Cosmologist believes that the uni verse was created 15 billion years ago with the expectant bang, which indeed released two of the most lightest elements known to man called heat content and Helium. When temperance pushes the two elements tightly, nuclear fission bequeath light to occur in the core of the principal. Stars are created in ogre clouds of dust and gas, but at times some of the clouds focus due to gravity. As it shrinks it becomes hotter and when its hot enough, nuclear reactions potbelly stove begin in the centre of the hint. Once nuclear confederation is producing heat in the centre of the new star, it will excrete off the star from collapsing for about 10 billion years, which will then lead to the end of its life. The balance between gravity act to make the star shrink and heat belongings it up is called Thermodynamic Equilibrium During its life of being a star, the appearances or colour of it wont change precise much. Stars arent alone the same thing; some of them have contrastive colour, size and brightness. The larger the star, the hotter and brighter it is which usually has a blue colour to it.
littler stars are less bright, collecteder and Red. Since they are so hot, the littler stars actually have a longer life than the bigger hotter ones, because they use a lot more elements then the subaltern ones. Eventually, the hydrogen in the centre of the star will stand out. No new heat will be do and the gravity will take over and the centre of the star will shrink. This will then make the star undisturbed down making the star look much big ger and redder, which will then create a Red! titan Star. For smaller stars they leave behind a nebula or a white dwarf.If you want to get a full essay, appetite it on our website:
