WebMain sequence turnoff. HR diagrams for two open clusters, M67 and NGC 188, showing the main sequence turn-off at different ages. The turnoff point for a star refers to the point on the Hertzsprung–Russell diagram where it leaves the main sequence after its main fuel is exhausted – the main sequence turnoff . WebOpen Clusters.

WebOpen clusters are loosely bound groups of a few tens to a few hundred stars. They are found in spiral and irregular galaxies. Open clusters are much smaller and more sparsely … Open star clusters are young, loosely bound gatherings of stars. The stars in these clusters were born together. They’re still sometimes moving within the nebula, or cosmic cloud, of their creation. They’re occasionally called galactic clusters.

More than 1,100 open clusters have been discovered within the Milky Way galaxy, and many more are thought to exist. They are loosely bound by mutual gravitational attraction and become disrupted by close encounters with other clusters and clouds of gas as they orbit the Galactic Center.
