Did you know? The Mysterious Moscow Cloud

A mysterious cloud shaped like a halo appeared over Moscow. When the cloud initially formed, some UFO enthusiasts declared it to be a "true mystery." Some even compared it to the giant spaceship hovering over Earth in the movie "Independence Day." Reality quickly dashed any predictions of an alien invasion. An article from the Daily Mail explains that the "luminous ring-shaped cloud" was simply an optical effect.
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."
