The Sun is a second generation star, located in the center of the Solar System. It's source of nuclear energy provides the heat that help sustain life on Earth.

These websites gives you a variety of information on the sun, its birth, the missions to it, its sunspots, its death, the probes, the suns age and many other fun facts about it. The information will help you gain great perspective of the sun and all that it does for us. Helps you to know more and really does teach you things about it that you never truly learned/knew. Some websites says the same things but in different ways and some says the same exact thing but the great thing of it is that you now know more about the sun.

Summary About the Sun:
The Sun is our closest star. It is a member of the Milky Way galaxy. The Sun is a yellow dwarf star, which means it is a medium size star. It is believed to be over 4 billion years old. The Sun spins slowly on its axis as it revolves around the galaxy.
The center, or core, of the Sun is very hot. A process called "nuclear fusion" takes place there. Nuclear fusion produces a lot of energy. Some of this energy travels out into space as heat and light. Some of it arrives at Earth! Streams of gas particles known as the solar wind also flow out from the Sun.

On the Sun's surface, we can see storms. We call these storms "sunspots" because they look like dark spots on the Sun's surface. The Sun also produces big explosions of energy called solar flares. These flares shoot fast moving particles off the Sun's surface. These particles can hit the Earth's atmosphere and cause a glow called an aurora.

This website gives you information about the sun. Its form and color and many interesting facts you may already know or do not know at all. It gives a breakdown of the sun and can teach you many, many things.

StarChild has been developed primarily by a duo of middle school teachers who generously volunteered their time and talents to making the StarChild site what it is. Here is a little more about them: Elizabeth "Libby" Truelove

This site is believed to be for school aged people. I believe that even younger children can understand it.
There is more information on the site if you click on other links. It even includes a glossary for other names and information about planets and other stars.

The Sun as seen in X-rays
Summary of the suns x-rays:

(from the Yohkoh satellite)
The Sun is a star. It is a rather ordinary star - not particularly big or small, not particularly young or old. It is the source of heat which sustains life on Earth, and controls our climate and weather. It is the closest star to Earth, and the most closely studied. From it we have learned a great deal about the physical processes which determine the structure and evolution of stars in general.
Below we discuss the regions of the Sun's atmosphere which we can observe and measure.
The Sun's Outer Layers
Only the Sun's outer layers, collectively referred to as the solar 'atmosphere', can be observed directly. There are distinct regions to the solar atmosphere: the photosphere, the chromosphere, and the corona. These three regions have substantially different properties from each other, with regions of gradual transition between them

This website talks about the Suns X-rays and its its atmosphere. It even talks about some of the measurements of the sun and so much more information. There are additional links to click on within the website just in case you do not find what you are looking for.

It’s easy to read the information and everything seems right because I research other sites and they all pretty much say the same thing

Space Probes to the Sun

Summary about The Suns probes:


For more than half a century, astronomers have been trying to figure out how to get a solar probe to the sun. At last, we have the answer.
Justin Kasper, an astrophysicist in the at the Solar and Stellar X-Ray Group at the Harvard-Smithsonian Center for Astrophysics, is behind Solar Probe Plus, which will make the first ever trip to the sun—a NASAmission that will take begin in 2018. Kasper’s creation,SWEAP (Solar Wind Electrons Alphas and Protons) is one of the four instrument packages that will be on the spacecraft; it will help us learn why the sun is so hot and how the solar wind is accelerated to supersonic speeds.
Kasper is working with several institutions, including the University of California Berkeley Space Sciences Laboratory, NASA Marshall Space Flight Center, the University of Alabama Huntsville, NASA Goddard Space Flight Center, Los Alamos National Laboratory,University of New Hampshire and the Massachusetts Institute of Technology.
I recently talked with Kasper about the solar probe, why we want to get that close to the sun, and why the spacecraft won’t burst into flames.

This website talks about space probes that will be heading towards the sun within the next few years. The missions that will be going to the sun and gives dates that will let us know of the arrivals.

This website is pretty legit and credible it was made pretty easy to read and the information is on a legit website.

Think Quest

Summary about the Sun:


The Sun has spots on it called sunspots. A sunspot is a very large and violent storm with rain, thunder, and lightning. Most sunspots begin and fade in an 11-year cycle. Sunspots are cooler spots on the Sun. Sunspots always form in pairs. The reason for this is because sunspots are magnetic. One sunspot always has the north pull, and the other always has the south pull. Some sunspots last only a day, while others last as long as one month.
Sunspots have always confused astronomers. Some thought they were clouds, others thought they were mountains, and some thought they were a window to coolness. Astronomers today still do not understand everything about them.

This website is about the suns sunspots. It gives detailed information about how sunspots come about and the reason they called it sunspots. It even goes as far as talk about more information than just sunspots.

This page is made by students who probably just researched information about the sun. I cannot say if they are credible or not but the information seems legit. The information is very easy to read.

Sun Death

Summary about the Suns Death:


The Sun is about 4.5 billion years old. it has used up about half of its nuclear fuel (hydrogen). In about 5 billion years from now, the sun will begin to die.

As the Sun grows old, it will expand. As the core runs out of hydrogen and then helium, the core will contact and the outer layers will expand, cool, and become less bright. It will become a red giant star.

After this phase, the outer layers of the Sun will continue to expand. As this happens, the core will contract; the helium atoms in the core will fuse together, forming carbon atoms and releasing energy. The core will then be stable since the carbon atoms are not further compressible.

This website talks about the suns death and when it will possibly die or began to die. Pretty cool information and great insight might I say and I found the information pretty fun to read.

Additional Information (Facts about the Sun

The Sun is one among the 200 billion stars in our Milky Way galaxy.

The Sun is one among the 6000 stars, which is visible to naked eye from the Earth.

The mass of Sun is 2 trillion trillion trillion tons.

The Sun's energy output is 386 billion billion megawatt.

The Earth receives 94 billion megawatt of energy from Sun. This is equivalent to 40,000 times the power requirement of United states.

The reaction taking place in Sun is nuclear fusion, same as a Hydrogen bomb.

Each second 700 million tons of Hydrogen are converted to 695 million tons of Helium and 5 million tons of energy in the form of gamma rays.

Each second the Sun loses 5 million tons of material.

The Sun's temperature at its core is 14 million Kelvin.

The pressure at the Sun's core is 340 billion times the pressure at the Earth's atmosphere.

The density of matter at the Sun's core is about 150 times the density of water in the Earth.

It takes up to 50 million years for the energy produced at the core of the Sun to reach its surface.

If the Sun were to stop producing energy today, it would take 50 million years for significant effects to be felt at Earth.
