Orion Nebula - 1060 Words

The Orion Nebula contains one of the brightest star clusters in the night sky. With a magnitude of 4, this nebula is easily visible from the Northern Hemisphere during the winter months. It is surprising, therefore, that this region was not documented until 1610 by a French lawyer named Nicholas-Claude Fabri de Peiresc. On March 4, 1769, Charles Messier inducted the Orion Nebula, M42, into his list of stellar objects. Then, in 1771, Messier released his list of objects for its first publication in Memoires de lAcademie.1 The Orion Nebula is one of the closest stellar regions to the Earth. Using parallax measurements, it has been estimated that this nebula is only 1,500 light years away. In addition, the Orion Nebula is a†¦show more content†¦On April 9, 1998, Cornell University astrophysicist Martin Harwit published his discovery of the presence of massive amounts of water in the Orion Nebula. This was the first time that water has been found in a star-forming region. The find demonstrates that water plays a vital role in star formation. In addition, this discovery implies that water is prevalent in space. Harwit speculates that the water acts as a coolant, by carrying heat away from the condensing clouds. It is believed that this process is necessary to slow down the particles in order to allow the compression of the particles into new stars. 6 The discovery of water in the Orion Nebula will undoubtedly provide the basis for further study. More specifically, it will prompt scientists to search for water in other regions of space at different stages of star formation. Then, if water is present in each, it may suggest that the oceans of Earth are older than even the planet that now contains them. 7 Page 3 Several unresolved problems remain concerning the Orion Nebula. The fate of the protoplanetary disks, for example, is presently impossible to predict. Without a more detailed understanding of how planets actually form, it cannot be assum ed that the events within the Orion Nebula are analogous to the events that led to the formation of the planets in the solar system. Furthermore, the detection of water in the nebula has revealed the need to revise the theory of star formation toShow MoreRelatedInvestigating the History of the Universe and the Big Bang Theory674 Words   |  3 Pagescollapse along this direction.

Nebulae are the birthplaces of stars. There are different types of nebula.

Analysis Of Dulce Et Decorum Est By Wilfred Owen, And...

Man’s Inhumanity to man Introduction DULCE ET DECORUM EST by Wilfred Owen, and This Blinding Absence of Light by Tahar Ben Jelloun, are both powerful texts that give the reader sympathy and strong emotional experiences. When comparing the two texts, there are multiple aspects that they share, for example they both convey a strong message on survival and what it’s like to be faced with death, however the setting, symbolism and themes like hope, and the power of thought are very different. The novel This Blinding Absence of Light is set in the Tazmamart prison in Morocco, where Salim, a prisoner of war, was held captive with 18 other men for 20 years. When confined in a small, pitch black chamber, with only starchy food, sludgy water and what hope they have left, Salim and the men are pushed to their limits of survival under such harsh conditions. Throughout the novel Salim goes on both a mental and physical journey to come at peace with himself, which shapes his perspective of what life means. The text DULC E ET DECORUM EST is set in World War 1 when a group of British soldiers are attacked with chlorine gas. In the rush upon the shells of gas exploding, one soldier does not get his mask on in time. Wilfred Owen portrays in detail the gruesome effects of the gas upon this man and concludes that one may not have the same opinion after being exposed to the first-hand reality of war.

Workplace Ethical Dilema Free Essays

Ethical dilemmas can occur at any workplace. For this reason, codes of ethics are developed to help guide and set the standards for moral conduct for that profession. Code of ethics also helps establish procedures on how to deal with misconduct. We will write a custom essay sample on Workplace Ethical Dilema or any similar topic only for you Order Now While serving in the United States Navy, I came across several ethical dilemmas in my workplace. One dilemma that I remember clearly is one in which an officer (higher rank) and enlisted (lower rank) were involved in fraternization. Fraternization in the Navy is not acceptable and is referred to as a relationship between an enlisted and officer who are dating, who engage in intimate behavior, share a home, borrow money or gamble. Fraternization in the military can be punishable under the Uniform Code of Military Justice. On board the Navy ship there were approximately a total of 350 service members who were both men and women. Interaction between both sexes was inevitable; however two service members on board took it too far. There was a service member (enlisted male) who began to have a relationship with his boss (female officer). Both agreed to keep their relationship a secret while onboard the ship. One after noon I was out in town at a local store when I spotted both members holding hands together. I was not friends with either one, and did not say anything to them. I realized that their behavior was non ethical, but I did not want to be involved. Looking back at the situation my thoughts about it followed the principles of nonmaleficence. Nonmaleficence refers as doing no harm or mischief. I thought to myself that they were not causing harm to anyone therefore I did not want to report them. Through an ethical relativism view I realized that the dilemma was not morally wrong however, the situation in which they were engages did not follow the ethical standards of the workplace. However my view about the whole situation changed when I talked about it with another co-worker and she informed me that the female officer was married. The fact that she was married completely changed my perspective about the situation. Now, not only was it ethically wrong but it was morally wrong too. At this point the dilemma then interfered with my personal values. My personal values are may not be the same to the ones of others; however the choices they made went against my beliefs and values. Growing up I was always taught that fidelity and commitment to your partner is very important. I put myself in the spouse’s shoes and realized I would never want to go through that. The behaviors the engaged were bothersome and I felt very uncomfortable around them. I can relate this dilemma to the thoughts of Socrates, that no one voluntarily does evil when they know good. If evil is done is because there is some type of benefit within for that person committing evil. The officer in this case is aware of the evil she is committing, however she is gaining comfort, perhaps love, or pleasure from her behavior with the enlisted male. Both personnel practiced ethical egoism, due to fact that they only care about their happiness and did not care about those who got hurt. This is when I realized that I needed to speak up about this dilemma. In order to resolve this dilemma I needed to speak up and report what I knew and saw to my higher chain of command. I would have to say that I applied the theory of Kant. Good will and motivation was the base of my decision to report the dilemma. I knew that making this decision was going to bring bad consequences for both members, however I did what I thought was best. In my decision making process with the Kantian approach, ethical decisions were based on my sense of duty. The word duty is derived from the Greek word deon (deontological). Duty refers to the acts of a person based on the principles of morality. In this decision making approach I had to make decisions based on what is right rather than the good or bad consequences that will follow. A person must make the morally right decision regardless of the good or bad outcome. Categorical imperative is what determines whether an act is morally right or wrong. The requirements of categorical imperatives are that moral principles are applied by respecting humanity. In this deontological point of view a person should act rational person and make self-imposed decisions. After reporting the situation to the chain of command, I was asked to speak up and testify along with others who had observed the same behaviors. Both services members were punished by the UCMJ and forced out of the military. The consequences to their behavior are what constitute it to be wrong. The ethical dilemma went against my personal values and belief. This is why I decided to speak up and report what I knew regardless of the consequences. Both members were aware of the good and evil and instead decided to go for the evil not that they could hurt others. This ethical dilemma not only affected them in a personal level but affected the work place as well. After all the consequences, sailors onboard are very careful about fraternization. Workplace ethical dilemmas can happen at any work place, therefore it is important to maintain an updated code of ethics. This will help and guide employees on procedures , employee conduct and misconduct consequences. How to cite Workplace Ethical Dilema, Essay examples

Lincon vs Kennedy Essay Example For Students

Lincon vs Kennedy Essay Many people share similar aspects throughout their lives, but could two significantly relevant people shared such common lives that might even seem eerie. Abraham Lincon and John F. Kennedy were both assassinated. However, apparently there is more to connect them than that. A little part of US history makes you wonder if it is mere coincidence, or maybe planned? Where it all began, Abraham Lincoln was elected to Congress in 1846. John F. Kennedy was elected to Congress in 1946. Whereas Abraham Lincoln was elected President in 1860; John F. Kennedy was elected President in 1960. The names Lincoln and Kennedy each contain seven letters. Both were particularly concerned with civil rights. During their political lives in Washington, D.C., Lincon and Kennedy and their wives lost their children while living in the White House.Seemingly, both Presidents were shot on a Friday, in the head. A very unbelievable fact was that Lincolns secretary was named Kennedy, and Kennedys secretary was named Lincoln!Both were assassinated by Southerners, and were succeeded by Southerners with leaders named Johnson. Andrew Johnson, who succeeded Lincoln, was born in 1808. Lyndon Johnson, who succeeded Kennedy, was born in 1908. Another very significant aspect between Lincon and Kennedy was their assassination. John Wilkes Booth was born in 1839. Lee Harvey Oswald was born in 1939. Both assassins were known by their three names. Both names are comprised of fifteen letters. (Booth ran from the theater and was caught in a warehouse. Oswald ran from a warehouse and was caught in a theater.) However, Booth and Oswald were assassinated before their trials. The life of Abraham Lincon was different from that of John F. Kennedy, or was it? Although two significantly distinct figures in American History lived during two completely different centuries, eventually many facts were brought about that almost were exact. Bibliography:
