Introduction: Did you ever draw a picture of the Sun when you were young? Chances are you colored a simple yellow circle. However, peel back its layers, and our closest star is much more complex than it first appears. Although it is fairly average compared to other stars, the dynamic structure and nature of the Sun provide us with the heat and light necessary for life to exist on Earth.
