Details
Coronene is a flat carbon-rich molecule built from seven fused benzene rings. It is often used as a stand-in for the PAH family, whose infrared signatures are thought to be widespread across interstellar clouds and other dusty astrophysical environments.
Coronene serves astrochemistry mainly as a laboratory and computational reference; it has not been individually identified in interstellar infrared spectra. Researchers compare its vibrational modes with the broad infrared bands attributed to mixtures of polycyclic aromatic hydrocarbons. The match constrains a molecular family while leaving the individual carriers uncertain.

About
Scale of Space is a scroll-based journey through the universe, placing objects on a single logarithmic scale so you can compare size across an unbroken range.
Guides explain selected parts of that range, while focused views filter the objects by subject.
