A huge smoke ring
We know what you’re thinking after looking at this picture. ALIENS! We hate to burst your bubble, but extra-terrestrial beings had nothing to do with this. It’s actually a giant smoke ring left by a giant smoker who needs to stop their disgusting habit. We know we’ve been wrong before, and sadly, this is another one of those times.
The real explanation behind this photo is a lot more worrisome. This smoke ring was left there by an exploding transformer. Not the Optimus Prime kind, but rather the cylindrical piece of metal that hangs near the tops of utility poles.
