THIS is the moment a gigantic "alien spaceship" is filmed monitoring the International Space station (ISS), according to UFO experts.

Footage from the ISS livestream, uploaded to YouTube, shows a massive hazy object come into view in the background away from the space station. Commentators have described it as first appearing as a line of orange lights, before it begins to take on a larger form.

As the clip comes to the end, the lights appear to dim back into space. The video was released by brothers Blake and Brett Cousins who run YouTube channel ‘thirdphaseofmoon’ yesterday. The pair showed an interview with a UFO expert in an effort to identify the mysterious anomaly.

n the video the expert says: "First, what I was looking at is I don’t know exactly what I was looking at. “In the very beginning, you see these orange dots around it and by the end of it the entire thing almost shrinks up a little bit. “Almost as if it’s a giant mothership for all we know.”

There have already been more than 40,000 views of the video. One viewer said: “Looks like the Battlestar Galactica just jumped into orbit.”  

Another said: “It’s an interstellar mother ship, watching what NASA is doing, as NASA have lied since the first encounter with UFO.”

But a skeptical third said: “To me it looks like the ISS filmed a storm in the upper atmosphere.”

Thirdphaseofmoon has made it onto a number of UFO website and YouTube channel blacklists by more skeptical investigators, amid claims they use hoax and misrepresented footage.
