The Life And Death Of A Star

The Life and Death of a Star By: Christina Thiessen doorway: sightly like everything else in this world that snuff its and dies, every hotshot has its avouch spirit cycle too. There is a time that stars reach to go through just like humans. In this seek paper Im going to be telling you ab let out the life and death of a star. frame: A star is a hot, glowing ball of vaunt mostly made out of hydrogen. Stars give off wonderful light energy. There argon billions and billions of stars in the universe. Stars form in regions of space where there nuclear number 18 bulky accumulations of gas and dust called nebulae. Each nebula is composed of 75% hydrogen, 23% helium and 2% oxygen, nitrogen, carbon, and silicate dust. Depending on the different piling a star take offs from a particular nebula, the star leave alone either be Sun-like, or massive. The life cycles of massive stars atomic number 18 different from the life cycles of Sun-like stars al though they both live most of their lives in the main sequence. Although they are different, they both modernize energy by converting hydrogen into helium.All stars remain in this still state for millions and heretofore billions of years. Just like a car, the force out in a star eventually runs out. When the hydrogen in the vegetable marrow of the star has been used up, the star shrinks.

Then, the helium sum total starts to heat up so that it first starts fusing to the carbon, then to the different elements. As gloominess causes the star to extend, further nuclear chemical reactions develop. This leads to in volution of the outer layers. In this proces! s, the star becomes larger. If it a Sun-like star, it will wind into a ruddy-faced elephantine.If it is a massive star, it will turn into a passing supergiant. Our Sun will become a red giant in about 5 billion years. By that time, the Suns diam may extend past the orbit of Mars. The farthest whole tone in a stars life is when the concretion reaction stops. In a Sun-like star , the fusion ends when the temperature of the core is no semipermanent hot enough to keep the reaction going.
