The bizarre video, taken in Houston on New Year’s Day, shows three bright lights slowly moving across the night’s sky.
They seem to remain in a perfect triangular formation – sparking claims from some believers they actually formed one singular craft.
The clip was initially shared by Stephaine Westerfield on YouTube on January 3, where she said: “Not sure what these lights are.”
It has since been picked up by numerous conspiracy channels, sparking a frenzy among viewers.
One person who saw the strange video commented: “It is a large triangle-shaped craft, like many that are being seen all over the world.”
Another suggested it could have been the alleged TR-3B spy plane.
The TR-3 Black Manta is the name of a surveillance plane of the United States Air Force, speculated to have been developed under a black project.
It is said to be a supersonic stealth spy plane with a triangular design.
To add more mystery to the shape, another triangular UFO was apparently caught on camera above the village of Ilion in New York state.
The person filming the clip claimed they saw a red “orb” being dropped from the object moments before they started recording.
What they did capture seemed to show a line of three white lights in a triangle shape slowly moving across the daytime sky.
As with many UFO sightings, some sceptics have suggested the objects could just be drones or kites.
But the clips come at a time when interest in UFOs is at an all-time high.
Over 2019, Daily Star Online reported on a series of bizarre snake-like UFOs being spotted in eight states across the country.
And a number of former US Navy soldiers came out last year offering intriguing insights into the infamous USS Nimitz UFO .
