Explain the steps of the life cycle of a star. Beginning with a nebula and ending with old age/death of a star, explain each step in a star’s life cycle.
_______________________________
In a stars lifecycle, it begins with a nebula. A nebula is an area of dust and gas in space. Over time, the dust and gas accumulates in a spinning cloud. This compacts more to form a protostar. When the gases in a protostar become more compact, the heat and pressure gets to a point where the gas will catch fire and a star is born. After a star has burned for some time, it will change to be a red giant or red supergiant. Medium-sized stars will become red giants, and large stars will become red supergiants. At the end of a star's life, it will turn into a dwarf or a black hole. The giants will form into dwarfs, and the supergiants will turn into blackholes
