Life cycle of a star
<p>Stars are large spheres of gas atoms and molecules that produce energy through their nuclear activities, and as a result of this energy that causes light, they shine. Stars convert the hydrogen in their cores into helium. The energy created by this change and transformation is released into space. The temperature inside and the surface of these are different so that it is thousands of degrees on the surface and much more inside. At these temperatures, the building material cannot exist in solid or liquid form, so this state of matter is called plasma. The gasses that form stars are much denser than the gasses that normally exist on Earth’s surface. The life of stars begins when a large cloud of gas and dust exists in the interstellar space. The cloud of gas that is called a Nebula is the place where stars are born. The type of material in the clouds is different and it is divided into two structures: dusty and gaseous. </p>
