moon halo

A **moon halo** is a beautiful natural phenomenon where a glowing ring appears around the moon. This optical effect is caused by the refraction, reflection, and dispersion of light through ice crystals suspended in thin, high-altitude cirrus clouds. Moon halos often signal changing weather patterns and add a mystical, ethereal touch to the night sky.
