Scientists have known of hundreds of years that sunspot activity waxes and wanes over a cycle. In the 1970s scientists discovered that the sun periodically blasts electrified gases into space in huge outburst called coronal mass ejections, or CMEs. This project asks the question: Do CMEs follow the Solar Sunspot Cycle? In this project, the independent variables consist of the sunspot and CME values over the years, the dependent variables consist of the years and amount of values observed, and the control is the amount of months in a year.We know that the sun is the ultimate source of energy for most life on Earth. Sunlight warms the atmosphere and supplies the energy that plants use to grow. Did you also know that the sun sometimes releases …show more content…
When CMEs are directed towards Earth, they can generate auroras, the spectacular atmospheric displays also known as “Northern lights” .CMEs can not only put on a spectacular light show, they can also wreak havoc with Earth-orbiting satellites and sometimes even ground-based electrical systems. CMEs were discovered in the early 1970s, although their existence had been suspected for a long time before that. The Solar and Heliospheric Observatory (SOHO) satellite has been observing the sun in unpreceded detail since its launch in 1995. Sunspots were first discovered by Galileo Galilei in 1612, when he noticed dark patches in telescopic images of the sun. Galileo made regular observations of sunspots and was able to prove that he was seeing features on the surface of the sun, which moved as the sun rotated. Galileo was not quite sure of what these dark patches were, though. What is a sunspot anyway? The SOHO Explore Glossary define it as a “Temporary disturbed area in the solar photosphere that appears dark because it is cooler than the surroundings. Sunspots consist of concentrations of strong magnetic flux. They usually occur in pairs or groups of opposite polarity that move in unison across the face of the sun as it
In “The Warmth of Other Suns” by Isabel Wilkerson, the three main characters that the story follows face a great deal of inequality and racial prejudice in both the Jim Crow south that they left and the north that they fled to. Through their stories, as well as the excerpts from Wilkerson that serve to dispel some of the common myths and to explain some of the inequalities that others faced, one is able to make many connections between the problems that Ida Mae, George Starling, and Richard Foster, among many others, faced in their time and the obstacles to equality that our society still to this day struggles to overcome. A large reason as to why these obstacles still exist is that many have preconceived ideas about African Americans and African American Communities. However, numerous obstacles still survive to this day as a result of certain racist ideas.
From the book The Warmth of Other Suns, the author Isabel Wilkerson writes of the economic disparity and the abject poverty suffered by African Americans during the reconstruction. “Sharecropping, slavery’s replacement, kept them in debt and still bound to whatever plantation they worked. But one thing had changed. The federal government had taken over the affairs of the South, during a period known as Reconstruction, and the newly freed men were able to exercise rights previously denied them. They could vote, marry, or go to school…even college set-up by northern philanthropists, open businesses, and run for office under the protection of northern troops.”
Cosmic rays are high energy charged particles, originating in outer space, that travel at nearly the speed of light and strike the Earth from all directions. The term "cosmic rays" usually refers to galactic cosmic rays, which originate in sources outside the solar system, distributed throughout our Milky Way galaxy. However, this term has also come to include other classes of energetic particles in space, including nuclei and electrons accelerated in association with energetic events on the Sun (called solar energetic particles), and particles accelerated in interplanetary space.

There can be several solutions to the puzzle. One is that we do not understand the Sun well enough.
Today many patterns including real estate sales to fluctuations in the climate have been attributed to the cycle of sunspots. These fluctuations may be an explanation of the decline of Sun worship in India due the increased sunspot activity during the time of the Medieval Maximum. Throughtout history these fluctuations have been omens (e.g. a slave revolutionists incited a riot when he interpreted the site of a large black area on the Sun as the black taking over the white) (Schaefer 38). There are also modern examples of solar fluctuations affecting the Earth like the delayed launch of the Hubble Telescope (Schaefer 38) and the disruptions in electrical and radio technology during solar flares due to increased activity of sunspots at the last solar maximum in 1989.
Copper Sun is a book about a fifteen year old girl named Amari who was stolen from her village by white slave traders, and lived a horrible life as a slave until she finally escaped.
The Middle East is made of several countries including Israel/Palestine, Syria, Turkey, Liberia, Egypt, and many other countries of the Arabian Peninsula (The Definition of Middle East). There has been several conflicts all over the Middle East that has yet to resolved or cover in the media. In several countries, such as Israel/Palestine could not move from their past, which result in multiples wars/conflicts. The rest of the world sit back as they do not know what’s going on in the Middle East as the media are feeding the audience bias. Therefore, the Middle East is going to fall apart unless the UN or any international courts take action.
The cause of global warming has been a debate between scientists and experts for numerous years. In fact, Svante August Arrhenius, a Swedish chemist, first predicted global warming would occur in 1896 (Harris 16). Researchers who agree it is naturally caused insist the greenhouse effect has many natural causes. Others agree that the cause of the Earth’s increase in temperature is just part of a continuous cycle. These researchers argue that solar activity plays a huge role in the issue of global warming. Therefore, based upon the myth of the greenhouse effect, cyclical patterns, and research on solar activity, global warming is not a man-made dilemma.

Our sun is the central pivot point to which or entire planet and solar system is built around. With out it all life on our planet would cease to exist. Within this paper we will explore how our Sun and solar system formed and came to resemble what we see today.
A solar storm refers to space weather involving solar activities like solar flares and coronal mass ejection. Although most solar storms may only have minor effect on the Earth, a particularly strong one like the 1859 Carrington Event is likely to cause damage of spacecraft and satellites, as well as radio and electricity blackout of large regions on the Earth. In the age that people’s lives are greatly dependent on electronic and telecommunication technologies, our modern civilization is under a constant threat posed by a hazardous solar storm. This paper will examine a few past solar storm observations and attempt to analyze the effects of the major components of solar storms on human technologies and people’s lives.
In 1910, Arthur Eddington, a British Astrophysicist, discovered solar winds. Solar winds are basically a continuous flow (they are never ending basically) of particles from the sun. They are also known as stellar winds. Their usual way out of the sun is the coronal holes. Their main cause is an expansion of gases in the corona, which is the outer layer of the sun. The idea that the corona is plasma was thought of by Richard C. Carrington. The temperature of the corona is 2,200,000 degrees Celsius. It is so hot that not even the sun’s gravity can contain it. It heats gases and makes them expand. The gas items run into each other as they are heated. As a result, they lose their electrons. Then, the atoms become ions with a positive charge, the electrons and ions (which are mostly Hydrogen ions) make up the solar wind. The velocity of solar winds goes from 250 to 1000 kilometers every second. It has a density of 82 ions for every cubic inch, or 5 ions per cubic centimeter. Solar winds are the cause of many occurrences in the solar system like Mercury having no atmosphere, and Venus’ acidic, radiation filled clouds. They are also known as electrically charged hurricanes.
I am certain that all have heard of the terms greenhouse gases, fossil fuels, and global warming. Have you ever questioned what will happen if nothing is done about the environmental problems facing the world today? What if I answer you that, we can merely use the power from the sun to power up our entire planet without the use of harmful energy sources, which affect our atmosphere? The power from the sun is what we call solar power. Solar power is the energy that comes from the sun as light and heat energy, and then it is later converted into electrical energy through solar panels (Nelson, 2008).
The Earth captures around 342 W/m2 of energy from the sun. This energy is in the form of solar radiation, which the atmosphere reflects about 77 W/m2 and will absorb around 68 W/m2 of solar radiation annually. Therefore, the Earth’s surface is receiving, on average, about 197 W/m2 of solar radiation annually. This amount of energy received is roughly more than 10,000 times the amount of all energy humans consume per year. This energy can be used to produce electricity or heat. This energy source is not being used to it’s potential considering how much effort would come into effect to store and transport this energy.
