In which galactic structures are open star clusters overwhelmingly found?
Answer
Within the disks and spiral arms of spiral galaxies
Open star clusters are characteristically located within the active star-forming regions of spiral galaxies, specifically concentrated in the disks and spiral arms. This location is dictated by the fact that spiral arms possess higher densities of interstellar gas. This abundant gas provides the necessary raw material required for the intense bursts of star formation events that lead to the creation of these young, ephemeral groupings. Conversely, elliptical galaxies are generally older systems that have already consumed most of this star-forming fuel, explaining why open clusters are conspicuously absent from them.
