    Default Surprising Star Explosion Upsets Theory

    We're studying stars right now. Wonder why they teach us stuff as fact and make us test over it in science when science especially on this kinda stuff is always changing.

    http://news.yahoo.com/s/space/surpri...GKDExq6joDW7oF

    A recently-observed supernova is making some astrophysicists doubt prevailing theories for how stars die.

    The massive star, located in galaxy UGC 4904 about 77 million light-years from Earth in the constellation Lynx, threw off a huge amount of material on October 20, 2004. This star, which may have been what's known as a Luminous Blue Variable (LBV), was mistaken for a supernova, as LBV's often are. In fact, some observers refer to them as "supernova imposters."

    Then, in the fall of 2006, the star exploded into a full supernova, much sooner than expected. Dubbed Supernova 2006jc, the dying star's blast wave apparently reached the shell of drifting material released in the earlier outburst in mere hours.

    The wave heated the ejected gases to millions of degrees, sparking X-ray emissions of an intensity and duration never before detected. NASA's Swift satellite recorded X-rays brightening from the supernova for an unprecedented 100 days. All previously observed supernovae have initially appeared bright in X-rays before quickly turning invisible.

    "We have never observed a stellar outburst and then later seen the star explode," said University of California at Berkeley astronomer Ryan Foley.

    Using the 10-meter (32.8-foot) Keck telescope in Hawaii, his group observed narrow helium spectral lines that showed that the supernova's blast wave ran into a slow-moving shell of material, presumed to be the upper layers of the star ejected two years earlier. Had the supernova's fast-moving blast wave been measured unobstructed, its spectral lines would have been much broader.

    "It disrupts our current model of stellar evolution," Foley said. "We really don't know what caused this star to have such a large eruption so soon before it went supernova."

    Foley's colleague, Nathan Smith, also of the University of California at Berkeley, said, "The fact that we have no well-established theory for what actually causes these outbursts is the elephant in the living room that nobody is talking about."

    The supernova, classified as a variant of a Type Ib, was first sighted by Japanese amateur astronomer Koichi Itagaki, American amateur astronomer Tim Puckett and Italian amateur Roberto Gorelli.

    I don't know what she posted as I have her on ignore but it must have been Bush's fault.
    When I die I'm sure to go to heaven, cause I spent my time in hell.

    You get more with a kind word and a two by four, than you do with just a kind word.

    what an inapropriate response

    What they are really saying is they've looked back in Time. That star, if it's REALLY 77 MILLION light-years away, actually blew up 77 Million years ago, and we're seeing it only now.

If you can eliminate that fear—not through arrogance or just wishing difficulties away, but through hard work and preparation—you will put yourself in an incredibly powerful position to take on the challenges you face" - Pete Carroll.

    I dunno; if you have someone on ignore yet respond to them anyways, I think it's pretty stupid.

    I think it's pretty stupid when people follow you around saying they have you on ignore.

    As for the responce. What, not like he could see it before someone quoted me.

    Gotta agree with that.

    LN, science class will do that to you. My daughter just sat through the Gore guessumentary in class, and hated being forced to do so. She told me she was proud up until that day to say she never saw it. Love her!

    They went from the theory of global warming to the theory of evolution. To her teacher's credit, she intro'ed the evolution unit by telling the kids it is a theory, but it must be studied.

    Actually, gravity affects the speed of light. So, no telling HOW far away it actually is/was, or when it blew up.
    Blessed be Your name, when the sun's shining down on me, when the world's "all as it should be," blessed be Your name!
    Blessed be Your name on the road marked with suffering, though there's pain in the offering, blessed be Your name!
    Every blessing You pour out I'll turn back to praise. When the darkness closes in, Lord, still I will say...
    Blessed be the name of the Lord!
    Blessed be Your name!
