And you thought rainbows were cool. A few days ago, a mysterious cloud shaped like a halo appeared over Moscow, and the buzz has yet to break. We're the first to admit that a photograph of the heavenly cloud appears to be photoshopped. It's just so...perfect. But meterologists have spoken up and said the cloud wasn't digitally altered. However, it wasn't exactly what it appeared to be, either. 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." The cloud loomed last week, but the searches are still soaring. Lookups on "halo cloud" and "moscow cloud" are both booming, and a video clip has garnered hundreds of thousands of views on YouTube.
