Stars are a fascinating component of our universe. They may seem like permanent objects in the sky, but technology has allowed us to photograph the heavens, and now we know more about stars than ever before. They are born, they live, and then they die. How does this happen?
That’s what this activity is all about! 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!
