Science of Stars Nancy Vasquez SCI 151 September 23‚ 2012 Robert Austin Abstract When discussing the Solar System‚ the planets are what are mostly thought of. Many other objects orbit around the sky such as stars‚ asteroids and meteors. Stars have many properties of which will be discussed throughout this paper. Properties of Stars * Stars are determined by their brightness‚ distance‚ luminosity‚ radius‚ chemical composition and temperature (Strobel‚ 2007). * When determining

Life cycle of Stars Our Sun is a perfect example of a star‚ and there is an incredible amount of stars in the Universe. Stars live for a very long time; millions‚ billions‚ or tens of billions of years so we can never really observe the life of a star; its birth‚ life‚ and death. In determining the life cycle of a star‚ astronomers observe many of the billions of stars around us and see them at different stages of life‚ therefore putting together a star’s evolution. It is a star among hundreds

and gas‚ most of the gas that makes up the nebula is hydrogen. Sometimes nebulas can remain mostly static for billions of years. Eventually though a passing star or shock wave from a supernova will disturb the gas and dust. The dust and gas may then start to clump together‚ gravity will then clump more and more gas together‚ this is when the star starts the next part of its life cycle. Protostar: A protostar is when the gas has clumped together and it getting hot but has not reached what is

If someone were to rely solely on television media‚ it wouldn’t surprise me if he/she thought that America’s schools were being taken over by these so-called "juvenile super predators." The American people would assume that every quiet kid who gets picked on is going to turn around in school one day and start unloading his newly acquired firearms on his peers. This is hardly the case. While there may be an occasional "super-predator‚" the media has highly over publicized these rare‚ extraordinary

The basic idea of star formation is gravitational collapse – the contraction of a region of gas under the influence of gravity. This is a simple process that would be expected to occur in any region of material dense enough for collisions between atoms to radiate away energy. However‚ the gas must be dense enough for collisions to occur and the temperature must be low enough for the atomic velocities not to be able to escape the system’s gravity‚ so star formation only occurs in a few areas. The

Shooting an Elephant Summary: Set during the early 1900’s‚ the narrator recount his experiences as an English police officer stationed in Burma. He often describes that the British presence there were greatly despised and that he himself has been a target multiple times by the Burmese people. “As a police officer I was an obvious target and was baited whenever it seemed safe to do so.” (229) Being there to do the dirty work of the British empire‚ the narrator gets to see what imperialism really

In George Orwell’s essay “Shooting an Elephant” (1936)‚ he reveals that he despises the very idea of imperialism. Orwell shows this by using an extended metaphor throughout the entire essay. The metaphor is shown through the story of him shooting an elephant. He is representing the entire British nation‚ and their imperialistic values. He shows that he does not really want to shoot this elephant if it is not necessary but the Burmese people keep pressuring him to do something and to do it right
