The Sun Essay

Decent Essays
Located 92.96 million miles away lives one star that is the reason for human existence. The Sun is the most important energy source in our solar system. It accounts for so many things such as photosynthesis. The magnetic field is our source of protection. The Sun is the creator of many optical effects such as the auroras. Our planet earth is heated by one huge ball of gas, its formation is a mystery and the impact it has on planet earth is drastic.
The Sun is in the center of our Solar System and is the most important source of energy. The formation of the sun is no mystery to modern day scientists. Space is filled with gas and dust and there is a presence of hydrogen and helium. The sun was created from the remnants of a dead star. Waves

The Sun has its own atmosphere that made up of three distinct layers (photosphere, chromosphere and corona). The innermost layer of the Sun’s atmosphere is the photosphere. The photosphere is the coolest of the three layers with a temperature of about 10,500 degrees Fahrenheit. This layer extends from the sun’s surface to a few hundred-miles above the surface. Convection currents consisting of gasses from the sun cycle constantly. These currents travel to the photosphere where they release heat. As the gasses cool, they descend back toward the center of the sun where they are reheated. The cycle continues as gas is heated and cooled. This is the process of convection. The next layer, the chromosphere is located just above the photosphere. It is approximately 1,200 to 1,900 miles thick. The chromosphere is much hotter than the photosphere with an approximate temperature of 90,000 degrees Fahrenheit. The chromosphere is characterized by plages and flares. Plages are found in the lower level of the chromosphere nearest the photosphere. Plages are denser with higher temperatures than the surrounding areas. They occur around the same areas as sun spots and appear as bright patches. Solar flares occur within the chromosphere. These magnetic storms contain a tremendous amount of energy. They can travel thousands of miles about the suns surface. The outermost layer of the Sun’s atmosphere is the corona. The …show more content…
Magnetic fields reach great distances. They are strongest at the source and become weaker as they move farther from the source. Because of this phenomenon, the magnetic field produced by the dynamo effect can be detected far into space. The magnetic field lines that surround Earth are asymmetrical. The lines found closet to the sun are close together because of the influence of solar winds. The lines protecting the Earth are much more elongated and less dense because they are not as influenced by solar winds. Charged particles along the lines become trapped which leads to the formation of Earth’s magnetosphere. The magnetic field is able to change for either a short or long period of time. A short-term change occurs after a disturbance from sunspots. Charged particles from Earth’s atmosphere are launched into space causing disturbance only while they are circulating. A long-term change is characterized by a complete reversal of the Earth’s magnetic fields. The reversal happens on average every 500,000 years. The last known reversal was 700,000 years ago (“Earth’s magnetic field,” 2014). The magnetic field is not the only fascination of our

    Solar energy is generated from the sun. Solar energy is created by nuclear fusion that takes place in the sun (Buettner, 2015 ). Nuclear fusion occurs when protons of hydrogen atoms collide in the sun’s core and fuse together to create a helium atom (Buettner, 2015 ). The process is known as PP (proton- proton) chain reaction which emits excessive amounts of energy. In the core of the sun it fuses about 620 million metric tons of hydrogen every second.…

    Astronomy in Yosemite The Sun The sun is a star located at the center of the universe, and without it, there would be no life on Earth. It is the most important source of energy for humans as it provides us light, heat, and more. It can reach surface temperatures of about 5,276 degrees Celsius, and 10,340 degrees Fahrenheit. The composition of the Sun changes slowly as hydrogen is converted into helium in its core; however, it is currently made up of around 70% hydrogen, 28% helium, and less than 2% of other metals.…

    The Earth is a part of the solar system and it has been influenced by its elements since it was formed. The solar system was formed from a large nebular cloud. This nebular cloud began to spin producing energy due to the collision between particles. The composition of these colliding particles included metal-rich fragments such as iron meteorites, rocky fragments such as stony meteorites, and icy fragments such as comets. The solar nebula grew hotter and denser, forming a disk of gas and dust at its center.…

    A Raisin in the Sun Title Controversy; Emotion v. Plot Titles are not to be taken lightly as they are what a reader keeps in mind throughout a piece. “Mother to Son” and “Harlem” are both written by Langston Hughes and portray the struggles of maintaining a dream during difficult times. “Mother to Son” uses the extended metaphor of a staircase that parallels the struggles and overall actions in the play A Raisin in the Sun by Lorraine Hansberry, while “Harlem” uses graphic images in order to form a well developed motif and mood of the idealistic dream, which is matched in the play. As a title is meant to add to a piece of work, and enhance a certain idea the author deems significant, Lorraine Hansberry contemplated using the title The Crystal…

    Many cultures throughout history have referenced to distinct patterns in the sky formed by stars. These patterns have been called many things but now scientists refer to them as constellations. Often times in our society we forget what a privilege it is to have tracking tools and measuring devices but 5000 years ago they used these constellations to track time and be able to tell where they are. Constellations have been seen as specific animals or figures that are then told with myths. STILL NEED TO FINISH…

    Classical and Enlightened Absolutism in France Comparison The motherland of absolutism in Europe of the 17th century is considered to be France. The absolute monarchy spread the idea of the state as a public good, a sovereign legal person. There was no longer a place for patrimonial ideas, the state as the property of the ruler. In the days of Richelieu, the first minister of king Louis XIII,(1585 -1642) and especially Louis XIV (1643-1715), the absolute monarchy attained the bloom.…

    Although much progress has been made in recent years in helping LGBT Americans not be a marginalized group, the way Noah is treated like an alien in I’ll Give You The Sun illustrates how being LGBT still puts you into a marginalized group. Being in a marginalized group means it’s less likely that you were to be accepted, get jobs, find friends and partners, and even makes it more difficult to do the things you love. It’s much more likely that you will be criticized and discriminated against if you are of the LGBT group than if you were straight. This is because it is not universally accepted to be LGBT at this point. Being a member of the LGBT community puts you into a marginalized group which means you would not be accepted as a member of…

    The Life and Works of Lorraine Hansberry Alveda King once stated, “Racism oppresses its victims, but also binds the oppressors, who sear their consciences with more and more lies until they become prisoners of those lies. They cannot face the truth of human equality because it reveals the horror of the injustices they commit” (Brainy Quotes). In Lorraine Hansberry’s play, A Raisin in the Sun, the Younger family lives in South Side Chicago and faces racial discrimination. The entire family experiences different hardships over the years. While reading Hansberry’s drama, the audience can better comprehend the content with the help of sociological and biological criticisms.…

    Sunspots have been observed since the time of Galileo when he used the telescope to observe the sun. They are visible through a telescope as darkened spots on the sun caused by an area of extreme magnetic activity and dramatically lower temperatures (compared to the average temperature of the sun). The sunspots are approximately 2,000 degrees’ kelvin cooler than the photosphere which is why they appear darker against their hotter surroundings. The diameter of a sunspot varies from approximately 700km to over 7,000km and has a magnetic field of up to 0.4 tesla, which is extremely high. Sunspots are caused by locations of magnetic field disruptions inside the sun which prevent a lot of heat from reaching the surface, hence the cooler temperatures.…

    The video we watched in lab, “Life and Death of a Star,” gave us incredible information regarding the life cycle of a star. There are billions of stars out there and in our galaxy, we have about four billion. Stars, which are ignited by the power of the atom, burning with light, heat and wrath, stars are anything but peaceful. They collide, devour each other, and explode in enormous supernovas. These “supernovas” are known to be the largest explosion in the universe.…

    Nasa’s spitzer and Hubble space telescopes have discovered a massive galaxy creating more and more new stars. The way that this massive cluster has been formed so quickly is by feeding off gases from other galaxies. Tracy Webb of McGill University explained that usually a star in the center of a galaxy is old and dead, but this new cluster within this rare galaxy is creating new stars very quickly by merging with other smaller galaxies. Clusters are families of galaxies bound together by the ties of gravity. This new cluster being studied is referred to as SpARCS 1049+56.…
