Cosmochemistry is the study of the chemistry of the universe, specifically focusing on the composition, structure, and processes of celestial bodies such as planets, moons, asteroids, and comets. This field explores the formation and evolution of these objects, as well as the distribution and abundance of elements and molecules in space. Cosmochemists analyze samples from meteorites, rocks brought back from space missions, and observations of distant objects to understand the chemical and physical properties of celestial bodies. By studying cosmochemistry, researchers seek to gain insights into the origin and development of the universe and our solar system.
