stars formation

Stars form in vast clouds of gas and dust called nebulae. When parts of these clouds gather enough material through gravity, they clump together, creating a dense core. As more gas spirals in, the core heats up. Once it becomes hot and dense enough, nuclear fusion begins, converting hydrogen into helium and releasing energy. This process lights up the star and halts further collapse, allowing it to shine steadily. Over millions to billions of years, stars remain in this state, eventually evolving or ending in dramatic ways depending on their size.
