Star Clusters: Arches and Quintuplet

Caption

Intense wind and radiation forces of massive stars in the Quintuplet excavated the dense gas clouds surrounding the cluster, as indicated by the arrows. The dust discs around smaller stars living in these clusters are exposed to the same harsh environment and should not survive for long periods of time.
