This is the moment an eerie black ring hangs over the afternoon sky, spooking onlookers who believe it may be of alien origin.
The apparently supernatural ring-shaped form was filmed moving sluggishly across the sky above an oil facility in the city of Barrancabermeja in the Colombian department of Santander.
The eerie sight, which gave passersby the heebie-jeebies, was registered this week.
In one of several videos filmed by onlookers, one resident is heard saying: “God, that’s very strange, I hope they’re not aliens.”

Another passerby says: “Look at that in the sky, I don’t know what it is.”
Despite the ring appearing to be from outer space, Luis Nunez of the Halley Group Astronomy Complex at the Industrial University of Santander believes there may be a rational explanation.
He told radio station Blu Radio: “These are smoke rings generated by a large structure. Smoke can originate by accident… it could be due to a boat on the Magdalena River or in the oil facility.”
The expert added: “It is an artificial phenomenon, and given the weather conditions, in this case a cloudy day, it appears clearer to people.”
Despite Nunez’ dampening of suspicions, alien visits have been a hot topic of discussion in recent months.
A US government report mandated by then-President Donald Trump last year on sightings of UFOs found no evidence of alien activity, but did not rule it out either.
The report reviewed 120 incidents and was unable to make definitive assessments about what the sighted flying objects might have been.
In May, retired US Navy pilot Ryan Graves told reporters that he and his squadron had seen objects with no visible exhaust plumes travelling at speeds apparently defying the limits of known technology in restricted airspace off the coast of the US state of Virginia in 2014.
