A video that went viral in recent days shows not one, not two, but seven Suns in the sky during sunset in China, captivating the internet.

The strange phenomenon was captured on a woman’s phone while she was at a hospital in China.

However, this phenomenon is just an optical illusion. The seven “Suns” weren’t real celestial bodies but images created by the refraction of light through the hospital window glass.
