STARS The magnitude scale was invented by an ancient Greek astronomer named Hipparchus 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
self destructive explosions. Stars, through their violent birth to their even more violent death, manufacture the elements necessary for life. These giant balls of superheated gas begin their lives as nebulas, slowly evolving into the magnificent lights we see burning in the night sky and eventually dying by gravity, the same force that helped create them, scattering the plethora of elements they created across the universe, allowing life as we know it to occur. Stars are the source of human existence
STAR: One such study is called Tennessee’s Student Teacher Achievement Ratio (STAR) Project. This study was made in an effort to find out the best number of students for one teacher to teach. “STAR was a large-scale, four-year, longitudinal, experimental study of reduced class size” (Reduce Class Size Now, 2003 p. 1). This project kept track of 11,600 Tennessee students in 76 schools (Small Class Size, 1999). This study found out a lot of ways that small classes are beneficial. STAR “reported
From the Ancient Greeks and Egyptians, to the Three Wise Men and modern day Muslims, the stars have always been of great cultural and spiritual importance for people all across the globe. The constellations have meanings that exemplify different types of people and things in the natural world. These stars are the “blueprint” of humanity, giving mankind a better understanding of the world and themselves through the astrological birth chart. There are three vital references of the astrological chart
The beautiful twinkles of light in the night sky are stars. How did these sparkles of light come about? What role does physics play in the life of a star? To understand the physics of stars we must take a look at gravity, nuclear fusion, supernovae, and neutron stars. Gravity is important in the formation of stars. A protostar, the earliest stage of a star, is formed from dust and gas from a nebula clumping together. The gravity pulling in is greater than the pressure pushing out. As more matter
A star is a self-radiant divine body consisting of a mass of gas held together by its own gravity. The birth of a star begins inside a molecular cloud. Stars form inside these somewhat dense concentrations of interstellar gas and dust. The process of star formation has long been a mystery because of viewing limitations. Large amounts of small solid particles blocked our view of the stars which are beyond the molecular cloud. Infrared technology now provides some insight on how a star is formed
Jersey, to live with their mom. After moving to New Jersey, Star started to shine in school. She always held the top grades throughout school and after graduating from a parochial school she enrolled in the American University in Washington, DC. While at American, Star sang in the gospel choir and joined Alpha Kappa Alpha, a very prestigious African-American sorority. She was a popular student on campus and was given the nickname of “Star.” It was at American that Jones was diagnosed with inoperable
‘There are more stars than all of the grains of sand on earth.’(Star Facts, 2005:1) Looking up at the sky on a vibrant night, the vision is naturally lit one with millions of vivacious, glistening stars. The tenacity of this essay is to explore the lifecycle of a star, thence, signify its manifestation in the universe. A fundamental part of our universe is stars. Hence, these miniature luminous forms are essentially very immense in magnitude and it is merely due to their substantial distance from
Stars lifecycles span from millions to billions of years. Over that time many different events occur and vary from star to star. These events include exhausting their hydrogen core, expanding, and “death; which can encompass the star turning into a neutron star or a black hole. Also the lifecycle of a star directly effects earth. Our solar systems star, the sun, will eventually expend its fuel supply, die, and eventually expand until it reaches Earth. According to Andrew Fraknoi “the Greek Philosopher
In the endless expanse of intergalactic space, stars are in every stage of being born, radiating huge amounts of energy, transforming and dying. When one finds out more about how stars are formed, what they are made of, and how they die one cannot help but to be awed by the complex processes and vast transformations that take place in the lifecycle of a star. A star's life begins in a nebula, which is an interstellar cloud made up of dust, hydrogen and helium gas, and plasma. Nebulas have been called
Stars are born within clouds of dust and swirling wind in our atmosphere. The turbulence within these clouds creates enough gravitational force between the gas and dust that it begins to collapse upon itself and becomes more dense and hot further into the cloud. The cloud continues to collapse, collecting dust and gas around the hot center which is called a protostar. (http://science.nationalgeographic.com) Protostars are not hot enough to emit visible light in their early stages, but emit infrareds
The Lifecycle of Betelgeuse The Star Betelgeuse is classified as the ninth brightest star in the night sky and is the second brightest star in Orion's’ constellation. Betelgeuse is a very unique star in the sky when it is compared to other stars.Betelgeuse is classified as a high mass star. Some introductory facts about the star include its luminosity, which is 140,000 suns, temperature is 3,488 Kelvin, its distance from the sun is 640 light years, radius compared to the sun is 667 times the sun
reaches its greatest height in mid-January, and drops below the western horizon in late March. Moreover, Orion is among the most spectacular constellations, with many bright stars and scores of fascinating stellar objects. It can be quickly distinguished by four bright stars arranged in a sloppy rectangle around three stars set in a line—the famous “belt” of Orion. Legends have described Orion's presence in the
Star Wars and Religion Methodology In conducting my research on Star Wars, I wanted to make sure that I kind of found a variety of sources. I decided to do my field report on Star Wars originally because I was aware that I needed to include an interview component in this report. I immediately thought of my R.A., who just happens to be an incredibly huge Star Wars fan. I knew that I would have to investigate some element of the movies and religion has always been a very controversial topic
Comparing the Stars of Bright Star and Choose Something Like a Star Keats "Bright Star" and Frost's "Choose Something Like a Star" although similar in their address to a star differ in form, tone and theme. The latter contains an illusion to the former that brings Keats' themes into the poem. In order to compare these poems it is necessary to look carefully at their themes and constructions. "Bright Star" is a sonnet in traditional iambic pentameter. Its tone is elegiac as it celebrates the woman's
Star Wars vs. Star Trek Throughout the past two decades, two science fiction cult classics have rivaled each other. Both have strong followings of loyal fans that live and breathe these classic tales. Lunch boxes, t-shirts, masks, bed sheets, and figurines are only some of the merchandising offspring of these two epic films. Star Wars and Star Trek certainly share many similarities being the benchmarks for the genre of science fiction movies. While the similarities are not difficult to
as fond of riches to rags – or let’s say, stardom to failure. What happens when a successful young performer becomes a has-been star? The high-profile troubles of celebs like Michael Jackson and Gary Coleman reinforces the truth that nearly every kid who has worked in the entertainment industry has struggled as an adult. Although some may argue that several child stars have gone on to have stable and successful careers as adults, our contention here is that a lot of celebrities who were exposed
Life Cycle of a Star Our Sun is a perfect example of a star, and there is an incredible amount of stars in the Universe. It is a star among hundreds of billions of stars within our Milky Way Galaxy, and our galaxy is one of billions of galaxies 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
some things may not be connected, or even four light years away, like stars and humans. They still are very much the identical. Humans are born, while stars are created. Then, a Humans work through their lives: school, to a job, or work, or on personal work . On the other hand, a star's work is just being. But, through every life cycle comes death. While humans and stars die for differential reason and ways, humans and stars follow the same pattern, but just with different details. All things
Cosmic Nurseries - Mommy, Where do Stars Come From? Since my entire thesis for this paper is about how a star is born, I guess the first thing I should start out with is by telling you exactly what a star is. Stars are self-luminous gaseous spheres. They shine by generating their own energy and radiating it off into space. The stars' fuel for energy generation is the stuff they are made of --hydrogen, helium, carbon, etc. -- which they burn by converting these elements into heavier elements
