A YouTube video has popped up showing a mysterious black ring in the sky, leaving viewers stumped as to what it could be.
16 year old Georgina Heap was at Leamington Spa in the UK playing tennis with her mother when she looked up and spotted the strange phenomenon. The ring, which looks like it is almost made of smoke, was visible for 3 minutes before disappearing.
Theories have ranged from vortex rings to fireworks smoke, to a swarm of insects.
