How Are Stars Born? The Amazing Star Formation Process

Ever wonder in space how are stars born? It's surrounded by massive clouds of cold gas and dust. A cloudy and gloomy day. The key player here is gravity. Gathers up the gas and dust. The centre becomes hotter and hotter as they form into clusters. When the temperature hits about 10 million degrees, a nuclear reaction ignites. That reaction gives off energy. That energy is light. That is the light that we see when we look at a star. The entire process will take millions of years. But the result is a shining star that can live for billions of years. The Birthplace: Molecular Clouds Stars form in places called molecular clouds. These are huge areas in space full of gas and dust. They are very cold. The temperature can be as low as -440°F . Most of this gas is hydrogen. About 28% is helium. The rest is tiny amounts of other elements . These clouds are often called stellar nurseries. This is because they are
