Massive stars represent the hottest and most luminous stellar component of the Universe, and are the crucibles in which the lion's share of the chemical elements are forged. Throughout their lives, matter, energy and momentum are injected into the surrounding interstellar medium by their powerful radiation fields and stellar winds, and by the dramatic supernova explosions that mark their deaths. These rapidly-evolving stars drive the chemistry, structure and evolution of galaxies, dominating the ecology of the Universe with far-reaching consequences.

大质量恒星代表了宇宙中最热、最亮的恒星成分，是锻造大部分化学元素的坩埚。在它们的一生中，物质、能量和动量通过它们强大的辐射场和恒星风以及标志着它们死亡的戏剧性超新星爆炸注入周围的星际介质。这些快速演化的恒星驱动着星系的化学、结构和演化，主导着宇宙的生态，并产生深远的影响。
