Spiral in the sky likely to be from SpaceX launch

A large glowing spiral visible in the night sky on Monday is believed to have been caused by a SpaceX rocket launch in the US.
The Met Office said the shape was likely produced by a frozen plume of fuel from the rocket’s exhaust, which reflected the sunlight and appeared to spin in the atmosphere.
The cloud-like shape was visible for several minutes above the UK and elsewhere in Europe before fading.
The Falcon 9 rocket from Elon Musk’s space company lifted off at around 13:50 local time in Florida (17:50 GMT) on a classified US government mission.
The Falcon 9 is a reusable rocket. After launching into space, it releases the payload, it is carrying, such as a satellite.
