[DS] The footage, taken from a live stream from the International Space Station, a bright golden light is seen “over 200 miles” away from the camera.
It remains in the same place as the ISS orbits around the Earth.
But before viewers see any more of the mystery object, the video is cut.
A message flashes across the scene, saying: “The High Definition Earth Viewing experiment is either switching cameras, or we are experiencing a temporary loss of signal with the International Space Station.”
The clip was posted by alien enthusiast Streetcap1, who titled it: “Massive Golden UFO orbiting Earth.”
He went on to write: “I thought I was seeing things at first then quickly started recording.
“To my surprise they cut transmission, anyway this has to be huge whatever it is.
“If it were a building it would be hundreds of miles long.”
Thousands of people have seen the clip, with some speculating it is “alien-related”.
Another posted: “There is something there and it is very odd.”
But others are less convinced.
Scott Brando, a UFO hoax investigator who runs ufoointerest.org, told Express.co.uk: “I think this is a reflection of sunlight through clouds.”
