Life and death of the Sun

The nearest star to our planet is Sol who is Latin for the Sun. For billions of years, the Sun was there to give us, life, light and heat. Although the Sun has given us life, but we can feel really confident, because we can kill at any time without much attention. Although we gave life, which was still viewed as a mysterious object.


The Sun and all the universe once were thought to revolve around the Earth, but we discovered that the Earth and other planets orbit around the Sun and there is no center of the universe.


The Sun has seven layers of that light takes a journey to another. First nuclear fusion occurs when atoms of hydrogen ram into each other with such force that they produce in helium atoms, that is what makes the particle of light. The radiation zone is the next layer that once they are created. This comes as electromagnetic radiation; However, it will take them millions of years to get out of this level. After the fight with the area of radiation entering the convective zone, and now must escape in addition. A lava lamp is best to compare the convection zone because both get on heat. Then came the photosphere, which is the place that send to the planets. Ended the journey through the Sun and the light reached the planets. The solar atmosphere has layers, just like the plasma surface.


The chromosphere is visible during a solar eclipse, like the color on the edge of eclipse. The Crown is in control of the solar wind and Heliosphere. The Heliosphere is the amount of magnetic control the Sun.


Sun will one day and this is how it can go, Sun will magnify insufficient to absorb mercury and Venus, the Earth may be able to move away from engulfment, at that time the Earth will be a barren place anyway. How science teaching you said, for every action, there is an equal and opposite reaction. The action was the Sun, giving life to the land and the equal and opposite reaction is ending the Sun life.


The solar system is very large but approximately 99.8% of the mass of the solar system is the Sun. Everything that orbit around the Sun, and is responsible for life found on Earth. Sol is composed of hydrogen and helium, hydrogen is the 74% of the Sun in mass and helium is 25% of the Sun's mass. Hydrogen is the 92% of the volume of the Sun; Therefore, helium is only 7% of the volume of the Sun. The Sun uses a process called nuclear fusion of light and heat do, and how it is done is by hydrogens to knock into each other at such speed that they become helium atom and left out energy called a pharos who take millions of years to reach the surface of the Sun, but take only about ten days to arrive to the planets.


For 4.5 billion years the Sun was there to give us the light and warmth and life as well, but is about half way through the supply of fuel. More than 4,000,000 tons of matter is converted into energy within the core of the Sun. The Sun is a main sequence star, and will continue to be for 10 billion years, when the Sun runs out of fuel. A yellow dwarf star is the astronomical term for the type of star is the Sun, it also says that those stars do not have sufficient mass to go super nova. 4 or 5 billion years the Sun will enter the red giant phase, its outer layers will expand as the hydrogen fuel in the core contracts and heats up. After the red giant phase throws off its outer layers and leaving the core to cool slowly until it fades into a white dwarf star, which is the most powerful of the universe, and it will take billions of years for that to happen.
