SpaceX rocket exhaust created desert "jellyfish UFO"

A "jellyfish UFO" seen over the US desert Monday night was identified as the exhaust trail from a SpaceX Falcon 9 rocket launch. The phenomenon baffled many observers. The rocket, launched from Vandenberg Space Force Station, created a visible cloud of condensed water vapor as its exhaust interacted with the atmosphere. The launch occurred shortly after sunset, illuminating the plume. This "jellyfish effect" is a common occurrence during rocket launches, caused by the condensation of water vapor. The launch was part of SpaceX's Starlink mission to expand global internet coverage.
