Inside stars, the main process going on is nuclear fusion, and helium nuclei can indeed fuse with other things to make heavier nuclei. All matter that makes up the Earth, along with the stuff that we are made of – Carbon, Nitrogen, Oxygen, was forged in the cores of high mass stars that burned and died long before the Sun. Sun is a star and all stars are big balls of gas, primarily made up of gargantuan amounts of Hydrogen and Helium.

Since the probability of tunneling through Coulomb barriers is very low, fusion processes in low mass, relatively cooler stars like Sun, occur very slowly. It is mandatory to procure user consent prior to running these cookies on your website. In the weird, sub-microsopic world of quantum mechanics, there is always a finite probability that the protons will fuse together at an energy that will be, lower than required energy to climb the Coulomb repulsion hill. For the past 4.57 billion years, since its birth, the Sun has been steadily fusing Hydrogen into Helium (a stage known as the Main Sequence in stellar physics parlance) and it will continue to do so for the next 5.43 billion years. At temperatures between 14 million to 23 million Kelvin, the ppII branch is dominant. Join Yahoo Answers and get 100 points today. The Sun is stable due to the hydrostatic equilibrium achieved between the self-gravity of the Sun and the thermal pressure generated by fusion in the core.

About 75% of the Sun is made up of Hydrogen, while the rest is mostly all Helium. Further, the diproton undergoes beta decay (proton gets converted into a neutron, along with the release of an electron neutrino and a positron, which is the antiparticle of the electron) to get converted into deuterium, along with the release of a positron and an electron neutrino. Sun – The Ultimate Nuclear Fusion Reactor. Imagine an adamant old man, trying to scale a wall. The energy released through gamma rays and the kinetic energy of the particles contributes to generation of thermal pressure in the solar interior, effectively balancing it with the gravitational pressure to maintain an overall steady state. Jupiter is not massive enough to create the conditions in its core that would result in sustained fusion of hydrogen. On its way, the gamma ray photons emitted in the fusion reactions are converted into visible light, infrared and ultraviolet photons, as they reach the photosphere. Solar interior witnesses a constant tussle between the crushing gravitational force and thermal pressure, generated by nuclear fusion in the core.

Its nucleus is just a proton. Solar energy sustains all the life on our planet through photosynthesis, and sets the rhythm of our climate and seasons. Here are the steps: Theorized, but not yet observed, this Helium-Proton fusion pathway is extremely rare. This small introduction is for those, who are not familiar with atomic physics.

Later on our sun will take the helium and fuse it together to make.

There are 92 different types of naturally occurring atoms. Like p-p chain reaction, the CNO cycle has several alternative paths, but the dominant one, occurring in the Sun, is primarily CNO-I. In the United states the seven brightest stars within ursa minor are commonly referred to as the? You can sign in to vote the answer. Hydrogen in the Sun is not burning.

Get your answers by asking now. How far the fusion continues depends on the mass of the star. The end products of both the processes are same. Which is more accurate: astrology or numerology? However, despite occurring at higher temperature, overall energy released through the whole reaction is again 26.73 MeV, which is round about the same as p-p cycle. This process produces only 0.8% of the Sun’s total energy output. How many times will the earth orbit around the sun? A type of an atom is decided by the number of protons in it. The heart of the Sun has a temperature close to 15.7 million Kelvin.

In a later stage of its evolution, it will fuse the helium into heavier elements, but that's not happening now. The Hydrogen and Helium atoms that constitute Sun, combine in a heavy amount every second to generate a stable and a nearly inexhaustible source of energy.

Why doesnt the sun presently create energy by fusing helium into heavier from AST 101 at Minnesota State University, Mankato The nucleus consists of two types of particles – protons and neutrons. When there is enough helium in the Sun's core to make it hot and dense enough, the Sun will start fusing helium into carbon. These cookies will be stored in your browser only with your consent. The total energy produced by the fusion of 4 protons through these processes is 26.73 MeV.

Next time you see a sunrise, you will be able to appreciate the beauty of the glowing hot ball of fire, even more, as you now know what goes on in its very heart.

Would you like to write for us? Nuclear fission is a chain reaction because the splitting of heavier elements releases neutrons that collide with other atoms and cause them to split. If you wished to maximize the products of the following reactions, which concentrations would you lower or raise?

Find answers now! Or does the Helium go through another process?

This process also fuses four protons into a Helium nucleus, by using Carbon (C), Nitrogen (N) and Oxygen (O) nuclei as catalysts.
