Rare and Stunning 'Rainbow Clouds' Illuminate Northern Skies in Spectacular Display
Spectacular "rainbow clouds," also known as nacreous or polar stratospheric clouds, have been spotted in the skies of northern regions. These high-altitude clouds, which form between 13 and 19 miles above Earth's surface, are illuminated by sunlight from below the horizon, creating a stunning rainbow effect. While they provide a mesmerizing display, nacreous clouds also contribute to ozone depletion in the Arctic.
