Atmospheric Glowing

Mysteries of some atmospheric glowing halos remain unexplained after 5,000 years

(ORDO NEWS) — The origin of some atmospheric optical phenomena remains unclear even after thousands of years of observations. For the first time in nearly 5,000 years of observations, researchers have compiled a complete catalog of optical phenomena created in the sky by light passing through ice crystals called atmospheric halos. The “inventory” of atmospheric halos details frequently occurring atmospheric optical halos from known sources, and shows rarer halos, including…
