Stars form from clouds of gas and dust in space, known as nebulae. When regions within these clouds experience gravitational collapse, the material begins to clump together, increasing temperature and pressure. Once the core temperature reaches about 10 million degrees Celsius, nuclear fusion ignites, marking the birth of a new star. This process can take millions of years, resulting in various types of stars depending on their mass and composition.
