A star's life span is much more than 10 billion years. It would pass through various stages, from nebula to ( ,perhaps, the current stage) supernova or neutron star or Black Hole.

There seems to be a brief window of grace between B instant and star formation. But the phases of transition are Blue star to nebula to blue-white supergiant star to neutron star to supernova to black hole. The Sun, our star, is only 4.6 billion years old (by). It could eventually turn red. giant by roughly the tenth and turn into a black dwarf later. The Sun is not in the middle ages; rather, it is currently in a high- lively forties in people.

undefined In the 13 billion years that you would observe a star cluster, you would see different stages of stellar evolution: the cluster would form from a cloud of gas and dust; stars would be born within the cluster, go through their main sequence phase where they burn hydrogen; eventually, some stars would explode as supernovae, enriching the interstellar medium with heavy elements; the cluster would gradually lose its brightest and most massive stars through stellar winds or supernova explosions; and finally, after billions of years, the cluster would contain mostly low-mass stars, and it might disperse
