Cloud over Moscow

When the first photo of this halo appeared on the internet, skeptics immediately bashed it merely as a photoshopped photo. True UFO enthusiasts call this a "true mystery". Now here's the video to prove that it's none of the above. What is that thing? A tornado waiting to form? A giant UFO the likes of which were seen in the movie Independence Day? Afraid not kids.

It is actually an optical illusion. An official spokesperson for Moscow's weather department said, "Several fronts have been passing through Moscow recently, there was an intrusion of the Arctic air too, the sun was shining from the west — this is how the effect was produced."

So there. No need to bring out your emergency kits just yet. There's no invasion happening. Yet.
