Look at this bizarre phenomenon. it resembling a city that appears to be floating on a cloud. Often these kinds of phenomena are explained as something otherworldly, like a projection from a parallel universe.
Perhaps some of these phenomena are indeed related to supernatural activities, but in this case it is an upward projecting mirage.
The optical phenomenon occurs because rays of light are bent when they pass through air layers of different temperatures in a steep thermal inversion where an atmospheric duct has formed. Nevertheless, it is fascinating to witness such a spectacle in the sky.
The "city in the sky" starts at 8.50 minutes in the latest video of MrMb333 who also reports on various other topics such as the enormous plume of dust, already nicknamed "the gorilla dust cloud" from the he Sahara desert in northern Africa which has been traversing the atmosphere, thousands of feet above the Atlantic Ocean, and now closing in on the southeastern United States.
