Nebulae are vast, luminous clouds of dust and gas in space, often illuminated by the stars within and around them. They are not merely astronomical objects; they serve as laboratories for understanding the life cycle of stars, the formation of planets, and the chemical composition of galaxies. Nebulae are a critical component of cosmochemistry, the study of the chemical composition and evolution of the universe, as they provide insights into the elements that form the building blocks of matter. They are also an essential part of astronomy, allowing scientists to study the physical processes that govern the behavior of gases and plasmas under extreme conditions. In this context, nebulae fit seamlessly into the broader categories of science, astronomy, and cosmochemistry, providing a bridge between these disciplines and offering a unique perspective on the universe's mysteries.
