How do stars in a cluster change with time
WebStellar Evolution Black Holes All stars form in nebulae, which are huge clouds of gas and dust. Though they shine for many thousands, and even millions of years, stars do not last forever. The changes that occur in a star over time and the final stage of its life depend on a star's size . Life Cycle of a Star Credit: NASA WebJun 14, 2012 · Star clusters are self-gravitating groups of stars. They are spherical because there are not enough interactions to average out the angular momentums of the individual stars, which is what you need to do to form a disk. The distance between stars is large compared to the size of the stars.
