Gamma rays origin

    some news about the origin of gamma ray bursts, this may be
    old news to some.there have been many theories for the production
    of gamma rays, it seems now that the search is narrowing.


    Using NASA's Chandra X-ray Observatory, scientists have confirmed that a gamma-ray burst was connected to the death of a massive star. This result is an important step in understanding the origin of gamma-ray bursts, the most violent events in the present-day universe. The Marshall Center manages the Chandra program.


    Astronomers from the University of Michigan and the Department of Energy's Los Alamos and Livermore national laboratories described these new details -- including their measurements of the brightest optical celestial object ever recorded -- in the April 1 issue of the science journal Nature.

    I agree that "Hypernovae" and their direct connection to large GRB's can't be overlooked, or discounted when talking about large GRB's. Too much evidence of the unrefutable kind. Also, haven't seen much about them posted on PF, except yours above.

    Anyone; Look up these:

    thanks LABGUY
    its nice to talk about things that have a solid foundation rather
    than hypothetical theories.

    this clip from SCI SCOOP, posted by LABGUY above.

    about 100 times more intense than anything we've ever seen before. It's also much closer to us than all other observed bursts so we can study it in considerably more detail," said Akerlof. ROTSE teammember Michael Ashley noted, "During the first minute after the explosion it emitted energy at a rate more than a million times the combined output of all the stars in the Milky Way. If you concentrated all the energy that the sun will put out over its entire 9 billion-year life into a tenth of a second, then you would have some idea of the brightness.

    I like this particular part of your post. Amen.

    Those numbers given on the sites are HUGE amounts of energy.
