Noctilucent Clouds at Dusk - Rare Atmospheric Phenomenon #1489981 (License: Personal Use)

This image captures noctilucent clouds-rare, luminous formations composed of ice crystals in the mesosphere, roughly 76-85 km above Earth’s surface. They appear during twilight in summer months at high latitudes, reflecting sunlight from below the horizon and glowing in vivid blues and silvers. Their increasing frequency may be linked to climate change and rocket exhaust emissions.
