The footage, recorded on November 15, appears to show a number of shiny objects sailing past the ISS in space.
A message is then shown, saying the live feed is unavailable due to “loss of signal” or the cameras being used for “operational purposes” by the space station’s onboard crew.
The clip was shared on YouTube by conspiracy theory channel mavi 777 who claimed the mysterious objects were UFOs that visit Earth every “3,600 years”.
Unsurprisingly, it has sparked a lively debate about whether the footage was evidence of UFOs and aliens or something much more mundane, like space junk.
One UFO believer, who sounded quite convinced, commented: “WOW CLASSIC. If this is real, and it looks it, just WOW!!!!!
“And it’s seconded by the space station and its pathetic knack of cutting out… debunk that!”
Another conspiracy theorist wrote: “That’s convincing every time anything anomalous shows up NASA seems to cut the feed and that’s not coincidental.”
“ISS is fake af,” commented a third viewer, echoing another common conspiracy theory.
In the comments, the YouTuber added: “These Anunnaki ships pass through the solar system every 3,600 years and harvest the earth at the end of a 26,000-year cycle.
“Heavenly texts indicate this.”
More skeptical viewers said it was likely the footage was just showing passing “space junk” or “rock debris”.
This is not the first time conspiracy theorists have accused NASA of deliberately cutting the ISS live feed when strange objects appear.
A “UFO” was said to be “following” the ISS in another piece of footage that was cut.
In another incident, the live feed was cut during a space walk when shimmering objects appeared on-screen behind astronauts.
