Unexplained Spiral Sightings in Alaska's Northern Lights

A light baby blue spiral resembling a galaxy appeared amid the aurora in Alaska's night sky, caused by excess fuel released from a SpaceX rocket that launched from California. The fuel turned into ice in high altitudes and reflected sunlight, creating a spiral cloud. The appearance of the swirl was caught in time-lapse on the Geophysical Institute’s all-sky camera and shared widely. While not a common sight, similar occurrences have been seen before.
