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. WebFeb 23, 2024 · This cluster was formed after the collision of two large clusters of galaxies, one of the most energetic events known in the universe since the big bang. Because the major components of the cluster pair — stars, gas and the apparent dark matter — behave differently during collision, scientists were able to study them separately.

WebNov 24, 2024 · How do star clusters confirm that stars evolve? Cluster color-magnitude diagrams change with age. More massive stars evolve quicker than low-mass stars. The hot, luminous main sequence stars will die before the cool, dim main sequence stars. ... Since all the stars in a cluster formed at the same time, they are all the same age. ...
