Witness the Ethereal Glow of Noctilucent Clouds

High-altitude noctilucent clouds, a rare phenomenon, offer a captivating celestial display during summer evenings in the Northern Hemisphere.

These mesmerizing clouds, appearing about half an hour after sunset, glow with an electric blue hue as darkness descends.

Their formation remains somewhat mysterious, with theories suggesting links to industrial pollutants and rising methane levels in the atmosphere.

Visible from late spring through early summer, the unpredictable beauty of noctilucent clouds makes them a remarkable sight for stargazers.
