Baffling footage purporting to show an object trailing the International Space Station has emerged from Russia.
The video was reported to show a spacecraft or piece of debris following the station as it orbited Earth last month.
The footage - claimed to have been shot on the ISS's own cameras - was said to have been taken while the satellite was waiting for a supplies delivery.
Footage said to show a UFO tracking the Space Station (ISS)
Many have claimed the object is a UFO - but others remain skeptical about the authenticity of the film and the explanations for the object.
Some pointed out that cameras on the ISS record video of significantly better quality than that seen in the short recording.
