An artist's impression of the newly identified, largest polycyclic aromatic hydrocarbon detected to date, cyanocoronene. This molecule, composed of seven interconnected benzene rings and a cyano group (C₂₄H₁₁CN), was found in the cold, dark molecular cloud TMC-1, a region known for its rich chemistry and as a cradle for new stars.
