Can We Make A Star? By:Mike Alcazar Outline • • • • • What Is A Star? Our Star Did You Know? Why Would We Need To Make A Star? What Do We Need To Make A Star? What Is A Star? • They are made of cosmic dust, mostly hydrogen and helium • They are very unstable • The are very violent • They give off an extremely large amount of energy Our Star • The Sun is what makes life possible on Earth • The Sun is powered by nuclear fusion in the core • The Sun is the closest star to the Earth • If it was any closer or farther we would not be alive Did You Know? • • • • • The Sun’s diameter is 1,390,000 km The temperature is 5800 k on the surface The temperature is 15,600,000 k in the core It is 70% hydrogen and 28% helium Eventually the Sun will become a white dwarf Why Would We Need To Make A Star? • We might need to make a star so that in the future life may continue to progress on Earth • Just in case our Sun immediately burns out • And just so we could be cool like Star Wars What Do We Need To Make A Star? • Fist we need to get a hold of a lot of helium and hydrogen • Then we need to get the mass of gas to move so that the gasses will react with each other • Then we just sit way back and wait until the gasses explode into a fireball Who Would Make It? • Scientists in many different parts of the world are trying to learn everything they can about stars • They may build a team of scientists who have been studying stars for their entire career • This would take years of training even for them Summary • I think that in the future, near or far, we will need to know how to make a star. This could keep the human race and everything else on Earth alive.
