我们简要回顾了大质量恒星的反馈效应，通过他们的恒星风和超新星爆炸，在恒星形成的地区，他们出生。我们举几个例子，跨越了很大的空间尺度，从100 pc到100 kpc：所谓的“本地泡沫”。（实际上是一个在银盘两侧延伸的开放的双极结构）;猎户座大星云及其充满热的MK流出等离子体的开放腔;船底座大星云及其扩展的弥漫X射线发射;大麦哲伦星系中的30多尔区域及其各种气泡;以及原型星暴星系M 82的扩展双极外流，受到附近星系群的影响。最后，我们强调这些现象在所有空间尺度，银河系和河外的相似性。
We briefly review the feedback effects of massive stars, via their stellar winds and supernova explosions, on the star-forming regions in which they were born. We give a few examples, spanning a wide range of spatial scales, from ∼100 pc out to ∼10 kpc: the so-called “Local Bubble” (in reality an open bipolar structure extending on both sides of the galactic disk); the Extended Orion Nebula and its open cavity filled with a hot, MK outflowing plasma; the Great Carina Nebula and its extended diffuse X-ray emission; the 30 Dor region in the LMC and its various bubbles; and the extended, bipolar outflow of the prototype starburst galaxy M 82, influenced by a nearby group of galaxies. We conclude by stressing the similarity of these phenomena across all spatial scales, galactic and extragalactic.
