OriginalFraunhofer lines, absorption dips in the sun's spectral radiation
Reason
Quality image shows the physical phenomenon Fraunhofer lines, which are the absorption dips in the optical spectrum of the sun. The dips are caused by the absorption of sun's radiated energy by atoms in the sun's atmosphere. This phenomenon was first observed in 1814. The nominated image is a recent quality measurement and dates to 2022. The image is not in the infobox, but it is properly placed next to a corresponding table which lists the dips, their wavelengths and the corresponding atoms.
