How the stars are born and how you die

Every night we look at  the sky so thick, the scenery is beautiful and beautiful, but have we  ever thought of how these stars formed? Does she have a certain age or does she remain? And how do you die? 

 How stars form
The result of the large explosion was the hydrogen and helium atoms,  since these two elements have characteristics that distinguish them from  other elements, which made it the property of building stars
These atoms began to approach each other, and began to combine with  each other; which led to the formation of what is known as sand, a dusty  clouds
These clouds began to attract the atoms around them, about 300  million years ago, which led to the condensation of these clouds and  increasing their temperature.
The massive rise in temperature in the nebula caused the center to rise dramatically, leading to a massive nuclear explosion.
After the explosion, the hydrogen atoms were assembled together, with a large amount and high temperatures.
The nebula turned into burning, high-temperature balls, which led to the formation of the so-called stars

 How the stars die
The stars remain burning and lit up until the amount of material in  them is carried out. Each star has a quantity of matter inside it that  keeps it burning.
A star that contains a larger amount of matter dies faster, that is,  the relationship is inverse. The larger the size of the material, the  faster the star's chance of death, or the shorter the star,
The  sun, which is the nearest star to us, and the largest star around us,  needs four billion years for the matter to be carried out and die, where  the atmosphere of the sun will be in a state of expansion and collapse;  which will lead to the sun swallowing nearby planets such as Mercury And Venus, while the planet will evaporate from the heat. There are stars a few times larger than the sun, these stars are  trying to drain their helium quickly, and when all the amount of helium  contained in these stars, a huge explosion will shake the galaxy 

 The birth and  death of stars are a daily occurrence, but we do not feel it. The reason  is that these stars are about us, and these stars may not be so large  that we notice their disappearance. There is another reason: the huge  number of stars in the galaxy, Which will make us  unaware of the number of stars that existed yesterday and the rest of  them today, to calculate how many stars died today
