“This is easily the strangest thing I have ever witnessed in my life,” says the person who captured this weird video taken of an iceberg of the coast of northern Canada. But it has an explanation.
From the YouTube post:
I noticed what appeared to be a chunk of ice just barely attached to an iceberg, hoping to catch it collapse I took out the camera and zoomed in. What you can see is a white object not attached to the iceberg, but rather spinning around and changing shape? There was no fog and it was a perfectly clear day so I’m up for debate. So any ideas what this could be I’m open to all opinions, ufo, illusion or what?
It is strange alright. Nature can pull some tricks on our vision. This has a logical, optical, physical explanation.
Environment Canada’s Rodney Barney says:
“Mirage effect due to marine layer temperature inversion,” Barney said via Twitter, shortly after the video was posted by CBC News.
The ice and cold water near the surface cools that air. Warmer air above creates a temperature inversion. This situation is not typical but is common. The density difference between the cold and warm air layers creates a lens in the atmosphere that refracts light and produces a mirage.
A Fata Morgana is one such kind of optical illusion. Check out this pic of a ship floating above the water. Such an illusion may be the source of the famous “Flying Dutchman” legend. It is common in polar regions. It is also often mistaken for a UFO. So, we can’t blame the guy for being a little freaked out by this view. It’s really neat. Remember, natural explanations may not be so obvious but they do make sense if we know what the conditions might be.
