For decades, astronomers have watched sulfur vanish — abundant in the thin clouds between stars, yet nearly absent in the cold, dense nurseries where new stars are born. A team at the Max Planck Institute for Extraterrestrial Physics and Spain's Centro de Astrobiologia has now built a computational model suggesting that this missing sulfur hides within icy dust grains, locked in chemical forms that telescopes cannot easily see. Their work, built around a simulation called pyRate, reveals that at temperatures near absolute zero, chemistry does not wait for molecules to wander — atoms react the
