Everything has followed the same cycle since its existence. A cycle of birth, life and death of a being. And even though some things may not be connected, or even four light years away, like stars and humans. They are still very identical. Humans are born while stars are created. Then, humans work throughout their lives: at school, to go to work, or for personal work. On the other hand, a star's job is simply to be. But with every cycle of life comes death. While humans and stars die for different reasons and ways, humans and stars follow the same pattern, but with different details. All things have a life cycle of creation, life and death, including the 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. In addition, the interstellar cloud is a filled space between other stars, which has a low density (interstellar medium). A star forms from an interstellar cloud by combining with other atoms. With the temperature just above zero degrees, the atoms in the gas begin to contract together. The star then forms in a molecular cloud. A molecular cloud is just a thick compact of interstellar gas and dust. Then the interstellar collapses under the gravitational force of a supernova. A supernova, as NASA explains, is “a star whose brightness suddenly increases significantly due to a catastrophic explosion that ejects most of its mass” (NASA. NASA). Interstellar cloud collapse then begins and transforms 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 materials mix together to form a protected medium of the paper......ys continues. And the life cycle of the star is no different. The death of a star, a supernova, could prompt other stars to begin their journey. And the endless life cycle of stars will continue. Works Cited “Disk Formation”. Disc training. Np, and Web.
