Scientific American is carrying this summary of a new study conducted on the center of the Milky Way using the Chandra X-ray telescope. Seems there is a "diffuse" source of x-rays in there somewhere, one that can't be accounted for with supernova, big horking black holes, or other exotic stellar critters. The Chandra telescope revealed them to be coming from two plasma formations, one at 10 million degrees C and the other at 100 million degrees C. While interesting, it just pushes the problem one step backward, since astronomers have no idea what could be generating the plasmas.
