Cyanocoronene: Astronomers Detect Seven-Ring Polycyclic Aromatic Hydrocarbon in TMC-1
Cyanocoronene, composed of seven interconnected benzene rings and a cyano group, was found in the cold, dark molecular cloud TMC-1, a region known for its rich chemistry and as a cradle for new stars. Image credit: NSF / AUI / NSF / NRAO / P.Vosteen.

Astronomers using NSF’s Green Bank Telescope have detected cyanocoronene (C24H11CN) -- the largest PAH ever detected in space -- in the starless cloud core TMC-1, which is part of the interstellar Taurus Molecular Cloud.
