A Colombian radiology specialist says a mysterious metal orb discovered in his country is an unidentified flying object (UFO) of extraterrestrial origin, though experts remain skeptical of the claim.

Jose Luis Velasquez, the radiology specialist, determined the extraterrestrial origin after inspecting the object and finding no marks indicating the metal orb had been welded together or contained joined parts in any way, according to a post on X, formerly Twitter, from a creator who labels their content as entertainment.

The object - known as the "Buga Sphere" - was discovered in Buga, Colombia earlier this year, according to video in the social media post.

Images of the orb show a silver-colored sphere about the size of a bowling ball covered in what appears to be foreign text and drawings.
