Interstellar molecules as a research area focuses on the detection, identification, and characterization of molecules in the interstellar medium (ISM), and on understanding their formation pathways, destruction processes, and astrochemical evolution. It integrates radio, millimeter, infrared, and UV spectroscopy with theoretical chemistry and reaction-kinetics modeling to constrain physical conditions in molecular clouds, diffuse clouds, and circumstellar envelopes. Research addresses gas-phase and grain-surface chemistry, isotopic fractionation, and the role of UV radiation, cosmic rays, and shocks in driving molecular complexity. This field informs models of star and planet formation, the chemical enrichment of galaxies, and the potential prebiotic inventory delivered to nascent planetary systems.
Clues about how galaxies like our Milky Way form and evolve and why their stars show surprising chemical patterns have been revealed by a new study.
