Cyanocoronene: Astronomers Detect Seven-Ring Polycyclic Aromatic Hydrocarbon in TMC-1
Polycyclic aromatic hydrocarbons (PAHs) are expected to be the most abundant class of organic molecules in space, yet their their lifecycle in the interstellar medium remains poorly understood. Now, astronomers using NSF’s Green Bank Telescope have detected cyanocoronene (C24H11CN) — the largest PAH ever detected in space — in the…
