Study of the interstellar medium (ISM) is at the root of understanding how the stellar population and the metalicity has been built up in the disk of the Milky Way and similar systems. A closely related question is why is there still an ISM remaining in our Galaxy? This appears to be because star formation in molecular clouds is not very efficient, because of feedback processes from the stars that are born there (outflows, winds, ionization, radiation pressure, supernovae). Because of this feedback, the reservoir of the Galactic ecosystem, the ISM, is neither a single state nor static. Rather it is a both complex and dynamic consumable.

对星际培养基（ISM）的研究是了解恒星种群和金属性如何在银河系和类似系统的磁盘中构建的。 一个密切相关的问题是，为什么我们的银河系中仍然存在ISM？ 这似乎是因为分子云中的恒星形成不是很有效，因为来自那里出生的恒星的反馈过程（流出，风，电离，电离，辐射压力，超新星）。 由于这种反馈，银河生态系统的储层ISM既不是单个状态也不是静态的。相反，它既复杂又动态的消耗量。
