In a batch of photos posted to the photo sharing session of Russian website Netall.ru, one of the strangest cloud formations ever is detailed in a handful of images snapped around a 20 mile stretch of the city. As you can imagine, this has stirred up some interesting conversation as to what could be the cause of such an event. As of now, sky-savvy internet sleuths believe the strange clouds were caused by contrails, or thin artificial cloud formations caused by the water exhaust emitted from aircraft. You’ve more than likely seen them in the sky on a regular basis, but rarely in such a striking form.
We’re not saying it was aliens, but well.. you know.
