Stellar Nucleosynthesis

Throughout generations stories were passed down about how things could've been created like the earth, mankind, and even the stars. Every culture and religion has their own myth of how things came to be. The Hindu’s, Native American’s, and the Chinese all made up stories about how the stars were created.

According to Carolyn Ruth, author of “Where Do Chemical Elements Come From,” chemical elements came from the explosion of stars, also known as supernovas. In her article, Carolyn states that a newborn star is mainly composed of the first element on the periodic table, Hydrogen. Due to the high pressure within the star, a fusion process begins that fuses two protons and two neutrons together to form the second element, Helium. These fusion processes continue to form elements that weigh less than Iron. Once the star creates all elements up to Iron, the star eventually collapses and explodes. One article that agrees with Carolyn’s theory is “The Origin of the Elements and the Life of A Star”. According to this article, stars produce nuclear reactions

form organic molecules that create the basis for life. The main elements found in biological

The sun is a star that is made up of hydrogen gas. The sun is unlike other stars that we see in the sky because the sun delivers energy and radiation that allows to living things to exist. Also, the sun is much closer than the other stars in the sky.

[25] Which of the following does not play a role in creating the elements needed for life as we know it?

Carbon Atoms are very important in building biological molecules. Carbon has many characteristics that make possible building of a variety of carbon-based biological molecules. Carbon has four valence molecules, is very abundant, and carbon creates very strong covalent bonds. Carbon's four valence electrons allows the molecules to create four different covalent bonds, and it makes it much easier to bond to other molecules. The balanced electrons makes it easy to break bonds and form them, therefore building biological molecules. Carbon is in the top five most abundant elements in the universe, which makes it very important or there wouldn't be so much of it. The amount of carbon creates a variety of carbon-based biological molecules because

Their results stated that a large majority of the universe then was made up of hydrogen, the simplest element known to man with the atomic number of 1. This is a result of the first subatomic particles bonding together in a stable way. Eventually Helium was formed with the atomic number of 2; the second simplest element. Those same scientists found that around 27% percent of all matter in the universe was Helium. Today, the composition of all matter in our universe is staggeringly around 75% Hydrogen and 27% Helium, nearly the same as what the predicted. The Big Bang theory states that the simplest elements were made first(being hydrogen and Helium) and continues today, similarly to 13.7 billion years

Remember the phrase “We are all star stuff”, we’ll it’s true. The matter and elements our bodies contain were made from a detonating star, which has additionally given us distinctive numbers planets and different stars. The blast of a star is known as a supernova (supernovae for plural employments). Supernovas are extremely intriguing, brilliant, and vital, for a hefty portion of reasons, however to start with, you'll need to comprehend what a supernova is.

“First, in order to put everything in perspective, we must return to the dawn of our universe. In the beginning, nearly fourteen billion years ago, the Big Bang created time and space from a single infinitesimally small point that exploded and released tremendous energy causing the universe to expand as it still is today. Specifically, the energy was in the form of electrons, protons, and neutrons. Protons and neutrons later clumped together to form the nucleus around which electrons orbited to produce the very first atoms, such as hydrogen. In other words, atoms make up the building blocks of all matter. The electrons, protons, and neutrons are the subatomic particles. Hydrogen, the lightest atom, has one proton in its nucleus around which an electron orbits. Clouds of hydrogen atoms formed the primordial nebulae. When the nebulae became thick enough, the hydrogen atoms clumped together, amassing gravity and even more hydrogen atoms to eventually form the core of the stars. After two hydrogen nuclei collided and fused at the high temperatures in the core, the element helium formed in a process called nuclear fusion. Nuclear fusion releases tremendous energy that makes stars give off light and heat. Our Sun shines chiefly due to nuclear fusion. In fact, stars first

Those stars in the night sky seem small and tiny, but up close they would be millions of times larger than the Earth. Stars are the most recognized astronomical objects and are the building blocks of the galaxies. These luminous spheres made of plasma are responsible for the creation of heavy elements like carbon, nitrogen, and oxygen. They were among the first objects in the early universe. Most of the elements found in the human body originated in stars, this means that we are literally made of stardust. When you are staring at stars from the night sky, you are actually looking back in time, the light you see could be from a million years ago. The study of the birth, life and death of stars are the central field of astronomy today.

During the creation of stars, denser nuclei were generated from hydrogen and helium through the continuous procedure of stellar nucleosynthesis. Stars make fresh elements in their nuclei by enfolding elements together in a procedure known as nuclear fusion. Stars join hydrogen atoms to helium, then the Helium atoms are fused to generate beryllium, this process goes on, till blend in the core of star has generated each component up to iron. Nuclear fusion occurs in the hydrogen gas in the center of the Sun. It becomes squeezed together so firmly and four hydrogen nuclei join to develop one helium molecule. In the procedure, a number of-of the mass of the hydrogen atoms gets changed to energy in the formula of light. The similar procedure

It is common scientific knowledge our Sun is a star. What makes our big glowing ball of plasma a star? It’s because the high-powered synthesis of hydrogen into helium in its core that makes our star shine the brightest in the Milky Way. But just 100 years ago, we knew so littler about our Sun, scientists didn’t even know it’s true composition. It wasn’t until the great works provided by Cecilia Payne-Gaposchkin, who discovered that the composition of our Sun was the abundance of hydrogen. This helped prove hydrogen as the most abundant element in the Universe and of course changed how we looked at our Sun today. Cecilia is role model for all women to look up to especially in Astronomy.

The composition of other stars is very similar to our own Sun. They are made up of mostly hydrogen and helium and tiny traces of heavy elements.

4.Main sequence stars fuse hydrogen atoms to form helium atoms in their cores. About 90 percent of the stars in the universe,

As described in our text, the material that makes up the universe is recycled constantly through the formation and evolution of stars. Clouds of atomic gas cool and condense, forming cold, dense clouds of molecular gas. Within these clouds of cold gas, stars can form. It takes just some push, pull, or magnetic field to cause the cloud to fall into gravitational collapse. Once the cloud is collapsing, the road to becoming a star is an inevitable one. The formation of a star involves many different stages. In the beginning, there is just dust and a gas. Slowly, over time, the dust and gas form a cloud of material containing all the right ingredients for star formation. Then, the cloud to gravitationally are caused to collapse. The cause can be
