A few days ago, an interesting video was taken showing a halo of clouds over Moscow. Some say it is a UFO, some say that it is just a digital illusion while others say it is similar to a scene in the movie Independence Day where a giant spaceship hovers above the Earth.
Now, meteorologists say it isn't a digital effect nor a UFO. Officials from Moscow's weather department say that it is an optical illusion. They claim that "..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."
I don't believe in UFO's but this illusion really rocks. Click here to see the video.
