Glowing clouds are a fascinating atmospheric phenomenon that occurs when certain types of clouds reflect or scatter sunlight in a way that makes them appear illuminated. This effect is often seen during sunrise or sunset when the sun is low on the horizon, casting warm colors onto the clouds. Another type of glowing cloud is known as noctilucent clouds, which are high-altitude clouds that can shine brightly at night. These clouds are formed from ice crystals and are typically visible during twilight, creating a stunning display in the sky.
