Science of Stars Paper SCI/151 December 14, 2011 Science of Stars Paper Stars are the most recognized astronomical objects all over the universe. They represent the most fundamental building blocks of the galaxies. The histories of the stars in the galaxies are traced through the distribution, compensation and the age and dynamics and evolution of that galaxy. However, the stars are responsible for the manufacture and distribution of heavy elements such as carbon, nitrogen, and oxygen, and their characteristics are intimately tied to the characteristics of the planetary systems that may coalesce about them. Consequently, the study of the birth, life, and death of stars is central to the field of astronomy. ] (Netting, 2011) We explore the complexity of the stars and what astronomers use to determine fundamentals of their temprature, speed , rotation, and composition.…show more content…
The tremendous distances to the stars give us some perspective on the technological challenge of astronomy. For example, because the largest star of the Alpha Centauri system is roughly the same size and brightness as our Sun, viewing it in the night sky is somewhat like being in Washington, D.C., and seeing a very bright grapefruit in San Francisco (neglecting the problems introduced by the curvature of Earth). It may seem remarkable that we can see this star at all, but the blackness of the night sky allows the naked eye to see it as a faint dot of light (Cosmic perspective 2010). Back in the 20th century people would classify the stars based on the brightness of it. The stellar paralaxthe in the star caused by earth’s rotation is the most direct way to determine the stars
