the situation with regard to the differing opinions of the various Protestant churches? There' nothing wrong with finding points of commonality: but I don't see the point in wiping away differences with a pat definition that simply ignores them.

    Isn't that, well, a little uninquistive, not to mention self-centered? Certainly, what we know and can deal with, and have moral obligatins to deal with, are more important. But that hardly makes the possible existence of alien life uninteresting or meaningless. It could well have very real impacts on life here: how we see ourselves and hte universe around us.

    Generally, I think it to be bad form to assume the position of your fantasy opponents, and speak for them so you can knock down your own utterances.
    While I am not a believer, I also don't think that people who happen to feel that they a have personal knowledge of God, and are following their hearts on how they understand certain aspects of him, deserve ridicule or pre-emptory challenge. Plenty of even literalist Christians are quite humble in their own free admission that they relaly know very little about what they believe to be god's Creation. There's no need to paint all literalists with such a broad brush.

    And I think it's exceedingly cool. I strongly suspect that there is life in many different places and some of that life is probably intelligent and self-aware.

    Do I think that Jesus died for intelligent life on other planets? No, I do not.

    If God has plans for these beings, God is going to reveal it to them in a way appropriate to their nature.

    "Me, my salvation, my personal goals." It sounds a bit self-centered, don't you think?

    Well, then it is. But that's just me and how I am.

    My question made you feel like getting into a debate? Why are you so defensive?

    Aren't all the comments here on Slashdot, especially on stories like this, a huge debate? It's neither right nor wrong, and no one knows for sure. You might think that I'm being defensive, but actually I'm just being frank and letting you know that I'm not interested in discussions which I think will lead nowhere. You're more than welcome to have different views.

    I think this statement really demonstrates the flaw in your thinking. I'm not looking for "the answer" and I certainly don't think it's going to be found in the bible. I can argue capably and scripturally that the bible raises many more questions than it answers. What I was asking for were opinions from Christians, not answers. You don't have "the truth" and you are not obligated to give "God's answer" any time a question comes up. All I really wanted was opinions.

    I'm not saying that that site has *the* answer and all that. In a way, the guy who wrote that site is also just stating his opinion. It's just that he probably made up his opinion based on more research than I did, so I just wanted to point it out to you. As for me, I'd rather form my own opinion only after doing the proper research, and not believe anything just because other people "say so." But this issue is something I'm not particularly interested in, so I'm not going to spend my time and energy researching this. So my opinion is: I don't believe in aliens out there, but I don't really care. But again, that's just me.

    Unlike many atheists you may have met, I respect the dignity, inherent worth, and thoughts of Christians. I believe it's called, "Hate the Christianity, love the Christian." ;)

    I appreciate that. There are many atheists out there who absolutely do not want to have anything to do with Christians or Christianity. But I did not consider you to be one of those at all when I read your post. In fact, I don't have problems with atheists and non-Christians. I'm not one of those who'll push Christianity down your throat. I treat everyone fairly. Even if a Christian asked a similar question to yours (the follow-up question I mean, where you let me know that the site is not what you're looking for), I would've answered the same way.
