Astrochemistry is the study of the chemical processes and compounds that occur in space. It focuses on understanding how molecules form, interact, and evolve in various celestial environments, such as interstellar clouds, comets, and the atmospheres of planets. This field combines principles from both astronomy and chemistry to explore the origins of complex organic molecules and their role in the universe. Researchers in astrochemistry use telescopes and laboratory experiments to analyze the composition of cosmic materials. They investigate how these chemical reactions contribute to the formation of stars, planets, and even the building blocks of life, providing insights into the conditions that may lead to the emergence of life beyond Earth.
