A large, glowing spiral observed in the sky over the UK was believed to be caused by a SpaceX rocket.
The spiral was initially mistaken for an aircraft or extraterrestrial activity, but it was later attributed to a launch at Cape Canaveral Space Force Station in Florida.
The display was caused by the frozen exhaust plume of the Falcon 9 rocket, which appeared to be spinning and reflecting sunlight.
The spiral was visible across Europe, with many people sharing footage and imagery on social media.
