The Mets said that on March 24, the blue spiral seen in the European night sky may have been caused by the SpaceX Falcon 9 rocket.

The Metropolitan Office said the spiral may be caused by a rocket’s frozen exhaust plume that appears to spin in the atmosphere and reflect light, creating a spiral effect. Image source: Joanne Werrell via Story
