Making of Stars
Stars are made of enormous, cold and dense molecule skies, which can contain many tousand more matter than the sun, is exposed to changes on the outside. It may for example be a wave effect in a spiral galaxy or exploding stars.
Stars are huge gasballs which are billion times as heavy as Earth, and which lets out light by themselves.
The sun is a normal star. Some stars are bigger, and many stars are much smaller. Some are clearer, and some are weaker. Stars may have many diffrent sizes, temperatures and color.
The first making of a star began just shortly after The Big Bang. The intense heat that the earliest matter in the universe got from Big Bang itself, started to decrease, and became slowly gathered in big molecule skies. In these there occurred local changes, and because of the gasses own gravity fell the densest areas together into big, warm gas balls, which were many times bigger than out entire solar system. With the, the contraction brought with it so much matter that both temperature and pressure in the ever dense hoops of matter grew so much that the fusion reactions started to kick in. Exactly this phenomenon marks the birth of a star – now it can start to shine bright with its energy.
The first stars were born for about 100 million years after The Big Bang
