The Sun
The biggest and most vital star to our solar system
The sun
This is the biggest star in our solar system. It is very important because it provides our earth with the energy we need and we could not live without it!
Core
The core is the most important part of the sun. The core is made up of tons of different gases because of nuclear fusion, but the two main gases are hydrogen and helium.It provides it with necessary energies to create nuclear fusion that powers the sun. All the heat from the sun is created in the core. Its temperature is a blazing 27 million degrees Fahrenheit!
Radiative zone
The Radiative Zone lies right outside of the suns core. The radiative zone is made up of the energy and gases that is exerted by the sun's core. It radiates energy for the sun through a complex process called photon emission. Even thought the core is the hottest part of the sun, The radiative zones temperature is still a whopping 10,000 degrees Fahrenheit.
Convective zone
The convective zone is the outermost layer of the sun. It is composed entirely out of plasma and has some gases in there too. Since this zone is not hard or dense enough, it cannot use radiative transfer. It alternative is using thermal convection zones. It creates areas of solar granulation and small magnetic fields. Since the heat is transferred through a different process, the energy warms and the regular temperature of this zone is a sweltering 3.5 million degrees!
suns photosphere
The suns photosphere is the part of the sun that is visible to us. It is made up of plasma and many gases. It is 100 kilometers thick, which is very thin for the sun. You can see dark granules and sunspots on the photosphere. the regular temperature of the photosphere is a boiling 5,730 degrees Celsius!
suns chromosphere
The chromosphere is the irregular layer above the photosphere. When the photosphere reaches higher temperatures, it emits a light that is a reddish color which illuminates the chromosphere. That's how the chromosphere got its name. The chromosphere is so thin and weak that it can really only be seen during eclipses.
solar flare
A solar flare occurs when the magnetic energy in the solar atmosphere has built up so much over a period of time, is released. This cause radiation to spread across the electromagnetic spectrum.
Suns prominence
The suns prominence is also known as a solar disk. Is a feature or part that extends outward from the suns surface. It extends so far that is goes into the suns hotter atmosphere or also known as corona. A prominence forms over a time span of about a day. It is made out of plasma
Suns spots
Sunspots are located on the suns photosphere. They appear as darker brownish spots on the sun. They appear because of concentrations of magnetic field flux that inhibit convection in the sun. They usually come in pairs and forms over a time span of a couple days to a couple months. they eventually weary away.
suns corona
the suns corona is the layer of plasma that surrounds the sun. It millions of kilometers long and extends way out into space. The suns corona is very thin, so it is most visible during a solar eclipse. It can be observed with cornograph also. It regular temperature is about 1 million degrees Fahrenheit!
aurora
An aurora is also known as the northern lights. It forms when when gases and particles or released during a solar flare and they penetrate earths magnetic shield of the atmosphere. they collide with many other atoms and molecules. the overall collision causes many bursts and explosions of light (also known as photons). This is what makes up an aurora
