  5. Resolved Question: Why don't we have pictures of extrasolar planets?
    6. 15 Apr 2008 at 1:09am
    I think its because the stars that the extrasolar planets are orbiting outshine the extrasolar planets, so we can ony view them as a dark circle, can someone confirm this? im not sure, but I think that might be why. Oh so we can't see them simply because they're too far away? thats a shame, i hope we develope technology to prove otherwise soon Ah, Zah it makes some more sense now, so say if i put a 100 watt light next to a 50 watt light, the light being emitted looks of the light from the 100 watt light only, since the 50 watt light is inferior, its like its not there, and since stars produce much much more light than that which is reflected off the planets, it is as if the planet is not there, when u go to look for it. Makes a lot of sense now.


  6. Resolved Question: Religion: Astronomers See 'Youngest Planet'?

  7. Resolved Question: Overlapping shifts of planets?
    8. 4 Apr 2008 at 5:13am
    I am trying to understand an article on 55 Cancri... a statement reads, "Multiple planets imprint multiple overlapping shifts, which require time?and mathematical modeling of possible planetary arrangements?to tease apart." How does an extrasolar planet with a longer orbital period make more difficult to identify due to these overlapping shifts? Can someone explain this in layman terms? 10 points for grabs!! Thanks so much!! (:


  8. Resolved Question: Doppler-shift method in layman terms?
    9. 4 Apr 2008 at 3:52am
    Can someone explain this method in layman terms? It's in the context of the discovery of extrasolar planets.. "The Doppler-shift method relies on the fact that a planet moving in orbit pulls on its star with a gravitational force that changes in direction as the plane orbits. It looks for the variation in the star?s velocity that a planet?s gravitational force will provoke. By observing the repetitive cycles in which the absorption lines in the star?s spectrum shift to longer and shorter wavelengths, astronomers can determine the planet?s orbital period directly, by measuring how long it takes for the changes in wavelengths to pass through a single cycle. Since each star?s spectral type correlates with its mass, astronomers can easily estimate the mass of the star whose motions are perturbed by the planet. The average planet-star distance can then be found." It lost me somewhere in the middle. A simpler explanation, anyone? 10pts for grabs thanks aloottttt!!!!!

  11. Resolved Question: Two questions about life discovered on another planet...?
    12. 26 Feb 2008 at 1:16pm
    Okay, I'd like to present to you two hypothetical situations? We discover with the new high powered Hubble telescope that?s been installed this summer a planet, 3 light years away, about the size of our planet, orbiting a sun, about the size of our sun. These are called extrasolar planets. We also are able to see that there are artificial satellites orbiting this planet and on the dark side of the planet we notice that there is light and electricity. We?re able to signal this planet with a high powered light, some sort of Morse code message saying, ?Come and visit us, we?re peaceful.? Well three years later, a space ship arrives with humans from this extrasolar planet, camera crews are following the space crafts landing. The visitors say something like, ?take me to your leader? and a WORLD WIDE PRESS conference is set up with representatives from all nations are present and the discussion begins. Now, two questions about this sort of story. First, what would happen in our religious culture, if when asked about God, the visitor tells how in their human history, early cultures DID believe in God, but everyone now knows that no such ultimate supreme power exists. That everything was created when an enormous super nova erupted and began this part of the universe. That the universe is vast, far more than our imagines could ponder. That a supernova was caused by gravity pulling everything in the known universe 17 billions years and it reached a breaking point when all of the four natural forces were arranged, gravity, electro-magnetism, and the strong and weak nuclear force. The visitor also verifies Darwin?s theories and concurred that life on our planet formed the exact same way on their planet; and on many of the life carrying planets in the cosmos. There was no creator or sustainer but the belief in God was simply a way for the human mind to explain the unexplainable. Now question two, What sort of impact on the Non-religious culture would be when asked about God, the visitor tells the Genesis story, he explains how a man named Jesus Christ came down from heaven and died on a cross for the sins of humanity. Suppose they also had an uprising of Muslims and that there are a few other religions on their planet but the majority of people are Christians. What if he validated everything the bible says to be true, that God was the creator and sustainer of all human life, outside of our space and time? Can one person be impartial to both sides to be able to answer these questions un- biasedly?


  12. Resolved Question: Evaporating planet? How?
    13. 5 Feb 2008 at 3:47pm
    Planet HD 209458b is evaporating. It is so close to its parent star that its heated atmosphere is simply expanding away into space. Some astronomers studying this distant planetary system now believe they have detected water vapor among the gases being liberated. This controversial claim, if true, would mark the first instance of planetary water beyond our Solar System, and indicate anew that life might be sustainable elsewhere in the universe. HD 209458b is known as a hot Jupiter type system because it involves a Jupiter-type planet in a Mercury-type orbit. Although spectroscopic observations from the Hubble Space Telescope are the basis for the water detection claim, the planetary system is too small and faint to image. Therefore, an artist's impression of the HD 209458b system is shown above. Research into the atmospheric composition of HD 209458b and other extrasolar planets is continuing. I just read this online, and was wondering, how did astronomers detect water vapor? Thanks.


  13. Resolved Question: NASA, ESA joint project, and your tax dollars?
    14. 5 Feb 2008 at 12:18pm
    If NASA, the ESA, Japan, India, China, and all other space- faring nations were to announce their intention to launch a space- based interferometer, able to actually SEE extrasolar planets orbiting distant stars, would you be FOR it, or AGAINST it? If the money in the related government coffers wasn't there to fund this type of project, would you, as an individual, volunteer to donate MORE money toward making this project a reality? Would it be (personally) worth it to you? Would you pay HIGHER taxes, if there was a guarantee that this extra money would actually be SPENT on that project? OK allow me to clarify... IF this interferometer was sensitive enough to not only image the planet, but possess enough resolution to ultimately break down the atmosphere (spectroscopically), would you volunteer more bucks? Remember, "No bucks, no Buck Rogers"! Would you all back it?

    17. 25 Jan 2008 at 2:49pm
    Planets Around Other Stars (1995 ? 2004) Astronomers find a host of extrasolar planets as a result of improved telescope technology and prove that other solar systems exist, although none as yet resembles our own. Astronomers are able to detect extrasolar planets by measuring gravitational influences on stars.

  17. Resolved Question: Colonizing extrasolar planets?
    18. 18 Jan 2008 at 6:01pm
    When and how do you think mankind will colonize worlds beyond our solarsystem, if at all? I know its daunting task.We will likely at least establish science colonies on Mars and possibly Titan or Europa, or some other Jovian moon. But what about beyond this solar system? We'd almost have to have some means of traveling faster than light to make it practical within a single human generation. But with cryogenic stasis and genetic engineering we may be able to enable humans to travel while frozen. These people may also have gone through gene therapy to extend their live spans. Of course we need to find a new world to move into first.


  18. Resolved Question: If you could privately launch an interferometer...?
    19. 9 Jan 2008 at 9:06pm
    If you could launch, through a private agency, an interferometer that would have a resolution 1000x the HST's, would you provide the funding for it? Even if you would have to put up everything you owned (and then some), for the sheer thrill of discovery? To actually SEE extrasolar planets, stars births as never before seen... Would you do it? Remember that a launch failure or catastrophy would financially ruin you, and you may spend the rest of your days in a refrigerator box... I'm curious... how many of us love science SO much, we'd be willing to stake everything we had in order to see it move forward? OK... Let's assume that everything was engineered, tested, and approved by the highest of authorities, experts in their perspective fields... Yeah, OK, blah, blah, blah... WOULD YOU DO IT? An interferometer doesn't have to be big... It could consist of 10, 50, or even 100 small telescopes operating on the same target at the same time... To achieve a diameter of 100x the HST's mirror, you'd only need 100 x 3 meter telescopes... Imagine the possibilities...


  19. Resolved Question: Is it possible to send radio signals to extrasolar planets?
    20. 9 Jan 2008 at 8:30pm
    What happens when man made radio signals leave the Earth? I'm curious if our radio signals reach extrasolar planets. Also wondering if it is possible to direct specific signals to reach a target light years away with prediction of position. Thanks! Radio waves dissipate just as light waves do. So how far before a signal traveling through space has lost its original message and is static.

  23. Resolved Question: Have you ever been to HD 209458 b ?
    24. 5 Dec 2007 at 8:05pm
    Thats right TT8 P.E.N.F.O.L.D is from there. Actually his Parents are from Ogle-TR-56b . HD 209458 b is an extrasolar planet that orbits the Sun-like star in the constellation Pegasus, some 150 light-years from Earth's solar system, with evidence of large amounts of mud. After a decade of research as a professional counselor and clinical hypnotherapist, Franfurt's Ludwig Böttger says that there is now enough evidence to conclude that these ?beings? appear to come from other planets and other dimensions parallel to our own. As we have now evidence of some "Visitors" like the now defunct TT8 P.E.N.F.O.L.D which is still to be rumored to have a existence in the UK. It has also to be concluded that some twit fed him after midnight and got him wet.

  25. Resolved Question: Aliens question?
    26. 2 Dec 2007 at 11:53am
    Seeing as there are 400 billion suns in our galaxy, the milky way, and literally billions of galaxies that contain billions, sometimes trillions of suns, like 'm87' in virgo. I believe it is inevitable that we will discover life on extrasolar planets. However, our star, the sun is a middle aged star, what would happen if we encountered a species that were more advaced than us? Could we really cope with what we would find? Or would it be too strange? Imagine a species that has a billion year head start over another species. What do you think? What do you think we would find?


  26. Resolved Question: 2 astrophysics questions?
    27. 25 Nov 2007 at 6:23am
    1. Basic question I have regarding detecting extrasolar planets: It is my understanding that one way we detect "planetary" bodies is indirectly by observing the "wobble" in the the closest start. I am puzzled because while a "wobble" may indicate gravitational force from a planet, it wouldn't indicate much else. As we know the amplitude of the "wobble" would be determined by at least 2 factors, namely the size of the planet orbiting the star and the distance between the star and the planet. Since these are two variables, how could we determine the size of and distance of the planet? My guess is that you also evaluate the period of the "wobble", but that is my guess. Also how could you be sure its a planet causing the wobble since it could be a collection of asteroids for example. 2. Are other universes an accepted "fact" according to modern physics? Do they have the same or different physical laws/constants?


  27. Resolved Question: What you think of Gliese 581 c?
    28. 20 Nov 2007 at 12:23am
    It's a new planet that was discovered about 7 months ago. It is an extrasolar planet (meaning it is not in our solar system.) It, however, does orbit a smaller star than our sun but its small distance makes it a place just like earth, habitable. It's temperature is thought to be VERY close to that of our planet. The only problem is that it's 20 light years away from us which is impossible to get to, at least for now. You guys think we'll ever get there? And you think there's intelligent life on it?!!


  28. Resolved Question: What are the chances of finding a planet that could suppor...
    29. 30 Oct 2007 at 5:52am
    In the search for extrasolar planets that could support life. Scientists state the planet must be in the 'Goldilocks' zone - i.e. not to near and not to far from the planet's sun. So the temperature of the surface of the planet is in the correct range to allow for the presence of liquid water (one of the main requirements for life). My question is what are all of the other requirements that have to be in the 'Goldilocks' zone to allow for the development of life. Such as Gravity, Oxygen levels etc etc.etc. and what are the chances of this occuring?

    46. 29 May 2007 at 10:01pm
    I watched the Science Channel documentary call If We Had No Moon. It shows the moon is important to our planet since it stabilizes Earth's axis. Without it, the Earth axis would become chaotic. So here is my question, does a Earth-like planet need to have a moon? What's the probability of finding an Earth-like with a moon and is on the habitable zone? The moon does more than does that though, what. If you ever watch the documentary, a scientist did a model of the Earth with it's moon and without, the Earth axis was crazy. Tham, how about Gliese 581 c which an extrasolar planet orbiting a red dwarf star. That planet sits on the habitable zone? It's 20 light years away. Here is a link with the Earth I found in Yahoo Answers in regards to Earth with no moon. http://answers.yahoo.com/question/index;_ylt=Atn.g65ZuetvSz24W0ijqu4jzKIX?qid=2006112 9141919AAjd9YB

    47. 29 May 2007 at 2:22pm
    To date there have been 238 exoplanets "published." These planets have been discovered by observing the gravitational "wobble" of their parent stars. If the scientists get REALLY lucky and the planet is orbits on a line of sight between earth and its parent star, we can then determine, roughly, what the planet is made up of. So my question is, with interest continually growing in extrasolar planets, how long will it be before we start seeing this planets through advanced telescopes? Is it even possible to pinpoint planet sized objects that far away? Or is it a matter of getting in line to use Hubble or other telescopes?
