Mysterious blue light spotted during avalanche on Mount Xiannairi, China

A rare and intriguing phenomenon has been observed in China. On the night of October 27th, Chinese astrophotographer Shengyu Li set up his camera to capture star trails over Mount Xiannairi in Sichuan Province. To his surprise, he recorded mysterious blue flashes accompanying an avalanche. 

The exact cause of these "blue lights" remains unclear, sparking various theories. Some speculate they could stem from geomagnetic activity, interactions of cosmic rays in the upper atmosphere, or rare atmospheric phenomena like blue jets or elves. However, Li offers another explanation: the flashes might result from triboluminescence—light produced by friction during ice fragmentation. 

Triboluminescence occurs when certain materials emit light as they are fractured, scratched, or rubbed. This phenomenon happens due to the breaking of chemical bonds or the sudden separation of surfaces, which generates electrical charges. These charges can ionize the surrounding air or excite the material itself, creating visible light. 

The hypothesis suggests that this event could be an example of triboluminescence. However, it also raises the intriguing possibility of a connection to UFO phenomena, such as orbs or other unexplained lights that have been observed around the world over the years. 

Hypothesis: The sighting depicts what appears to be a blue light descending onto a snowbank, following the avalanche as it moves downward, and then vanishing before seemingly ascending again.

 Did the avalanche trigger the blue light, or did the blue light crash into the snow, causing the avalanche? 

Whether this phenomenon is a rare case of triboluminescence, potentially the first instance of it being captured on camera or something linked to unexplained UFO activity, the recording of this light remains a unique and fascinating occurrence.
