Abstract
When soft X-rays were first detected with photon energies ~1/4 KeV, it was unclear whether their origin was galactic or extragalactic. Then the fact that the intensity did not go to zero in the galactic plane where the absorption optical depth is very large demonstrated that they were at least partly galactic. In the last few years, several experiments have attempted to measure the X-ray shadows of the Small Magellanic Cloud, M31, and the Large Magellanic Cloud. All have produced null results. The origin of the bulk of this radiation is convincingly galactic.
