Milky Way X-ray mystery solved Astronomers have found evidence that the diffuse haze of X-rays that envelopes the Milky Way is produced by hundreds of millions of individual stars. Until now, the "galactic X-ray background" was thought to be caused by clouds of hot gas in the galaxy. The discovery, made by Mikhail Revnivtsev of the Max Planck Institute for Astrophysics in Germany and colleagues, means that the Milky Way could contain many more stars than previously thought (Astronomy and Astrophysics to be published).
