Supernova remnants, planetary nebulae and superbubbles: prospects for   new XMM-Newton observations
  Important results achieved over the last years on supernova remnants, planetary nebulae and superbubbles are briefly reviewed in the context of X-ray observations. I intend to review the important open scientific questions in these fields, and the specific contributions that can be made by XMM-Newton.
