Rings around LunaKnown as coronae, these shiny iridescent rings are due to the diffraction of light around water droplets of similar sizes in the thin veil of wispy cloud in the atmosphere, though dust and aerosols such as pollen can also produce the effect. While they also occur around the sun, seeing them is uncommon, as the intense glare usually drowns them out, rendering them invisible. It is a quantum effect, with each light ray being bent around one droplet, and the different wavelengths in the white reflected solar light being diffracted in varying amounts due to their inherent energy levels. This example was snapped in Argentina.LozImage credit: Sergio Montúfarhttps://www.facebook.com/MilkyWayAddictedhttp://bit.ly/1cWrj8thttps://apod.nasa.gov/apod/ap150615.html -- source link
