Additionally, there is no explaination for this seemingly supernatural formation. Witnessed by millions in Moscow who braced themselves for a close encounter, scientists and officials are saying that it is some kind of optical illusion. The halo can only be explained away as an anomoly of clouds due to a combination of differing air temperatures.
UFOlogists and eyewitnesses have another answer, believing that it must be a space ship. Chemical weapons and pollution have been ruled out and in this case, it seems that no one has a good answer for the unusual sighting. The internet is flooded with images and video taken of the ominous formation by pedestrians and drivers, compelled to stop and marvel at its incredible appearance.
The only thing we can say for sure, is that something very large and strange did appear over Moscow and there were many witnesses to this sky born vortex of light and clouds. While many are comparing it the appearance of the spacecraft in Hollywood movie, Independence Day, the only thing that everyone can agree on- is that this UFO like apparition, is real.
