An image captured in Iraq shows an elongated shape with a trail behind it. It came from a heat-detecting sensor mounted on a U.S. military system.
The accompanying description says the areas appeared to move across the screen. The mission report describes movement at varying speeds. But the trail may be the result of how the image was processed.
Two Areas in the Frame
The image was captured in 2022. One area appears near the center of the screen. Another is lower down, in the bottom third of the image. It looks elongated, with a trail behind it.
The image description suggests the areas appeared to move from the upper-right corner toward the lower-left. That is the movement depicted in the image, not a video showing what happened moment by moment.
What the Mission Report Said
U.S. Central Command submitted a report about an unidentified phenomenon. It included the sensor image and a mission report. The mission report described the phenomenon as moving intermittently at speeds of about 130 to 290 kilometers per hour.
That range is a speed estimate given in the report. The image itself is a still, so it does not provide a sequence of moments to follow. It shows the two areas and the trail as captured by the system.
How a Trail Can Appear in an Image
The official description says the trail appears behind the elongated area. It also says the effect is consistent with known image-compression and processing artifacts. These are changes a computer system makes to an image, for example when saving or displaying it. The description does not specify exactly what change produced the trail.
What Remains Unknown
The phenomenon’s nature and cause are unknown. The report also does not explain how the speed range was calculated. According to the image description, the trail may be a processing artifact, rather than a real mark in the sky.
An elongated shape remains on the screen, with a line trailing behind it. The trail is in the image, but its origin is still unclear.
