The video explains the lifecycle of a star as it consumes hydrogen through nuclear fusion and transitions to burning heavier elements. This process leads to the core collapsing and heating up, causing the outer layers to expand and cool, giving the star a reddish-orange color. Eventually, the sun will also become a red giant, potentially expanding enough to engulf the Earth.
