摘要：
Using a simple model for the thermal properties of very old supernova remnants and superbubbles, we have found that the observed background soft X-ray and extreme ultraviolet spectra can be produced by a superbubble formed by the injection of about 1052 erg into the interstellar medium surrounding the Earth roughly 4 x 106 yr ago. © Royal Astronomical Society • Provided by the NASA Astrophysics Data System.
