About 5 billion years ago our milkiway fell underr the influence of an other galaxy. Through the reciprocal action between the both, fountains of gas shot from the centre of our milkiway, in to space. At the same time, gravitation forces, cause the forming of a "dark cloude" in shape of a "spiral arm". Gas, ice and star dust go together to molecule-clouds in it, which very often collapse, because of their own gravity. With this processe thousands of new stars were made, which put these regions in red light. Out of them, our sun slowly developed itselfe. |
