UFOs shut down an airport in China's Zhejiang province and turned heads in a major city, but a renowned space expert says the strange lights in the night sky will likely turn out to be more identifiable flying objects.

Just days after the Xiaoshan Airport grounded flights due to bizarre lights, China's state-controlled news agency published photographs of a mysterious "diamond-shaped" object sighted over Chongqing, sparking speculation about extraterrestrial visitors.
