In the footage, the editor claims the UFO “powered up” – causing it to glow before it took off.
The clip was also slowed down to show the moment someone blocked the view.
This isn’t the first time we have seen UFOs covered up on the ISS live stream, though.
Last month, an object described as “hundreds of miles long” was seen on the feed, before it cut.
And days later a similar event occurred after a mysterious object was spotted on the stream.
The International Space Station is used as a microgravity and space environment research laboratory.
