A strange spiral-shaped cloud has left experts scratching their heads.
The cloud, which resembles a jet’s vapor trail or a rocket launch, was photographed last week on Salisbury Plain in Southern England.
SWNS reports that neither U.K. defense officials nor university weather experts have been unable to explain the cloud. The image was taken near a Ministry of Defense testing range. However, the U.K’s Defense Infrastructure Organization is not aware of any exercises that could have caused the cloud.
The cloud sparked discussion on Twitter as users attempted to find out how the spiral formed.
