I can immediately tell this photo has been uploaded to social media, and it has been compressed to a lower resolution in order to load quickly on social feeds. If you zoom into the image as I did, you can see a lot of compression artifacts surrounding the area where the light poles and trees meet the sky. In instances where objects have been photoshopped into an image, such imperfections can occur where an object has been cut out and manipulated into a preexisting image. The artifacts are more precise surrounding the light poles, and less so surrounding the treetops. The inconsistent nature of these pixels are more characteristic of image compression than an object being collaged into a photograph. There are also no imperfections surrounding the object in the sky, which makes me believe that, whatever it is, the flying thing was actually present at the time the picture was taken. I don’t know what they saw, but as far as I can tell this image is authentic.
