Unexplained Blue Flashes Emerge During Chinese Avalanche
A Chinese astrophotographer, Shengyu Li, captured a mysterious blue flash during an avalanche on Mount Xiannairi, which is believed to be caused by a triboelectric effect—a friction-induced phenomenon. This rare occurrence, linked to electromagnetic emissions from cracking ice, was not visible to the naked eye but appeared in Li's photos. The phenomenon, previously documented in scientific literature, was also captured by other photographers in a similar event on Muztagh Ata mountain.
