In the clip, uploaded on YouTube by paranormal channel The Hidden Underbelly 2.0, the alleged UFO appears from this perspective to bea white orb hurtling away from Earth.
Moving very quickly, the object appears in the top and middle of the frame, above the Earth’s horizon.
The YouTube user claims it travels “directly below” the International Space Station (ISS).
He says: “At first glance, it would seem that it came either from our planet or from the far side of the planet but that’s not the case of this object.
“This object is flying directly beneath the ISS.
“It passes right underneath and it shoots past our planet and it goes out into deep space.”
The YouTube user says it is easier to see in a clip he has cleaned up.
“Now, when you come to the enhanced footage, you will be able to track it and see this thing move,” he says.
The video has been watched more than 1,000 times since it was uploaded yesterday, with many conspiracy theorists saying it was clear evidence of alien activity.
“That could be a UFO. It’s moving too fast to be a satellite,” commented a sharp-eyed fan.
Another enthused viewer wrote: “Nice video man!!! That thing was moving right under the ISS!!! Nice one!!”
“We’ve been being watched for thousands of years, why don’t they communicate with us?” mused another believer.
Meanwhile, a flat-Earther who believes all space travel is hoax commented: “Air bubble because the filming is done in the NASA pools.”
It is quite common for distant moving objects to appear in the ISS live-feed, with an estimated 670,000 bits of space junk measuring 1–10 cm and 29,000 larger pieces in orbit around our planet.
This comes after dozens of flashing objects were spotted zooming over Earth on the ISS live feed – sparking a frenzy of wild theories.
And a strange white orb was recorded flying “over NORAD military base” in Colorado, US.
In even stranger news, the US Navy veteran who saw the mysterious Nimitz UFO claims “there is a longer video” after Pentagon released the official footage.
And bizarre footage has shown what a conspiracy theorist calls a “UFO armada” appearing in the skies above Utah near Nellis Air Force Base.
