Exploring the chemical processes of the universe provides insight into planetary formation, interstellar matter, and the origins of life. Advances in spectroscopy and space missions reveal the complex chemistry of exoplanetary atmospheres, comets, and molecular clouds. Space & astrochemistry investigates the formation of organic molecules in extreme environments, shedding light on prebiotic chemistry and potential extraterrestrial life. Laboratory simulations and computational models help decode reactions occurring in deep space, from ion-molecule interactions to photochemical transformations. Understanding cosmic chemistry also informs space exploration, materials science, and planetary habitability. As technology advances, astrochemistry continues to expand knowledge of the universe’s molecular diversity and its connection to life’s origins.
