STAGES OF EVOLUTION Formation of stars can be generally described in four stages that span the time line within a molecular cloud. Once the star is freed from the dust it will be surrounded by a circumstellar disk of material from which it was made of. Sometime in the future the disk will develop forming planets and beginnings of a solar system.
