Mystery of Two Suns in Chinese Sky Leaves Scientists Puzzled

(CHICAGO) - A rare meteorological event occurring over the Chinese skies has left scientists scratching their heads.
Two brilliant suns suddenly appeared in the sky.
One sun, the normal, bright cheerful one that warms the
Earth and lights the countryside continued to slide towards the horizon
as dusk approached. The other "sun" suddenly flared to life. That eerie
interloper shone almost as brilliantly. As large as the original sun,
the new sun differed mostly in color and definition: the impostor was
tinted orange and appeared a bit fuzzy.
Stranger still, people witnessing the strange sight noticed the suns cast double shadows of objects on the ground.
Website "Life's Little Mysteries," as stumped as many
others that saw the phenomena, sought out expert advice from Jim Kaler,
the University of Illinois astronomer that debunked the viral story
about the Orion constellation star Betelgeuse undergoing a supernova
explosion and appearing as a second sun in the sky.
Kaler believes that the second sun that many saw over
China was caused by atmospheric refraction. He admitted, however, that
the phenomena is not fully understood.

After viewing a video taken of the phenomena, Kaler
said: "I doubt it's been computer modeled. There must have been some
blob of atmosphere somewhere that caused this truly spectacular
phenomenon, which in a sense is a mirage."
Not completely satisfied with Kaler's partial
explanation, Mysteries sought out another expert, Grant Perry. An
atmospheric scientist at the University of Wisconsin Cooperative
Institute for Satellite and Meteorological Studies, Perry admitted that
he too is a bit mystified.
"This is not a common optical phenomenon that we're
seeing here," he explained. "I'm asking myself if this is an artifact of
the lens, but if that were the case—if it's reflections of the lens
elements—then the images would move in relation to each other as the
camera moves. But that doesn't happen."
If the peculiar incident was not caused by lens flare
or any understood meteorological phenomena like "sun-dogs"—multiple
images of the sun projected by refraction in the upper atmosphere—then
what caused a second sun to appear?
"You would have to assume it is particles of ice or
something in the atmosphere aligned in such a way that they would
refract the sunlight at that very small angle, but only in one
direction. It would require some fairly peculiar characteristics."
So, scientists believe it is ice after all that caused sunlight to refract and create the image of a twin sun.
A logical explanation, yet one that has not been
proven. The phenomena over China is something so rare that science has
not had the opportunity to fully investigate its properties.
The second sun disappeared at sunset when the original sun set. The next morning, only one sun rose.
No doubt many in China breathed a sigh of relief.
