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
