Definition
A luminous ring or glow surrounding a celestial body, galaxy, or smartphone influencer—basically nature's way of saying "I'm important." This optical illusion occurs when ice crystals in the atmosphere throw light around like a cosmic disco ball, creating a dazzling halo effect that makes even mundane celestial objects look Instagram-worthy.
Example Usage
The 22-degree halo around the moon last night was so stunning that astronomers collectively agreed to skip their calculations and just stare upward like mere mortals.
