A newly surfaced video from Beijing posted on Chinese social media by Tang Xiao, appears to show an unusual cylindrical object hovering high above the city’s skyline, reports www.coasttocoastam.com.

Recorded from a moving vehicle, the footage provides a close-up view of the object, which displays intermittent illumination—either from lights on the object itself or from the reflection of sunlight on its surface.

The lack of surrounding reference points in the video, a result of Xiao’s close-in filming, makes it challenging to estimate the size and distance of the object.
