Rogue Brown Dwarf Lurks In Our Cosmic Neighborhood

Posted by Soulskill on Friday April 9, 2010 @08:20AM from the brown-dwarf-rogue-lurks-in-ironforge dept.

astroengine writes "The UK Infrared Telescope in Hawaii has discovered a lone, cool brown dwarf called UGPSJ0722-05. As far as sub-stellar objects go, this is a strange one. For starters, it's the coolest brown dwarf ever discovered (and astronomers using the UKIRT should know; they are making a habit of finding cool brown dwarfs). Secondly, it's close. In fact, it's the closest brown dwarf to Earth, at a distance of only 10 light years. And thirdly, it has an odd spectroscopic signature, leading astronomers to think that this might be the discovery of a whole new class of brown dwarf."

  Theoretically possible using a nuclear power source and ion propulsion. Probably would be decades before we could practically do it, but the idea isn't outside the realm of possibility starting with existing technology...
  It'd be a lot easier though to try this with Alpha Centauri though. It's only 4 light years away, not 10.
  This is an interesting find though. Given the lack of planets or sign of the remnants of the formation of a star/planetary system I'd say this thing is definitely a rogue, that formed in another planetary system that was ejected by gravity. Brown dwarfs actually are able to do deuterium (lower mass ones) and even lithium fusion (higher mass ones) for a short period of time (100MY or so for the fuel to run out) but this one may be too small to have done either.
  We certainly are going to discover a lot more of these as we get better and better instruments. They are likely very common, and we are likely to see the discovery of tons more brown dwarfs and very low mass red dwarfs in the coming decades. What is fascinating would be to know exactly where the line is between a very low mass red dwarf that can initiate and sustain core hydrogen fusion and a brown dwarf that either never starts core hydrogen fusion or cannot sustain it.

  True, but not particularly important. Most of the benefit of the "launching lasers" you get by getting up to a high speed fairly soon, reducing your time of flight. If you're only (or largely) powered by launching lasers and solar sails, then you'll be expecting to have an asymmetric journey in both distance and time, because the high intensity of the "launching lasers" at the Sol end of the journey would need to be counteracted by the lower intensity of the light from the target star over a longer distance and duration.
  
  Using an interstellar laser to push it isn't really practical as at those distances it becomes horribly difficult to aim the laser with such precision. Assuming your laser could aim precisely, by the time you realise you are pointing in the wrong direction and make a correction, it will take years for the correction to take effect, by which time the sail has already moved.
  Your laser will have a certain divergence of beam, due to manufacture errors. As you get further away, the intensity will drop (this is part of the reason that you get up to speed as soon as possible, and will, indeed eventually the "launching lasers" will become useless. But regardless, you don't steer the ship by moving the laser, you steer it by tilting the sail.
  With a solar sail, you get two types of drive. Some drive is from particles of solar wind travelling (more-or-less) radially out from Sol hitting the sail and sticking. These transfer their momentum vector directly to the sail, and hence to the towed payload. Their impulse on the sail will always be radial to the target star (to moderate precision). The other source of drive though is from photons that hit the sail and are reflected from the sail's surface. These, as a moment's consideration will tell you, will provide an impulse vector to the sail (and hence, to the payload) which is in the direction of the bisector of the angle between the direction of the incoming photon and the direction of the outgoing photon. In short, the sailor can "tack" his vessel against the light-wind from the "launching lasers". The control system is at the sailor's end, not the launching laser's end ; the launching laser jockey simply points his laser at the target star and leaves it up to the sailor to stay within the beam ; the sailor has to work out how to make the final cruise form the light beam to the target star, knowing that an error either kills everyone on board, or means an unnecessary year in the tin can (which is also likely to be a death sentence for the erring sailor).
  Byproduct : if a solar sail powered probe is launched from star A to star B, then for a number of years before the arrival of the probe at star B, there will be an intense, monochromatic source of light shining from star A at star B. In short, a very bright warning light.
  Reference reading : " The Mote in God's Eye (Orbit Books) (Paperback) by Larry Niven and Jerry Pournelle (Author) ; classic hard SF.
  Byproduct 2 : if your solar sail-powered craft approaches the target star without being greeted or communicated with ... then the inhabitants are either dead, or live underground, or have yet to learn to bang the rocks together. Or just possibly use visual pigments that work in a very different part of the spectrum to your launching lasers.
  Hmmm : multi-wavelength launching lasers. Possible? Helpful? Problematic? I'll have to think about that.

Though our meanings of "love" are probably more-or-less congruent. I see your "long time" and wonder if the duration would really be noticeable.
  The process of putting the bigger and bigger telescopes progressively further and further away will of course give us experience in several incrementally important technologies : those of making and moving big things in space, and those of keeping people in a habitable environment in space for longer and longer periods of time. By the time that we're putting the third Outer Kuiper Telescope in place, each one of which involves sending a ten-person crew on a three year mission to the outer edge of the Kuiper Belt, then the prospect of sending ten consecutive thirty-person trips on thirty year missions to Proxima Centauri would appear considerably less daunting.
  The interstellar trip would appear even less daunting if they knew that two ten-person inhabitation modules (a standard design, with a hundred-year proven working life) had arrived and gone into a parking orbit at Proxima, and that another four modules are in flight, due to arrive before they do with additional ones being launched every second year thereafter until Proxima Colony tells Old Home Terra to stop throwing tin cans. The automated solar cell (hmmm, that name will have to change!) factory might also be in flight, so the first things to do on arrival at Proxima would be to collect several gigatonnes of iceballs for reaction mass (just like refuelling the reactors for the Outer Kuiper Telescope), and then settle down to breeding and building another asteroid civilisation. Planets? Well, if there are any, they might get colonised one day, but the important things would need to be done first. After all, terraforming is really hard, and it's hard to envisage how the original Earthlings did it without modern technology.
  The technologies necessary to real long-distance space travel are far more likely to appear incrementally than as a result of some huge politically-inspired push. The only thing that's likely to provide that sort of push at the moment is an incoming "dinosaur killer", and by the time that we've got twenty permanently-inhabited space stations, that is unlikely to be much of a real threat. Otherwise, it's the old "boiled frog" combination of overpopulation and overconsumption that are going to kill your species.

Hmmm, I can't see how they couldn't have, but I don't actually have a solid datum to hang that assertion on. Have to think on that somewhat more.) Then again, higher temperature stars certainly can have some pretty savage stellar winds too. Odds of a civilisation developing around a Wolf-Rayet star?

  As far as my religious belief, there is no such thing as a gay marriage. A marriage is one man and one woman. As such, any sex between two people of the same gender is adultry because it is outside the confines of marriage. Thus, there is still the same sin, and I don't believe the Church should condone a relationship based on sin.
  That said, I don't think that simply commiting adultry is reason to be kicked out or extricated from the church. Everyone sins, and everyone who asks is forgiven. So the only problem is when the church says "this lifestyle of adultry is acceptable in these circumstances" when it condones gay marriage. It turns the proper perspective of 'I am sinful, but try not to be' on its head, making it 'I am planning to continue sining, and I don't care'.
  Outside of my church and my religion, I have no objection to gay marriages or civil unions, since they don't follow the same purpose or requirements.

  Its why, for example, when we let minors testify in court, we first question them so that we're sure they understand what telling the truth involves, and why they should - "because it's wrong not to."
  Seems to me the only one to blame here is god for releasing a model with incomplete software a la Toyota.
  Well, I believe God knew that it was going to happen. I don't think God truly intended for us to be little naiive automatons, we were meant to have free will to choose to do good or evil, so as to bring honor to him when we do good. That said, I don't think Adam nor Eve knew what they did was wrong or sinful. However, that doesn't change an outside analysis of whether it was, in fact, wrong.
  It comes down to your point of view as to how you feel about this. I assume you consider the Admiral Ackbar "It's a trap!" perspective correct.

  Should the church consider it okay for her to marry a man, since she is legally a woman, even though genetically she is XY? Or is this a "same-sex wedding" in god's eyes?
  Or should she only be allowed to marry a woman, since she is genetically XY? It might "look" like a lesbian relationship, but god knows better (he sees the hidden places and all that)?
  And no, male-to-female transsexuals are not eunuchs - they can have (multiple) orgasms, same as any other woman, so no "they can't marry either one, because they are eunuchs".

  Both heard God's command (do not eat of the tree in the middle of the garden) and the consequences (you will die), yet ate it anyways. Whether or not they knew disobedience was wrong, they still disobeyed. Your examples show ignorance of the cause and effect, while Eve and Adam were not ignorant of God's command.

  I will assume they became a transsexual before they became a believer, as I doubt a (strong) believer would undergo 'gender reassignment'.
  Firstly, what the state says doesn't enter into it. Do they have XY? They are a man, end of story, regardless of what they do with surgery and hormones. As you said, God sees the hidden places and formed us in the womb. I also doubt he very much likes 'gender reassignment' for this reason.
  As for whether it is a sin for them (for example, XY transgender male and XX female) to marry, I don't think so. I think any sin would have been the 'gender reassignment', but if they have been forgiven for that I can't think of any sin they would be committing in marriage (since my reading of 'sodomy' refers to actual gender, not sex organs), although I think a case could be made against sexual attraction to someone who looks like a member of your own gender (which could be a sin for the non-transgender person).
  If they should marry is another matter. I can think of two verses (conveniently adjacent) off the top of my head which would provide guidance. 1 Corinthians 7:36-38, speaking of whether it is wrong to take the virginity of an older woman.
  
  If anyone thinks he is acting improperly toward the virgin he is engaged to, and if she is getting along in years and he feels he ought to marry, he should do as he wants. He is not sinning. They should get married. But the man who has settled the matter in his own mind, who is under no compulsion but has control over his own will, and who has made up his mind not to marry the virgin—this man also does the right thing. So then, he who marries the virgin does right, but he who does not marry her does even better.
  My thought is that wrt transsexuals, they would be better to stay unmarried if both they and their significant other have agreed that it is best. However, if they are unable to control other sexual sins without being married (which we assume is

  You would assume wrong in many cases. While people are born gender-incongruent, the environmental pressures to deny it, to suppress it, and to conform to "norms" are strong. Transsexuals don't see surgery as changing their sex so much as affirming their sex and correcting a mistake.

  ... and we now know that the part of the brain that controls your gender identity is associated with a specific area of your brain, and that a gene in m2f transsexuals doesn't activate fully in the presence of testosterone, leading to less or no functional differentiation in that part of the brain from the default female configuration, and results in gender incongruity - and it starts in the womb in the 1st trimester. Transsexuals are born, not made, and it all has to do with prenatal hormones and the fetus' genetic makeup.
  It literally is the case of "a woman's brain in a man's body."
  You wouldn't like it. But worse, you wouldn't like being forced to conform to something you aren't.

It would be like asking someone to pray to change their skin or eye color.
  Here's something to think of. If you know 100 people, then you probably know at least 5 who either have struggled with, or are currently struggling with their gender, at least some of the time. If you're like most people, you've run into several thousand people over the course of your life, so you've certainly interacted with at least one male-to-female transsexual without even knowing it, and you accepted that they were a woman. You may have even felt a twinge of lust in your heart.
  
  I would not marry a transsexual.
  
  If she didn't tell you, how would you know?
  Seriously ... if she didn't tell you, how WOULD you know? Do you think you can tell just by looking at one? By talking to them? Transsexuals aren't all 6'2" with hands the size of basketballs and size 13 shoes.
  And why should she tell you? Do you feel you need to disclose that you had your appendix taken out at 13, or that you had a broken bone set at 17, or that you had a cavity filled at 15, or laser eye surgery at 25, or a measles vaccination when you were a kid? Should she disclose to you that she was raped and beaten by the last man she was in love with when she told him? Or that her family rejects her because they put their religious dogma over any family ties? Or that they put up with years of being bullied in school?
  This is actually a topic of debate - the whole "when do you tell" question. But what I am asking is, how would you know, and what would you do if, after you were married, you found out that the person you love had had a sex change? "What god has joined, let no man put asunder."

  Well, back on topic, I don't think that doesn't apply to the story in the Garden. Adam was told not to eat the fruit in the middle of the garden, Eve knew that as well, and both knew the consequences.

  Obviously, I am not an expert in gender incongruity or the conditions which cause it. I'm willing to admit that I'm probably totally off-base with some of my assumptions.

On the contrary, are you aware what proportion (if any) of gender uncertainty has no known physical cause?
  All that said, even assuming it is a sin, I wouldn't call it unforgiveable, though I would again need to defer to someone who has actually studied this topic. Personally, I have other topics of more personal importance that I spend my time with, though I'm glad you've piqued my interest.

I believe you are correct. We are finding out more information about our system and the surrounding objects all the time.

We know the moon has effects to cause destruction, I wonder if these unknown gravitation forces in our surrounding system to cause quakes or other changes on our planet.
To go off topic a little bit. I think about why the asteroid belt never formed as a planet. In my opinion I think we should go to the belt more then we do instead of going to some distant brown dwarf star.
