Nacreous Clouds over Iceland | Earth Science
Photographer Jónína Óskarsdóttir: "The day has been beautiful in Fáskrúðsfjörður, Iceland. Amazing light and beautiful nacreous clouds seen behind Mt. Jökultindur."
Vivid and lustrous, wafting iridescent waves of color wash across this skyscape. Known as nacreous clouds or mother-of-pearl clouds, they are rare. A type of polar stratospheric cloud, they form when unusually cold temperatures in the usually cloudless lower stratosphere form ice crystals. Still sunlit at altitudes of around 15 to 25 kilometers, the clouds can diffract sunlight even after sunset and just before the dawn.
