The nebula disperses the elements necessary for future star and planet formation, continuing the cosmic cycle of life. Helium Accumulation and Core Contraction As the hydrogen in the core depletes, the fusion rate slows down because there is less fuel available.

This glowing shell of ionized gas will be illuminated by the hot core left behind, providing a breathtaking, albeit brief, display for any observers in the solar system. Having already endured for 4.
This process generates the outward pressure that perfectly balances the inward pull of gravity, creating the equilibrium that has allowed life to flourish for billions of years. It will shed layers of its outer atmosphere into space, creating a spectacular cloud of gas and dust known as a planetary nebula.

This white dwarf will be roughly the size of Earth but contain most of the sun's original mass, slowly cooling and fading over billions of years. The remaining core, composed primarily of carbon and oxygen, will collapse under gravity but will be prevented from becoming a neutron star or black hole due to its low mass.
