The process of dying stars will occur after several billion years of life begins. How and what is the process like?
Both the life and death of stars make up the chemical elements that make up the earth. When viewed as if the stars are like permanent objects in the night sky. But in the end the star will die.

Stars start their lives because of the fusion of hydrogen ignited in their dense and hot cores. The early universe contained nothing but the chemical element hydrogen, small amounts of lithium and beryllium as well as helium.
So during their life cycle, stars create elements with low atomic mass. Once the process begins, life begins.
The Beginning Of The Dead Star Process To Disappear
Before stars and planets existed, giant clouds of hydrogen and helium formed. Slowly these clouds collect mass to form their gravity. This creates a dense ball of gas called a star.
When it forms, it is hit by a strong and large enough gravitational force, so the star is dangerous to collapse. While nuclear fusion provides energy for the star, it pushes back the collapsing core.
Nuclear fusion releases energy. At the core of a newly formed star, the hydrogen nucleus melts into helium. The effect is the gravitational pull and the push of nuclear fusion outward and balanced. Nuclear fusion prevents shooting stars, it can also create new elements that have never existed before.
Depending on size, stars make elements by fusion to iron. Stars live for a very long time before they finally die, because they are so small they don’t need a lot of energy to balance gravity.

The atmospheres of the stars are constantly circulating, attracting fresh hydrogen and fueling continuous fires. Red dwarfs burn hydrogen for trillions of years.
When the nucleus runs out of hydrogen fuel it will contract under the weight of its gravity. Some hydrogen fusion occurs in the top layer and expands.
While the outer layer expanded, the star finger increased and became a red giant. The sun’s radius will be just outside the Earth’s orbit. The nucleus will heat up to cause the helium to melt into carbon.
When the helium is depleted, the nucleus expands and cools. The top layer expands and ejects material that will collect around a dying star and form a planetary nebula. The core will cool to become a white Dwarf and become a black Dwarf. The process took place several billion years
The Final Stage of Star Death
The largest star becomes a blue supergiant before the star eventually dies. They created a huge explosion in the universe as they began to collapse. So there was a big explosion called a Supernova.
The initial explosion of this supernova has so much energy and is capable of splitting the atom in its core. In addition, it is capable of sending Protons and Neutrons flying into the universe.
The moment after the explosion, the particles hit each other with enough energy to coalesce. From light elements it still keeps colliding with Neutrons and Protons continuously until it grows bigger and bigger.

This process is nucleosynthesis. The process occurs during the explosion Supernova produce an element with an atomic number higher than iron. However, nuclear fusion cannot be made.
When a star dies, new elements including gold are formed and those elements end up on earth. After a supernova explodes, the remaining core is massive and has a very strong gravitational pull. Even the light can’t go away. This is called a stellar black hole.
How a star dies, then its life cycle can change universe. Without stars, the universe would only contain clouds of hydrogen and helium.
It is the life and death of the star that is responsible for the elements that make up all that can be seen from the earth.
Shock waves from supernovae can initiate star formation in interstellar clouds. The remnants of the core can form a neutron star or a black hole depending on the mass of the original star.
The process of dying stars occurs in each star depending on the type and size. But this happened after billions of years of life. (R10 / HR-Online / Editor-Ndu)
