The Life And Death Of A Star

The Life and Death of a Star By: Christina Thiessen origination: sightly like everything else in this world that proceeds and dies, every brain has its avouch spirit cycle too. There is a succession 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. eubstance: A star is a hot, glowing ball of fellate mostly made out of hydrogen. Stars give off dread(a) light energy. There argon billions and billions of stars in the universe. Stars form in regions of space where there atomic number 18 long 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 final result either be Sun-like, or massive. The life cycles of massive stars atomic number 18 different from the life cycles of Sun-l ike stars although they both live most of their lives in the main sequence. Although they are different, they both m another(prenominal) energy by converting hydrogen into helium.All stars remain in this static state for millions and heretofore billions of years. Just like a car, the burn down in a star eventually runs out. When the hydrogen in the philia of the star has been used up, the star shrinks.

Then, the helium issue starts to heat up so that it first starts fusing to the carbon, then to the other elements. As gloominess causes the star to extend, further nuclear answers develop. This leads to amplification of the outer lay ers. In this process, the star becomes large! r. If it a Sun-like star, it will wring into a ruddy-faced elephantine.If it is a massive star, it will turn into a bolshie 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 stick up whole tone in a stars life is when the league 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.
