Life Cycle of a Star.

   The life cycle of a star can be related to the life cycle of a human, but not exactly. So let's see how they are related. Let's look at the picture.

   In the picture we can see the comparison of human life cycle to the star life cycle. A star’s life is long compared to that of a human, but we can see the stages of stellar birth, aging, and death in the heavens. They follow a pattern similar to many of the life cycles we see here on earth. Stars are born, they “grow up,” exist many years, and then they die, and there’s an exciting battle between the force of gravity and gas pressure to that makes it exciting and potentially explosive!
