Astrochemistry sits at the intersection of astronomy and chemistry, studying molecules in interstellar clouds, circumstellar envelopes, and planetary atmospheres. In the near-vacuum of space, exotic reactions occur on dust grain surfaces and through gas-phase ion-molecule pathways that have no terrestrial analogue, producing complex organic molecules far from any living system.
These simulations let you explore the molecular universe. Model chemical networks in dense molecular clouds, identify molecules through their rotational spectral fingerprints, watch ice mantles grow on interstellar grains, probe photodissociation regions where UV light drives radical chemistry, and discover how isotope fractionation enriches cold clouds in deuterium — a tracer of our solar system's birth environment.
