Mysterious Lights Emerge During China Avalanche

Astrophotographer Li Shengyu captured mysterious blue flashes during an avalanche on Mount Xian Nairi in China, potentially caused by triboluminescence, a phenomenon where light is emitted when crystals are fractured. This rare observation, also noted by another photographer on Muztagh Ata, could provide insights into avalanche dynamics and ice composition, while posing intriguing questions for molecular physics.
