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, the sun could never reach us, at least not yet. The sun is a still a middle aged star and later in its life it will become a Red Giant. In this stage it will get bigger, and closer to us causing a temperature increase and most likely the

The heat and light of the sun come from the nuclear reactions of hydrogen, carbon, nitrogen, and helium. So the sun is just one great big atom smashing, gas creating, nuclear furnace that gives off much appreciated energy. But this is not all that happens on the sun’s surface, some exciting stuff does happen up there every once in a while. Have you ever heard of a solar flare? A solar flare exists after a sunspot has existed for a long time and the magnetic lines of force usually become jumbled. As a result of this jumbling, magnetic energy is stored in the Corona (region of atmosphere above the chromosphere). The energy may be released in a spectacular discharge, which is a solar flare. A solar flare can be as wide as 367,000 miles and as high 500,000 miles out into space. A solar flare is nothing more than helium erupting from the sun like a volcano. 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. How does the sun move? It moves just like earth does, it spins on axis like a top. As earth moves around the Milky Way galaxy, the sun revolves around the center of it. It takes one day for the Earth to spin all the way around on the
However, this has not happened and it’s starting to make secular scientist themselves admit that our sun is special and unique in design, because it does not emit these monster super flares like the ones produced by Proxima Centauri. The question is, could our sun send out such a flare powerful enough to even melt the ice on Jupiter’s moon’s, destroy earth’s ozone layer and even obliterate all our satellites? Well the answer is yes. Scientist have studied other sun like stars in our galaxy and discovered that they produce these super flares about once a century. But, they have no explanations as to why our sun does not produce such solar
Sunspots are temporarily cooler and darker compared to their surroundings, and are only 4500 degrees celsius compared to the regular surface temperature of the sun which is 6000 degrees celsius. They are able to shrink and grow as they move around on the sun’s surface, and are able to get as large as 80,000 kilometers wide. They can last anywhere from a few short hours to a couple of months. Sometimes the sun consists of many sunspots, and sometimes there are very few to none. When very few sunspots are visible this is known as a solar minimum, compared to when there are a large number of sunspots is known as a solar
Way out there in space, there are huge clouds of dust and gas and if one of those clouds of dust and gas is massive enough it's own gravity can causes it to start to collapse. When it collapses, it folds itself towards the center of the cloud, then it get denser and denser and hotter and hotter; eventually the particles of that gas and the dust are made up and brought so close together that they start to stick together. Then they start to fuse, thats the energy source of a star. The star switches and begins to shine. Inside every newborn star, hydrogen atoms are fused together to make helium. This process is called fusion and it creates the energy of every star. A star is a luminous sphere of gas producing its own heat and light by nuclear reactions (nuclear fusion).
At the center of the sun, the temperature is 27 million degrees Fahrenheit (15 million degrees Celsius). As the temperature on its surface rises and falls, the sun boils and bubbles. Particles escape from the star from the sunspot regions on the surface, hurtling particles of plasma, known as solar wind, into space. It takes these winds around 40 hours to reach Earth. When they do, they can cause the dramatic displays known as the aurora borealis. [Infographics: How the Northern Lights Work & Anatomy of Sun Storms & Solar
The most common form of fusion of the sun. This took place by joining 4 hydrogen nuclei which formed helium alongside other substances; these include; 2 gamma rays, 2 neutrinos and 2 positrons. These heat the sun and keep it alive. The same kind of fusion also occurs in other stars in the universe. When the particles fused together in the sun, the mutual gravity gave the particles kinetic energy, which settled, converting to heat.
Sunspots are regions on the surface of the sun, which is called the photosphere. Sunspots are cool, dark and temporary. The surface temperate of the sun is 6000 Celsius and sunspots are about 1500 Celsius. They can last up to hours or even months. Sunspots usually expand and contract as they move across the surface of the sun and can be as large as 80,000 km in diameter. Sunspots are magnetic fields on the sun, which are thousand times stronger than the magnetic fields on the earth. The magnetic field is the strongest in the darker parts of the sunspot, which is called umbra. The field is weaker in the lighter part, which is the penumbra. These are solar "storms", a kind of "burp" where the Sun ejects high-speed and energetic particles, which
Sunspots are dark, irregularly shaped regions at the surface of the sun, typically lasting over a couple of weeks or months. Sunspots are generally cooler than the photosphere that surrounds it, hence why they appear darker. This cooler characteristic is caused by intense magnetic field activity, associated with sunspots, which prevents the convection of heat to the surface.
Solar flares are defined as brief eruptions of highly energized radiation from the sun, but why does this happen? Solar flares occur when magnetic energy is built up, then rapidly released at once, during, the sun gives off generous amounts of X and gamma rays. Strangely enough the energy of a solar flare is ten million times that of a volcanic eruption, but only 1/10th of the energy that comes from the sun every second. There are three stages of solar flares, first, the precursor stage “where the release
Solar flares produce X-Rays for a few minutes or hours and produce more radiation that the total amount of light in infrared or visible light. Not likely for planets near flare stars to have life (102 book). Solar flares are intense bursts of radiation coming from the release of magnetic energy associated with sunspots. They release photons at almost every wavelength in the electromagnetic spectrum (Solar). The Earth is only affected by solar flares when they occur on the side of the sun facing Earth because they are
The Sun was formed about 4.57 billion years ago from a giant molecular cloud, which consisted mostly of hydrogen and helium (highest in Photospheric composition). The formation of the Sun would have been triggered by a shock wave from a nearby supernova. The matter in the molecular cloud would then be compressed to cause certain regions to collapse. As a consequence a fragment of cloud would start to rotate due to the conservation of angular momentum and heat up with the increasing pressure.
Solar flares release 10 million times more energy than a volcano and during times, there are over 20 solar flares a day. They are about as hot as the Sun’s core. A Solar flare/Solar storm is a brief outburst of intense high-energy radiation from the sun’s surface associated with sunspots and causing electromagnetic disturbances on the Earth, as with radio frequency communications and power line transmissions. Solar flares are caused by the sudden release of magnetic energy. The largest ones can release as much as a billion one - megaton nuclear bombs. Solar flares/Solar storms occur anywhere on the sun, the most violent events on the surface of the sun. We are well protected from the effects of the solar flares.
Solar flares can affect us is many ways. Solar flares are when certain energy, electrons,protons, and nuclei release into the solar atmosphere. There are many subjects to solar flares like the stages, features, and how they truly affect us. Sun spots and radiation can in fact, also take place in the unique solar flare process.
The Milky Way contains billions of stars with different ages and sizes. One example of a star which is closest to earth is the Sun. Just like all the other stars the sun is a luminous ball of gas which mostly contains hydrogen and helium and is held together with its own gravity. All the stars produce their own energy by a process called nuclear fusion. Stars life begins in the place what astronomers call the Nebulae. A nebula is enormous cloud consisting of dust and gas; mainly hydrogen and helium. There are three different types of nebulae. The first one is Emission Nebula. Emission Nebulae are usually red and pink in colour because they are filled with hydrogen gas. The Emission Nebula is very hot because of the newborn stars zap there surrounding
The sun is an incredibly dynamic ball of mass and energy at the center of our solar system. The source of the sun 's energy is nuclear fusion; where mass is converted into energy when protons (positively charged hydrogen atoms) smash together at incredible speeds at the center of the sun to form helium. Nuclear forces aren 't the only thing acting on the sun, electromagnetic forces also play a vital role in the sun 's dynamic behavior. Due to the unimaginably high kinetic energy of particles within the sun 's core, electrons are stripped of their atoms, leading to high amounts of charged particles. These charged particles are known as plasma, and they behave distinctly from other generic types
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.
