This is interesting.
Video at link.NASA's live feed of the International Space Station (ISS) captured a mysterious object, which UFO experts claim is an alien cylinder that goes transparent.
The odd shape was spotted in a black space behind the ISS by space fans watching the live feed.
And experts said the cylinder - which they claim was a UFO - was 'partially transparent', which may be a technique used to keep the craft safe so that it is not seen.
UFO expert Scott C Waring, shared the footage and said: "I noticed a UFO in the distance that was coming closer and closer to the space station. The UFO was partially cloaked, which made it look transparent."
