What is the correct order of a life cycle of a star?

Answer 1

At the beggining, a star starts out as a nebula. This nebula's gas condenses to form the sun. This sun is called a protostar. When all of the hydrogen is used up in nuclear fusion to produce helium, the star begins to grow and gets to a stage known as the red giant stage. At this point, depending on the size of the star at this point, it can form differently. It can either become a super giant or a dwarf star. When the red giant become a dwarf star, it had collapsed in onitself after burning all possible fuel. It will continue to glow until it reaches its final phase as a black dwarf, which doesn't produce any light and is in a dormant phase. If the red giant becomes a super giant, then it will continue to grow until it burns off all of its fuel and collapses in on itself, where it then explodes into a supernova. If this supernova condenses to quickly, it will form a black hole.
