UFOs are believed to have flown near China’s Thien Cung station during the renovation in 2011. Declaration of UFOs reappeared in the last few days after the famous conspiracy theorist Scott C Waring shared. My analysis of the video. Mr. Waring, who runs the UFO Sightings website Daily claims the video shows that small UFOs or "alien drones" have monitored the space station. UFO, according to his estimate, is only about 33cm long.

The UFO expert said: "Two UFOs flew through Thien Cung space station. Using measurements and comparisons in photos with UFOs, I think their size is about 0.33 meters. "Small UFOs are moving in the same direction, so they probably watched Chinese people and their activities in space."

From a distance, UFOs look like rectangular pieces of space chips or rubble. Objects seem to be white but Mr. Waring thinks they are transparent and need to be examined more closely.

According to the US Space and Aeronautics Agency (NASA), most of the floating objects in space can be easily explained by natural phenomena. These "UFOs" are often seen from the International Space Station (ISS) or Chinese spacecraft as ice crystals, reflecting light or cosmic garbage.

NASA confirmed: "There are no unidentified objects in the common sense (of aliens) that have been seen from ISS."
