features of the sun: sunspots, solar flares, and aurora borealis. At the beginning of the cycle, the magnetic field is weak and there are very few sunspots; later, at the peak of the cycle, the magnetic field is strong, and there are many sunspots. Sunspots are relatively cool areas that appear as dark patches on the face of the sun. They occur where magnetic field lines are twisted below the surface. The period of time when the magnetic field is strong and there are many sunspots is called a solar
Sunspots Our Sun continuously converts hydrogen into helium and with this process it provides the essentials for life processes. In doing this it controls “our climate, provides light, raises tides, and drives the food chain” (Schaefer 34). Our Sun also has influenced many beliefs now and in the past. History has documented Sun worshipping religions while many current societies use solar calendars (Schaefer 34). Because the Sun is so influential, imperfections of the Sun, such as sunspots
can reach about 15 million degrees Celsius? This bright star has many significant happenings. These interesting occurrences include sunspots, solar winds, coronal mass ejections, and solar flares. Sunspots are cool, dark-colored regions of the photosphere related to a shifting magnetic field inside the sun. However, sunspots are only dark in our perspective. A sunspot removed from the bright background of the Sun would glow brightly. Solar wind is the radiation of heat and a steady stream of charged
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
orbiting it: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune. Without the sun, we wouldn’t be where we are today. Our star is the closest one to our planet so we are able to observe and study it and its solar phenomenon’s such as sunspots, solar flares, solar winds, and prominences. The sun is 1,390,000 kilometers in diameter and weighs out to about 1.989e30 kilograms. Being 5,800 degrees Kelvin, the sun is so hot nothing can get close enough before it gets burned up. The suns’ core
A star is an orb made up of hydrogen and helium. Stars are formed when a gravitational disturbance, such as galaxies colliding or a supernova explosion, causes molecular gas clouds to collapse. The concentration of gases generates heat and momentum from particle movement in the cloud produces a spinning effect. After approximately one hundred million years, core temperature and pressure reach levels that are sufficient to ignite nuclear fusion, which is what defines a star. A star’s properties
such as the first tank, a helicopter, and even improved the existing telescope. Galilei had many contributions to science as well. He observed discovered sunspots but later was blinded by looking at the sun too much. Galileo's top accomplishment which every one knows him by is his discoveries of the telescope; Earth revolution around the sun, Sunspots, and Venus phases. He was an amazing mathematician, astounding physicist, but he is most known for proving that the sun does not revolve around the Earth
as the famous astronomer, Galileo, who kept a scrutinizing eye on his publications. Although some of Scheiner’s work was misguided, he managed to overcome most of his mistakes and criticisms, and eventually asserted himself as a top authority on sunspots for nearly two hundred years (College, 569). All of Scheiner’s formal education had come by the teachings of Jesuit establishments, where he learned and believed (like most) of the Aristotelian structure of the cosmos. In his later years, he attended
The Sun The Sun is a star, just like the other ones humans can see in the atmosphere at night. The Sun is actually much closer. In fact, our Sun is a somewhat traditional star, it is not too big or too small, it isn’t even that young or really old. Just an ordinary star. However, as a result of the Sun being so close to Earth, Astronomers believe the Sun is the star we can easily study. The Sun contains some basic elements that can be found on Earth. The Sun is estimated at 92% hydrogen and 8% helium
In 1609, Galileo built his first telescope and about a year later. He discovered the Moon, Jupiter’s four largest moons and many new stars. Three of Galileo’s most important works where Letters on Sunspots, The Assayer and Dialogue Concerning the Two Chief World Systems. Galileo’s Letter’s on Sunspots showed of solar imperfections and described axial rotations. Galileo’s The Assayer showed the nature of scientific investigation through observation and mathematics. One of Gal...

He was able to see the moons of Jupiter, the phases of Venus, sunspots, and the moon’s surface. He issued The Starry Messenger in 1610, Letters on Sunspots in 1613 and was put in the position of Mathematician and philosopher to the Grand Duke of Tuscany.

Climate change is a long-term change in regional or global climate patterns. From the mid twentieth century to now, it has mostly been about a significant increase in average global temperatures. Climate change is a major issue in the world today, and a lot of people feel very differently about the cause of it. The common argument about it is whether climate change is a natural occurrence or if the recent increase in temperatures is because of humans. Climate change is a natural cycle in the

The Heresy of Galileo Galileo was condemned by the Inquisition, not for his own brilliant theories, but because he stood up for his belief in Copernicus's theory that the earth was not, as the Church insisted, the center of the universe, but that rather, the universe is heliocentric. Galileo was a man of tremendous intellect and imagination living in a era dominated by the Catholic Church, which attempted to control the people by dictating their own version of "reality." Any person who
Introduction: Astronomy is derived from infancy of human culture--- ancient age. People pay more attention to observe sun, moon and star by positioning their location and making calendar in order to indicate direction, ensure time and season. In some point of view, astronomy is one of the most old subjects in Neurology. Sun, as one of the most vital origins that providing light and ultraviolet rays, is actually an very huge galaxy, its cycle was found by a amateur astronomer, Henry Schwab. In 2010
In recent years, global warming is a topic that has received much attention. It’s is a gradual increase in the overall temperature of the earth's atmosphere generally attributed to the greenhouse effect caused by increased levels of carbon dioxide and other pollutants, which also known as the green house effect. Global warming can negatively affect the earth's delicate ecosystems. It has been linked to dangerous new weather patterns, the extinction of plant and animal species and so many others bad
The Sun The sun is the largest object in the solar system. It is a middle-sized star and there are many other stars out in the universe just like it. Even though it is only a middle-sized star it is large enough to hold over 1 million Earth’s inside if it were hollow. The temperature on the sun is far too much for any living thing to bear. On the surface it is 10,000 degrees Fahrenheit and the core is a stunning 27,000,000 degrees Fahrenheit. But don’t worry we are over 90,000 million miles away
Short Biography of the Astronomers Below: Nicolaus Copernicus: The Helio- Centric Model The heliocentric model is a theory by Nicolaus Copernicus that places the Sun as the center of the universe, and the planets orbiting around it. The heliocentric model replaced geocentrism, which is the belief that the Earth is the center of the universe. The geocentric model was the prevailing theory in Ancient Greece, throughout Europe, and other parts of the world for centuries. It was not until the 16th
earth, space x-rays and thermal imaging equipment are used to observe these huge monsters. A solar flare occurs when magnetic energy that has built up in the suns atmosphere is unexpectedly released. This occurs mostly in the active regions around sunspots. The frequency of solar flares varies from several a days when the sun is active, to one a week during periods when the sun is less active. (ESA, What are Solar Flares) The amount of energy released by a normal sized flare is equivalent to one hundred
electromagnetism. André-Marie Ampére deduced that magnetism is basically the force between electric currents. In 1851, Samuel Schwabe, a German amateur astronomer, announced the discovery of the 11-year sunspot cycle, and in 1859, Richard Carrington in England observed a violent and rapid eruption near a sunspot; 17 hours later a large magnetic storm began. In 1900-3, Kristian Birkeland experiments with beams of electrons aimed at a magnetized sphere ("terrella") in a vacuum chamber. The electrons hit near
