Stars much heavier than the Sun are extremely luminous and drive strong stellar winds, blowing a large part of their matter into the galactic environment before they finally explode as  super- or hypernova. By this strong feedback, massive stars regulate the star formation and the further development of the cluster in which they were born. Massive stars generate most of the ultraviolet radiation of galaxies -- the whole Universe was re-ionized by the first (super)massive stars -- and power their infrared luminosities. Massive stars are bright signposts that help to determine the age, scale, shape, and content of the Universe. Quantitative knowledge of the action of massive stars is prerequisite to comprehend the Universe we see.
