Question:
Explain how observations of star clusters are used to test theories of stellar evolution.
Evolution of Stars:
The birth of a star occurs to the gravitational effects on nebulae. The dust and gas in a nebula begin to clump together in spots of larger gravitational pull. As more and more gas and dust gather, protostars are formed, and as these protostars reach a high enough temperature, fusion starts within them. At this point, the star is in what is called the main sequence of its like and it remains in this main sequence for a long time. After that, it eventually becomes a red giant and goes supernova to mark its end.
