A bizarre 'megaship' has allegedly been captured by an International Space Station (ISS) camera before Nasa reportedly dims the feed.
Conspiracy theorists are claiming that the footage could have been altered by the independent space agency to make the objects 'disappear'.
In the clip, a long 'cigar-shaped' UFO is seen hovering above the Earth's horizon with two bright reflective-objects sitting just below.
The video was uploaded to YouTube by Streetcap1.
In a caption, he writes: "I thought I was seeing things. I had to be quick.
"The dimming at the end was sudden and my guess is they [Nasa] turned down the brightness a little."
Speaking about the clip, fellow UFO hunter Tyler Glockner, who runs conspiracy site Secure Team 10, said: "We definitely see some anomalous objects, we have this very long cigar-shaped UFO. It's unidentified, we don't know what it is.
"And then below it, we have these two reflective-looking orbs or objects that are obviously under very low resolution because Nasa likes to give us low res videos and keep the high resolution stuff to themselves.
"I have monitored hundreds, likely thousands, of hours of ISS live feed footage and I've seen UFOs, I've seen ice crystals, I've seen space debris and I've seen light reflections.
'What we're seeing here looks like none of those. And it would appear that shortly after these objects come into view, Nasa - either purposely - or the UFOs do it on their own, but the objects quickly dim out.
"So we may have had Nasa dimming the feed, messing with the contrast or the exposure to make these objects disappear from view."
