Life Cycle Of Stars

Running Head : LIFE CYCLE OF STARSLife Cycle of StarsByNameInstitutionINTRODUCTIONNothing in the universe stays the same forever , and stars argon no exception . However , we cannot see a star changing because it lives for billions and billions of historic period , emitting light and other electromagnetic waves equal receiving set waves , microwaves , and ultraviolet waves , together forming the electromagnetic spectrum . The colors of the rainbow form the exclusively part of this spectrum that we can seeThe All-important toolsAlthough all these waves go at the speed of light , each group of waves has a different wavelength and carries a different amount of energy . They litigate as the main clues in determining the stages or the conditions of the stars and olibanum our main tool to understand and calculate the past , prove and future of the universeOh be a fine girl , osculation meClassified by their spectra (elements they absorb ) and temperature stars belong to seven main qualitys , consecutive go to sleepn as O , B , A , F , G K , and M . Thus came out the mnemotechnical for remembering these is Oh Be A Fine Girl , snog MeThen thither is the Hertzsprung -Russell (H-R ) Diagram a graph that plots stars color (apparitional type or surface temperature ) vs . its luminosity (intrinsic brightness or impregnable magnitude . On it astronomers plot stars color , temperature , luminosity , spectral type and evolutionary stage . This diagram shows that there are 3 very different types of stars , and these are Main Sequence Stars Supergiants and unclouded Dwarfs (Neutron stars , or Black HolesPower StructureAccording to the scientists , 15000 million years ago the Universe was natural in a colossal explosion called the Big sweetheart , which created all matter , energy , space , and time . at heart minutes of the explosion , nuclear particles came together to make the gases helium and hydrogen , which over millions of years produced the galaxies , the stars and the Universe as we know it today .

That was the beginning of a process of expansion and potpourri , which still continues todayThus the timeline goes like this : 1000 million years afterward the Big Bang material started to come together , 3000 years after , galaxies started to take shape , any(prenominal) later quasars , the forerunners of galaxies , evolves past around 5000 million years after , our galaxy , the whitish Way , one of 100 ,000 million galaxies , formed into a disc shape . The celestial hierarchy thus goes like this : Big Bang Nebulae Protostar T .Tauri type star save consolidation Main Sequence star increase in luminosity Red Giant star Cepheid Star White /Black Dwarf /Black HoleThe Big Bang system is still accepted as valid , though some questions still remain answered- hierarchy of stars , galaxies , and clusters of galaxies formed from the fiery junk of that initial spark . However the cosmologists are relentlessly running(a) on to get a the greater picture that was there out of what we see todayCharacteristicsGiant nuclear reactorsIn the center of stars , fantastic atomic collisions rip apart the atoms and alter their structure , thereby relinquish an enormous...If you want to get a full essay, order it on our website: Orderessay
