Sunspots And Radiation

Isabel Wilkerson is an African American Howard University journalism graduate writer and the first black woman in the history of American Journalism to win a Pulitzer Prize. Among her notable works is the novel “The Warmth of Other Suns”. The novel The Warmth of Other Suns was about the Great Migration which occurred between the years 1915-1970 and this was the movement of approximately seven million Black people out of the Southern United States to the North, Midwest and Western states from 1916 to 1970. Blacks migrated to escape widespread racism in the South, to seek employment opportunities in industrial cities of the North, to get better education for their children, and to pursue what was widely

The foremost differentiation between solar flares and coronal mass ejections (CMEs) is the scale on which they transpire. Solar flares are rather little and local, occuring in the low solar atmosphere, near sunspots, where magnetic field lines are concentrated. CMEs on the other hand are huge. They can even be bigger than the sun itself!

1. The earth’s sun is a star, it generates heat and light through nuclear fusion.

UV radiation, such as that from the sun can be very harmful. It has been shown to cause many different mutations within cells, leading to issues for the organism such as death or disease. One of the most prevalent sources of UV radiation for humans is the sun. It’s very important for us to know the extent of cellular damage that can be caused by this radiation, as to know how harmful the sun’s rays are to us as humans. One way that the damage caused by the suns radiation can be tested is through the model organism yeast. For this lab, we exposed two different strains of yeast to UV radiation to test its affects. One strain was able to self-repair, while one was genetically altered so that it could not. Observations were recorded at

The life cycle of the Sun starts like all stars with a cloud of dust and gas made up of mostly hydrogen. If the cloud cools, it will shrink because of the gravitational pull between the particles

This paper talks about the solar flares and how they go on to cause global warming. Global warming has been an ongoing phenomenon and there are many reasons it has occurred. Apart from the green house effect, global warming could have been due to the solar flares that have occurred. Different researches and theories regarding this matter are discussed in the paper.

1. Sunspots: these regions are darker and cooler than the rest of the suns photosphere; they are caused by magnetic fields that protrude at that area of the visible surface.

It is no secret that the earth’s sun is “special” to say the least. Some would say it was designed to be unique to help sustain life on planet earth. However, other nearby stars were not designed to sustain life. One example would be the star Proxima Centauri. This star recently had a short increase in radiation, known as a flare. This flare caused the star to become a thousand times brighter for ten seconds. Earth’s sun also has flares, but they are much smaller. When Proxima Centauri is at its brightest point it is still ten times brighter than our suns largest flare. This is just one example of how special our sun really is.

Solar flares are eruptions of energy from the sun’s surface. Quickly reaching temperatures of 10 to 20 million Kelvin, these flares can rise thousands of kilometres above the chromosphere, and can release energies of up to 6 x 1025 joules (equivalent to “the energy of a few million volcanic eruptions on the earth”) [4]. Solar flares have three classifications: X, M, and C-class. X-class solar flares are the largest of the three, and also have the largest impact on Earth, causing long-lasting radiation storms in the upper atmosphere, and causing radio blackouts. M-class solar flares are less powerful than X-class, however they can still cause the occasional radiation storm, and brief radio blackouts in the polar regions. C-class are the smallest of them, and barely have any impact on Earth. [5]

Sunspots aren’t that complicated they’re really just dark spots on the sun’s surface. Now these sunspots have a strong magnetic field and always in motion. The sunspots take around 27 days or so to rotate, but we can only see, so much from the Earth’s surface, but for now 27 days would be our best answer. Now you probably haven’t heard about solar maximum or minimum, but they are also related to the topic of sunspots. They really just mean if their is no sunspots, solar minimum, and if their is the most we could possibly see, solar maximum, and both would be seen from earth, not space. Their is this thing where the sun envelops the Earth with energy, such as light and these elecrtically charged magnetic fields, or particles. This is what people call solar weather and after the earth is bathed with the forms of energy, their is only an effect that affects us durring an auroral event. If solar weather hits during an auroral event power grids may get

Coronal Mass Ejection also known as CME is usually created around the sun’s surface by magnetic reconnection. CME is a large bubble of gas and magnetic field lines that are emerged from the sun. There isn’t a full proven understanding of how CME’s occur but Astronomers have come to a theory that because the sun is a fluid, the turbulence gets kinks that get shot out into space in any direction as a superheated gas. The gas that is ejected from the sun is made of protons and electrons carried through solar winds. This gas is known as plasma and can accelerate over 1 million miles per hour and reach Earth that is 93 million miles away in less than 4 days. When the sun is most active Coronal Mass Ejections can happen multiple times per day however, it usually occurs once every 5 days.

Sunspot activity follows an 11-year cycle known as the sunspot cycle. The times of their peak activity correspond to times of increased radiation received by earth. The number of sunspots varies within the 11-year cycle, with some cycles showing more sunspot activity than others. They are not permanent features of the sun, and can last from a few hours to a few months.

Solar flares are cyclical, usually over a period of eleven years. There are three basic stages to a solar flare. The first stage is the precursor stage, where the release of magnetic energy is triggered. In the second or impulsive stage, radio waves are emitted. During the third or decay stage, the gradual build up and decay of soft x-rays can be detected.

     Sunspots, where most solar flares occur, are dark patches on the surface of the sun. This is where the gas of the sun is not so hot and causes it to take on a different color. A typical sunspot is about 22,000 miles in diameter and the number visible sunspots from satellites are about 5 to 100, it varies.

The narration of the film In the Heat of the Sun is bathed in masculinity. The story basically follow the male protagonist and narrator, Ma Xiaojun, his gang of male friends, and the masculine world they inhabit. There are only three notable exceptions to a film that consists almost entirely of men and boys: the protagonist 's nameless mother, and two girls his age: Yu Beipei and Mi Lan. Both girls are amongst his cohort, and are therefore the main focus of the whole gang’s adolescent desire. However, the overwhelming masculinity of the movie leaves little room for the exploration of the female characters’ identities and personalities. In fact, perhaps unintentionally, the film In the Heat of the Sun objectifies the women, and reveals how
