    nuclei fuse to form helium nuclei is the source of solar energy of the sun. In this process‚ enormous amount of energy is released. REACTIONS IN THE SUN There are two different cycles of processes. One is the proton-proton chain or p-p chain. The other is the Carbon Cycle or CNO cycle (Carbon-Nitrogen-Oxygen) or sometimes Bethe- Weizsäcker-cycle. Proton-Proton chain: The proton–proton chain reaction is one of the fusion reactions in which four Hydrogen nuclei fuse into one Helium nucleus with the

    star‚ and that’s true because there are many others similar to it but there are smaller stars than larger ones; The Sun is on the top 10% by mass. The Sun is about 70% hydrogen and about 20% helium. Everything else like metals is about less than 2%. This changes as the Sun turns hydrogen into helium in its core. The radius of the giant star is 432‚288 miles‚ while the mass is 1.982 x 1030 kilograms. Atmosphere

    Solar disruption theory was one of several theories that emerged before the 18th century concerning the formation of the solar system. Solar disruption theory states that the collision of the sun with another stars caused debris to be ejected from its mass and these debris eventually became the planets. This theory was later discarded for the nebula theory of solar system formation. However there are some scientists that propose that it has some merit. The big question up until the 18th century

    Transuranic Elements and their Production Transuranic elements are elements that have an atomic number greater than 92. Transuranic elements have been synthesised in nuclear reactors or in high-energy particle accelerators. Neptunium and plutonium were the first transuranic elements to be synthesised in 1940 by Glenn Seaborg’s research team in the USA. Uranium 238 is bombarded with neutrons produced by the nuclear fission of U-235. Initially an isotope of uranium (U-239) forms which decays

    atomic velocities not to be able to escape the system’s gravity‚ so star formation only occurs in a few areas. The sites of star formation in the galaxy are mostly located within molecular clouds – expansive‚ cool clouds of mostly hydrogen and helium gas. Molecular clouds are on average too diffuse to contract gravitationally‚ but within a cloud are regions of locally higher density‚ which are the sites of active star formation. It is not known exactly what causes molecular clouds and star-forming
