This molecule was originally selected on May 24, 2004.

Regarding this week’s selected substance:

In Earth's ecosphere, coronene is considered a pollutant, but this polynuclear aromatic hydrocarbon redeems itself as an ultraviolet phosphor for charge-coupled devices (CCDs). Coronene-coated CCDs on the Hubble Space Telescope provide valuable information about molecules in outer space. Coronene has also been observed on the surface of Saturn's moon Titan.
