A tantalizing set of photographs circulating online purportedly show a remarkably clear diamond-shaped UFO hovering in the sky over a plain in Argentina. The jaw-dropping pictures (seen in the video above and isolated below) were posted on social media last week by Argentine journalist Calaverita Mateos. In sharing the photos, he claimed that they were taken in the town of El Escorial and subsequently "sent to me by a resident of the plateau, who asks to protect his identity." When pressed on if he could provide the images in their "original format" for analysis, Mateos indicated that "I'll do my best, but I'm not authorized" and went on to explain that the witness was a "field worker" who "does not want to have anything to do with exposing himself so much."

Although the person behind the camera and the circumstances surrounding the sighting remain a mystery, the photos have understandably caused quite the stir in UFO circles by virtue of their remarkable clarity. To that end, the first picture shows what appears to be a metallic-looking diamond-shaped object in the sky, while the second photo is of what one presumes is the same object turned sideways and appearing as singular dark form. The third image appears to show the UFO departing the scene and the final photo sees the object reduced to a mere blur on the horizon as it flies away.

As one might imagine, response to the images has been varied with some UFO enthusiasts arguing that the photos are a fantastic glimpse of an object from out of this world and other observers have suggested that the oddity could be a clandestine military craft. Skeptics, on the other hand, posit that the pictures are simply too good to be true and, as such, they posit that the 'UFO' is probably a clever fabrication. With that in mind, what do you think of the very weird photos our of Argentina? Weigh in with your thoughts on the case at the C2C Facebook page.
