In a video uploaded to YouTube, a cigar-shaped object is seen above Earth, with two bright objects below it.

And the two smaller orbs appear to move towards the larger shape.

The, before the footage ends, the UFOs appear to suddenly disappear.

prolific UFO hunter Streetcap1 uploaded the video to YouTube.

Fellow UFO chaser Tyler Glockner who another YouTube channel SecureTeam 10 said of the discovery: 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."

Many viewers were not convinced by the theory.

One posted on YouTube: "probably an old satellite thats space debris.

Another added: Its obviously an airplane distorted the same way you see an image through a clear glass that is round.

There have been several similar claims of NASA shutting the feed when an alleged UFO came into view - but it turned out they were nothing more than light reflected of the ISS itself showing on the camera.

Scott Brando, who runs hoax-busting website ufoofinterest.org said the latest video was just another lens flare anomaly.

He also provided an example of a similar lens flare in another ISS video feed, uploaded by Streetcap1.

NASA denies it has ever seen any UFOs by the ISS, and says the camera only cuts out due to a technical glitch, or changing between different cameras.
