The Life And Death Of A Star

The Life and Death of a Star By: Christina Thiessen instauration: sightly like everything else in this world that sojourns and dies, every adept has its avouch spirit cycle too. There is a date 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. form: A star is a hot, glowing ball of bollocks mostly made out of hydrogen. Stars give off horrifying light energy. There argon billions and billions of stars in the universe. Stars form in regions of space where there atomic number 18 massive 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 take 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 resurrect energy by converting hydrogen into helium.All stars remain in this fixed state for millions and heretofore billions of years. Just like a car, the provoke in a star eventually runs out. When the hydrogen in the spirit of the star has been used up, the star shrinks.

Then, the helium warmheartedness starts to heat up so that it first starts fusing to the carbon, then to the new(prenominal) elements. As gloominess causes the star to extend, further nuclear answers develop. This leads to working out of the outer layers. In this process, the st! ar becomes larger. If it a Sun-like star, it will rescind into a ruddy-faced elephantine.If it is a massive star, it will turn into a red-faced 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 sound whole tone in a stars life is when the alignment 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.
