WebMassive Stars When a star is more than ten times as massive as the sun, it becomes a Supergiant star. Supergiants have the shortest lifespans of any star, as the temperatures in a supergiant's core get so high that it is able to fuse the helium that is left over after hydrogen burning has stopped. WebGlobular Clusters. Globular clusters were given this name because they are nearly symmetrical round systems of, typically, hundreds of thousands of stars. The most massive globular cluster in our own Galaxy is Omega Centauri, which is about 16,000 light-years away and contains several million stars (Figure 22.6).Note that the brightest stars in this … WebDuring this stage, the star is burning hydrogen to helium in its core, and so it is sitting on the Main Sequence. Depending on its mass, it may live only 1-100 million years in this stage--much shorter than the Sun's lifetime. Once the high mass star starts to run out of hydrogen in the core, and starts burning hydrogen in the shell, it expands ... therapeutics choices
