Can you provide a detailed breakdown of fusion and the life cycle of a star?
Understand the Problem
The question is asking for a detailed explanation of nuclear fusion and the life cycle of stars, highlighting key concepts, stages, and important terms related to these topics.
Answer
Stars form in nebulas, mature via nuclear fusion, and end as white dwarfs, neutron stars, or black holes depending on mass.
The life cycle of a star starts in a nebula, where gas and dust condense to form a protostar. Nuclear fusion ignites, and the star enters the main sequence phase where it spends most of its life. Low-mass stars become red giants, shedding outer layers and forming white dwarfs, eventually cooling into black dwarfs. High-mass stars may become supernovae, resulting in neutron stars or black holes.

More Information
Stars undergo nuclear fusion to produce energy and form various elements throughout their life cycles. Their lifecycle depends on their mass, with low-mass stars quietly ending as white dwarfs, while high-mass stars may explode dramatically as supernovae.
Tips
A common mistake is confusing the end stages of high and low-mass stars, as they evolve differently.
