These results were presented May 29, at the American Astronomical Society Meeting in Honolulu, Hawaii.<br /><br />The chromosphere is important because it is largely responsible for the deep ultraviolet radiation that bathes the Earth, producing our atmosphere's ozone layer, and it has the strongest solar connection to climate variability. The new result also helps explain a mystery that's existed since the middle of the last century -- why the chromosphere (and the tenuous corona above) is much hotter than the visible surface of the star. "It's like getting warmer as you move away from the fire instead of cooler, certainly not what you expect," said Scott McIntosh, a researcher at Southwest Research Institute, Boulder, Colo.<br /><br />“This work finds the missing piece of the puzzle that has fascinated many generations of solar astronomers. When you fit this piece in place, our vision of the chromosphere becomes clear,†said Alexei Pevtsov, Program Scientist NASA Headquarters, Washington.<br /> /><p><hr /></p></p></blockquote> <div class="Discussion_UserSignature"> </div>

I think I'm going to need to see a soundwave heat plasma to 10's of millions of degrees and keep it there for hours at a time before I'm going to believe this idea. <br /><br />Electrical currents seem to be the one and only thing that astronomers will not consider as a heat source of the corona. <div class="Discussion_UserSignature"> It seems to be a natural consequence of our points of view to assume that the whole of space is filled with electrons and flying electric ions of all kinds. - Kristian Birkeland </div>
