'UFO spotted' in NASA video of astronauts as they carry out their repairs to the International Space Station

A UFO photobombed astronauts making repairs to the International Space (ISS) earlier this month - setting off a wild frenzy of speculation online. The spooky incident happened on October 7, when Flight Engineers Reid Wiseman of NASA and Alexander Gerst of the European Space Agency conducted a spacewalk outside the International Space Station to fix an electrical problem. In YouTube video shot by NASA and uploaded last week, the UFO can be seen hovering just for a few seconds behind the astronauts, before the camera cuts to another angle.
