Noctilucent clouds, glowing electric-blue formations, hover about 50 miles above Earth and are most visible between late June and early August, when the sun’s angle illuminates them. Formed as water vapor condenses around dust from vaporized meteorites, they are common in high-latitude regions like Canada and Europe. While primarily natural, rocket launches—especially from SpaceX—can create or enhance these clouds. Rocket exhaust carried to the upper atmosphere forms ice crystals that develop into clouds, with increased sightings noted after launches between 11 p.m. and 10 a.m. This aids research on long-term changes in noctilucent cloud occurrences. https://www.accuweather.com/en/space-news/noctilucent-clouds-shimmer-in-summer-sky-with-a-possible-boost-from-rockets/1794926
