摘要：
The Chandra X-ray Observatory is providing remarkable new views of massive star-forming regions. Very young complexes are suffused by parsec-scale diffuse X-ray structures outlined by heated dust seen in mid-infrared images; these are the long-sought signatures of multi-million-degree plasmas created by fast O-star winds. In older regions we see much brighter diffuse emission regions; these are likely the X-ray remains of massive stars that stayed close to their birthplaces, exploding as cavity supernovae within the superbubbles that these clusters created.
