Evolution of Stars

The thought of the evolution of stars seems to be an unspoken idea that many did not know about. The way a star changes over time is due to a revolving energy flow. Our recent objective that was  discussed in class was, “I can describe how stars evolve and die.” The article that I found that is related to our objective is titled Stellar Evolution – The Birth, Life, and Death of a Star. The article begins my initially explaining the Milky Way Galaxy and what it contains. Several hundred billion stars belong inside the Milky Way despite the difference in ages, sizes and masses. It is perfectly normal for an average, bigger star, such as the Sun,to give off small amounts of X-rays and even larger amounts of X-ray during solar flares. Essentially, stellar evolution is the way the stars change and develop over time. Depending on the star’s mass, the evolutions differs from star to star. According to this article, if the star is about the same size as the Sun, it will turn into a white dwarf star. In addition, if the star is even greater in mass, there may be a possibility a supernova explosion may occur which can leave behind a neutron star. If it is an extremely massive star, a black hole can be the result. As a summary to this article, the author explains how to stars begin, evolve, and ultimately die. Initially, stars are formed into giant clouds of dust and gas. They then progress and live their lives as balls of gas that are powered by energy reactions. Eventually, as mentioned above, the size of their mass determines what they evolve into.


During our class lecture, we discussed this objective thoroughly and I personally learned an immense amount of information. I never really knew that the stars transition to different stages in their lives, and it all depends on their actual mass. Also, as a class we completed a lecture tutorial that is titled “Stellar Evolution” which covered the point that a massive star with ultimately turn into a supernova explosion or a black hole. From what we learned through our lecture and Powerpoint slides, since the star was more than 8.0 Suns it would have transitioned into a black hole. The basic idea of this objective was that the determined mass would decipher what the stars turns into. By reviewing this article and completing activities in our lecture tutorial handbooks, I can confidently describe how stars evolve and die.
