Alien hunters say a fresh sighting of a mysterious black ring in the sky shows earthlings may not be alone in the galaxy.
The latest “smoke vortex” – believed by some to be a Unidentified Flying Object — was seen by Kimberley Robinson, who was driving in Yorkshire, England Sunday with her boyfriend.
The 22-year-old captured a photo of the strange black mark on her camera’s phone.
“We hadn’t ever seen anything like this before,” she told a local reporter after uploading the photo to social media. “We have looked into it and no one knows what it is.”
The photo shows what appears to be a giant black smoke ring, but local fire authorities said there had been no reports of fire in the area.
A similar black ring was spotted hovering over Disneyland in California last year and in 2015, footage emerged of a 320 feet-wide ring of smoke floating over Kazakhstan.
Nigel Watson, the author of “UFOs of the first World War,” said he believes the rings are being made by flying objects from another planet.
“Smoke rings in the sky like this one look very spooky and unusual,” he told the MailOnline.
Prominent UFO blogger Scott C Waring said he’s convinced the these marks are made by a type of extra-terrestrial space craft.
“Ring UFOs are super rare, but they have been seen,” he said about the Disneyland sighting.
He said it “causes the family to worry about an alien invasion.”
Alien theories aside, the recent Yorkshire sighting may have been caused by a nearby World War II battle re-enactment – complete with pyrotechnics – that was staged in the area earlier in the day.
“We had our WWI re-enactment on the Saturday and our WWII one on the Sunday, and that plume is actually from the WWII battle,” Sarah Clarke, an organizer for the Yorkshire Wartime Experience, told Express.co.uk.
