UFO experts claim a mysterious object captured flying past the International Space Station (ISS) on NASA’s live feed is actually an “alien cylinder”.

Baffling footage shows the item suddenly appearing out the window of the space station, getting closer before fading away.

Conspiracy theorist Scott C Waring, who runs UFO Sightings Daily, shared the footage, writing: “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.

“In the deep blackness of spaces, blending into the environment means you will be safer from other alien species that may not be friendly.”
