Telescopes are tools that provide a way to collect and process electromagnetic radiation that is in space and in the universe. Planets, stars, and other galaxies are all visible through telescopes which magnify the image that is out in space so that it is more visible through the magnification. Through the magnification of telescopes astronomers can study and learn more about the planets and stars that are being viewed. Astronomers’ having the ability to have better vision through the magnification of the telescope helps to determine the temperature, speed, and rotation in realms that are an extreme distance away. With magnification of planets and stars that was provided through telescopes astronomers where able to learn a great deal about the stars and their properties that each star possesses. The distance that the star is from earth can help to determine the brightness of the star. Stars appear brighter the closer that they are from the planet earth. Stars also appear brighter depending on the amount of energy that they are generating. Distance from earth and the amount of energy that the star is generating determine how bright a star appears to us on earth. Another aspect of a star that is taken into account when studying the stars is the size of the star itself. If the star is a very large object then it will appear brighter from earth then a star that is much smaller. Temperature is another aspect of stars that is studied; the hotter the temperature of the star is the brighter the star appears on earth. Stars also have life cycles which have been observed and studied. The live of a star or the sun starts in a cold cloud of dust and gas in outer space. When another star explodes it creates waves in the gas and particles and clumps them together, while the…...

The Science of Stars

...The Science of Stars Rochell Clark August 13, 2012 SCI 151 Robert Austin Stars are the majority and most widely acknowledged astronomical components that symbolize the most essential development of blocks of galaxies. The age, disbursement, and framework of the night sky in a galaxy maintain a record of the heritage, characteristics, and evolvement of the galaxy. More important, stars are integral to the fabrication and allocation of heavy elements. Notably corresponding to carbon, nitrogen, and oxygen, their functionality is intimately associated with the capabilities of the planetary models, which in turn associate about them. Subsequently, the analysis of the conception, longevity, and perishing of stars is dominant to the subject of astronomy. Astronomers depend on electromagnetic emissions observed by unique variations of telescopes to calculate the position, structure, conditions, activity, and magnetism of celestial objects. The conduct of the majority of stars indicates they generate a certain measure of energy at each wavelength however additionally carry a pinnacle wavelength and range in which they discharge a significant amount of their remaining stamina. Electromagnetic radiation is transmitted by means of waves at the speed of light (299 792 km/sec) through space. Electromagnetic waves consist of marginal frequency radio waves with the aid of infrared energy and observable luminosity to ultraviolet radiation x-rays as well as high frequency gamma......

...By first glance at the title Stars, I assumed the story would have something to do with the author’s perception of the constellations during the night. By my growing knowledge of the Holocaust I then remembered the Star of David was very significant in determining Jews from non-Jews. It still baffles me to believe that this symbol, which is worn on chains by people of the Jewish faith today, could be used to discriminate one race from the other and aid in their humiliation and ultimately their death. During the reading, I was hearing the similar story of the suffering and measures taken by Jews while in the concentration camps. However, I discovered a different tone than most other stories. Even though Michael was frightened like the rest, he chose to act in order to save his cousin. His courage and quick thinking skills, which benefited Jews greatly during this period of persecution, not only saved himself but saved another by risking his life in exchange. A memory bubble came to me of the numerous times I stood standing in line at a bar without being of the legal age to drink alcohol. Most occasions I would hand the bouncer my authentic I.D. stating that I was underage and he would mark my hand with an “X” or something similar to show that I wasn’t allowed to drink while in the bar. Thinking on my feet, I learned that sometimes the “X” would come right off if I ran quickly to the bathroom to wash it off. Other times I would put Chap-Stick on the back of my......

Star Report

...Majoris is a main-sequence star that can be found in the constellation Ursa Major. It is the third brightest star in the asterism the Big Dipper and the 35th brightest star in the sky. This star has a surface temperature of approximately 20,000 degrees Kelvin and a mass that is six times that of the Sun’s mass. This star is approximately 100 light years away from Earth. Introduction Eta Ursae Majoris is a star found in the constellation Ursa Major. This star has two traditional names: Alkaid and Benetnash. All of the different names for this star have been derived by the Arabic phrase Al Ka'id Banat al Na'ash, which literally means "the Governor of the Daughters of the Bier", or, "The Chief of the Mourners." The mourners in Arabic poetry seem to have been the three stars of the handle of the Big Dipper: Alkaid, Mizar and Alioth. Alkaid is the most eastern star in the Big Dipper; it is the last star of the handle, and is the 35th brightest star in the sky. The constellation Ursa Major is not a commonly known shape in the sky, however it is the asterism known as the Big Dipper. The Big Dipper is composed of seven stars, and as mentioned before Alkaid is one of them. This asterism has a very long history, in many cultures it is seen as a chariot or wagon. These seven stars are not all moving in the same direction, and in time, the Big Dipper will break up. It is only in the past 50,000 years that the “dipper” has actually formed. Alkaid, unlike most of the stars in Ursa Major,......

...In Heather MacDonald’s article “Distorting the Truth About Crime and Race: The New York Times Is at It Again” she alludes that the New York Times is not keeping the public informed of crime rates. Instead, the Times is more interested with “giving specific racial breakdowns of every aspect of police behavior”(MacDonald). She feels that the New York City Police Department is unable to do their job without having to face allegations of racial disparity. Ms. MacDonald indicates that the reason crime rates are higher amongst minorities than whites is not because of racial prejudices. She says it’s because the vast majority of crimes occur in minority neighborhoods by minority criminals against minority victims. Therefore, this drives police officers to those areas to arrest the individuals committing crimes. In 1994, under the New York Police Department Commissioner William Bratton and Mayor Rudolph Giuliani, the proactive policing revolution began. The idea was to remain visible in so called hot spot areas to help prevent crime from occurring. This gave police officers the authority to question anyone that appeared suspicious. According to MacDonald, due to the implementation of this policy “over 10,000 black and Hispanic males are alive today who would have been dead,” but this type of information does not make front page news. It appears that information concerning the positives associated with proactive policing is another issue Ms. MacDonald feels is not being......

...in about 150 BC He ranked the stars he could see in terms of their brightness, with 1 representing the brightest down to 6 representing the faintest. Modern astronomy has extended this system to stars brighter than Hipparchus' 1st magnitude stars and ones much, much fainter than 6. As it turns out, the eye senses brightness logarithmically, so each increase in 5 magnitudes corresponds to a decrease in brightness by a factor 100. The absolute magnitude is the magnitude the stars would have if viewed from a distance of 10 parsecs or some 32.6 light years. Obviously, Deneb is intrinsically very bright to make this list from its greater distance. Rigel, of nearly the same absolute magnitude, but closer, stands even higher in the list. Note that most of these distances are really nearby, on a cosmic scale, and that they are generally uncertain by at least 20%. All stars are variable to some extent; those which are visibly variable are marked with a "v". What are apparent and absolute magnitudes? Apparent is how bright the appear to us in the sky. The scale is somewhat arbitrary, as explained above, but a magnitude difference of 5 has been set to exactly a factor of 100 in intensity. Absolute magnitudes are how bright a star would appear from some standard distance, arbitrarily set as 10 parsecs or about 32.6 light years. Stars can be as bright as absolute magnitude -8 and as faint as absolute magnitude +16 or fainter. There are thus (a very few) stars more than 100 times brighter......

...STARS ESSAY Finding out what job you want to spend the rest of your life doing is a very important part of everyone’s education experience. You get asked the question when you are a freshman in high school, all the way up to when you are out of college. For a lot of people the answer to that question is hard and tough. We understand our strengths and weaknesses but lack the knowledge about all the options we really have. When you’re young all you care about is what job makes the most money. It is a very good idea to have a good income but you need to do something that you enjoy and that will make you happy. You can narrow down what you want to do by just thinking about different things such as your work environment and your option of working in teams or doing your job all by yourself. In this essay I will discuss my personal plans for what career path I am choosing and what information I have found to help me get there. My current educational status is General Studies at Faulkner State Community College. I chose to do this so that I can get my basic classes out of the way and find out what particular classes interest me. Also, attending a two year college will help me get more one on one time than a big university and I think that I will be able to focus more. I want a career that I can go anywhere with and be successful. I would like to do something where I can work indoors and something that has some science based material in it. My plan is to transfer either to South......

...Famous Stars in our Galaxy There are about 300 billion different stars in our galaxy. All of which contain different history, characteristics and general information. They each contain their own story of how they came about. Many of these stars are a part of a certain constellation and have been around for billions of years. Polaris is one the best known stars. (“How Do Stars Form,” n.d.) This star is known by many names like the North or Pole Star. Polaris has not always been the North Star and will not always remain the North Star. As centuries change the North Star will also do so. “A famous star called Thuban, in the constellation Draco the Dragon, was the North Star when the Egyptians built the pyramids.” (earthsky) Polaris will remain as the North Star for many more centuries to come. There was a time where people depended on their lives on this star to guide them. Fortunately, they used the North Star and the Big Dipper without getting lost. “. When slavery existed in the United States, slaves counted on the Big Dipper (which they called the Drinking Gourd) to show them the North Star, lighting their way to the free states and Canada.” (earthsky) Polaris is not hard to miss in the sky; it is the 50th brightest star and does not disappear. The reason this star will not disappear is due to the fact that the Earth’s axis is aligned pointing towards Polaris in the same direction North faces but will eventually shift over time. In comparison to the sun, this star is......

...did not make much of an impact on his life. On the other hand, my father has completely changed my life. He has shaped the characteristics of his only child without even realizing it. My dad has taught me that just because he reflects a negative influence upon my life does not mean that I cannot succeed. I have turned his negative choices into lifelong advice. These experiences made me realize that I do not need to walk in his path of destruction or follow in his footsteps—I can create my own. Watching my father drink his life away has truly inspired me to never give up on my dreams and to never lose hope. As the famous American poet Ralph Waldo Emerson once said, "When it is dark enough, you can see the stars." Living with my father, I am able to see my stars shine brighter each and everyday. Even though my father has not always been dependable, his actions continue to have an everlasting impact on my life. I now know that I can overcome all of life's obstacles thanks to my father who was put on this earth to make me the best, strongest, and most successful person I can possibly be....

...amount of resources to survive. If a species were to continue breeding faster than the food these species eat can reproduce. They would become more competitive against each other. There for, slowing the reproduction of the same species with the weaker genes and the stronger ones would become more abundant. One way of looking at is through the observation of moths. In places where pollution is higher moths with who were more vibrant would find it harder to blend in with the tarnished surroundings, making them more easily targeted as food. Whereas, the darker colored moths would be harder to see by their prey. Eventually the darker moths would out number the vibrant ones. This does not mean the vibrant moths would no longer exist (All About Science, 2010). They would again thrive once the environment became more suitable for them. Which brings us to the evolution on Earth. In the early stages of Earth life was unable to flourish because of the violent space around it and the lack of a stable atmosphere. It is believed the first forms of life were RNA molecules. These molecules are microscopic organisms closely resembling a portion of a DNA stand. Shortly after RNA became present membranes formed around these stands which continually reproduced at a high rate for about one billion years. They gradually turned into single-celled microbes known as cyanobactria. These microbes released oxygen through the process of photosynthesis. This oxygen was at the time was not the sustainer......

...In this paper I will explain how astronomers determine the composition, temperature, speed, and rotation rate of distant objects using various methods. I will explain the properties of stars. I will also summarize the complete lifecycle of the Sun and determine where the Sun is currently in its lifecycle.Light is a type of energy. Light behaves like a wave because it acts as a disturbance in the magnetic and electric field of space. Light can behave as a particle, because it sends all its energy to one place. A particle of light is called a photon. Photons can be absorbed into objects, bounce off objects, or fly through space. Scientists use the electromagnetic spectrum to organize and explain all types of electromagnetic energy that exist throughout the universe. Electromagnetic waves are organized in the electromagnetic spectrum according to their wavelength from the shortest, which are known as gamma rays to the longest which are known as radio waves. Electromagnetic energy is created by vibration. The vibration produces waves that carry energy. Each magnetic wave emits a different level of energy. These energies travel silently at the speed of light and produce a signature wave with a unique range of length, energy and frequency that scientists can identify and measure. One way that the energy of an electromagnetic wave is measured is by measuring its frequency. Frequency refers to the number of waves a vibration creates during a period of time. In general, the higher......

Science of Sunlight and Stars

...Science of Sunlight and Stars SCI/151 May 16, 2011 Troy Mazely Science of Sunlight and Stars Light is used in many ways, and is a form of energy that can be created, travel through space, and be absorbed. Light can react as a particle, because it sends all its energy to one place. A particle of light is called a photon. Photons can be absorbed into objects, bounce off objects, or fly through space. Over the course of a million years, clumps of particles will grow into what is called a “protostar” and draw in more gases and grow even hotter. This is how stars are formed and is a point in a star’s life. Astronomers determine composition, temperature, speed, and rotation rate of distant objects with a tool called a spectroscopy. When a star gives off light and the light splits by prism, the spectral pattern reflects a star’s composition. All stars are 95% hydrogen, so the variations in composition expose its age, luminosity, and origin. Composition of ages can be determined by observing the light of a star. The temperature of a star can be determined from its color and its spectrum. All stars have different colors because of its light radiation. Another way to determine the temperature of a star is to examine the spectral lines in the starlight. “Because we sometimes describe light as an electromagnetic wave, the complete spectrum of light is usually called the electromagnetic spectrum” (Bennett, Donahue, Schneider, and Voit, 2009). This is used to explain all......
