Multilayered Structured Sun

“The sun is the heart of our solar system” (NASA Solar System Exploration) which is located at the center of the solar system. The sun has a radius of 432,168.6 miles. You would need 1.3 million Earths to fill up the sun. But the sun is not the largest star there are several that are much larger. The sun is the closest star to Earth which is around 93 million miles. The sun is like a big ball of gas. “In terms of the number of atoms, it is made of 91.0% hydrogen and 8.9% helium.” (NASA Solar System Exploration). But if you measure by mass the sun is made up of “70.6% hydrogen and 27.4% helium.” (NASA Solar System Exploration). Gravitational attraction which is made by pressure and temperature in the core holds together the sun. There is three main layers in the sun which are the core, the radiative zone, and the convective zone. Inside the core temperatures can reach 27 million degrees Fahrenheit

2. Discuss how we are able to feel the sun's heat and see its brightness?

14. Different levels of brightness are due to different levels of heat, and different distances.

In this paper I will explain how astronomers determine the composition, temperature, speed, and rotation rate of distant objects using various methods. I will explain the properties of stars. I will also summarize the complete lifecycle of the Sun and determine where the Sun is currently in its lifecycle.

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.

Sunspots are dark spots on the Sun caused its magnetic field. The spots are dark because they are cooler than the area of the Sun that surrounds them and are often as big as the Earth.

During this unit in my astronomy class, one thing that I found fascinating was sunspots. A sunspot is basically a patch that occasionally occurs on the surface of the sun, and appears darker by contrasting with it’s surroundings. Human’s have known about sunspots for a quite a while now, even all the way back to the fifth century B.C., when the Chinese were able to observe dark areas on the sun. However, it wasn’t until the year 1610 when there was a real break through. Four men, all of which no one is particularly certain who observed sunspots first, were able to see these blemishes on the sun through telescopes. These men were Galileo Galilei, Johannes Fabricius, Christopher Scheiner, and Thomas Harriott. All through their own independent studies, they recorded the changing shapes and locations of sunspots. Further advancement for study on sunspots began in 1749, when scientists began daily observations in several observatories. Continuous observation began in the year 1849.

Sunspots are generated by strong and dense magnetic fields, and these magnetic fields are caused by flowing plasma that gets tangled and moves through the photosphere. [1] However, it is not actually sunspot activity that effects the Earth’s power grid and satellite communications, [2] but rather the solar flares and coronal mass ejections (CMEs) that can be caused by sunspots that cause problems. [3]

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

The sun's many magnetic fields distort and twist as our parent star rotates on its axis. When these fields become knotted together, they burst and create so-called sunspots. Usually, these sunspots occur in pairs; the largest can be several times the size of Earth's diameter.

Our earth is in the sun’s habitable zone, which means it is in the perfect spot to receive all of the sun’s energy. This entails the light and heat which is very important for chemical reactions to occur. The sun is able to create so much energy because it is a massive fusion reaction. This is also known as nuclear fusion. Nuclear fusion releases a very large amount of energy which is in the form of light and heat. To get all of the energy that the sun holds to the earth involves some very important steps. In the end, this energy essentially comes from the sun’s layers. Each layer plays a very important role, which is making sure the energy can get where it needs to go and is able to support life. The core is the only part of the Sun that

Sunspots are temporary irregularities in the sun’s photosphere associated with a relatively more intense magnetic field (George Hale). Sunspots share a number of similar features. They:

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.

The sunspots follow a cycle of eleven years. The number of sunspots varies monthly from zero to the hundreds. During the eleven year cycle there are periods called solar maximum and solar minimum where the number of sunspots reaches its peak or low. At the time of solar max the Sun’s magnetic poles reverse. The north magnetic pole switches to extend through the southern hemisphere and the south magnetic pole extends through the northern hemisphere. In fact the Sun reached its solar max in February of this year

     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.
