What is the life of a star cycle?
First there is a large (possibly up to 100 light years across) cloud of gas and space dust. This can also include fragments of old exploded stars (their expelled gas, metals, etc.) As the cloud accumulates more and more material, the cloud will begin to collapse inward due to the force of gravity. This happens when the outward forces can no longer apply enough pressure to counteract the gravitational pull of this mass of gas. As the cloud collapses, it breaks down into smaller parts which continue to collapse inward. The effect of the gas collapsing is gravitational potential energy, released as heat.As temperature and pressure increase, a round sphere of spinning superheated gas forms a proto-star. This is the conception of the star. Millions of these proto-stars can be created from one gas cloud. Eventually, larger proto-stars’ cores will ignite the nuclear fusion process (hydrogen fuses into helium typically) when the temperature reaches a certain level. Hydrostatic equilibrium is s
