Nebulae are areas in space where clouds of dust, gas, and plasma can come together to form stars and other celestial objects. These regions are often characterized by their immense size and low density, allowing gravity to gradually pull the particles closer together over long periods of time. As the material condenses and becomes more concentrated, it can eventually reach the point where nuclear fusion ignites and a star is born. Nebulae can also serve as the birthplaces for planets, moons, and other smaller bodies within galaxies.
