Residents in Milan have been left perplexed by the sudden appearance of a mystery ring of lights in the sky.
Footage shared on social media showed a glowing white ring in the clouds, way above the trees near the historic city in northern Italy.
Some took to social media, speculating that they might have just seen a UFO, or perhaps one of Elon Musk's Starlink satellites.
'A strange phenomenon, lights in the sky #Aliens' one user posted, sharing a video of the lightshow above the city from December 27.
Another shared a photo of the sky captioned 'What are these strange lights in the sky of Milan? Aliens? Inhuman? A portal to Krakoa? A stargate?'
