Everything follows the same cycle in all its existences. A cycle of birth, life and death of a being. And even though some things may not be connected, or even four light years apart, like stars and humans. They are still virtually identical. Human beings are born, while stars are created. So, a human being works all his life: at school, at work, at work or at personal work. On the other hand, a star's job is just to be. But through every cycle of life comes death. While humans and stars die for different reasons and ways, humans and stars follow the same pattern, just with different details. All things have a life cycle of creation, life and death, including stars. The birth of a star begins with an interstellar cloud. An interstellar cloud, or interstellar medium, is a cloud composed of hydrogen gas and dust. Furthermore, the interstellar cloud is a filled space between other stars, which has a very low density (interstellar medium). A star forms from an interstellar cloud by combining with other atoms. With the temperature going from zero to zero degrees, the atoms of the gas begin to get sick together. Then the star forms in a molecular cloud. A molecular cloud is just a thick compact of interstellar gas and dust. Then the interstellar collapse under the gravitational force of a supernova. A supernova, as NASA explains, is “A star that suddenly increases significantly in brightness due to a catastrophic explosion that expels much of its mass” (NASA. NASA). The collapse of interstellar clouds then begins and they rotate into a flattened disk-like shape. The disk becomes dense, after mixing in the center, and the temperature begins to rise. As the mixing and spinning continues, more and more material blends together to form a cap... at the center of the paper... the process continues. And with the life cycle of the star it is no different. The death of a star, a supernova, could cause other stars to begin their journey. And the life cycle of stars will continue endlessly.
