What makes stars different from each other?

The video explores the diversity of stars, explaining their formation from the interstellar medium and the development of protostars. It discusses the transition to main sequence stars, highlighting the role of mass, age, and composition in determining star characteristics. The video also covers variable stars and the instability strip, emphasizing the complexity of stellar evolution. Future topics include black holes and neutron stars.
