What are the main stages of a star's life cycle, from birth to death?<end_of_turn>
<start_of_turn>model
A star is born from a stellar nebula, then goes through stages of nuclear fusion in its core to produce energy. The lifespan of a star depends on its mass. More massive stars eventually explode as supernovas, while less massive stars become white dwarfs, neutron stars, or black holes.<end_of_turn><eos>
