“The object was recorded on live NASA space station cam and has a very strange appearance. It is clear to me that UFOs frequently visit the space station to keep an eye on humanities progress.”
Conspiracy theorists often look for signs of extraterrestrial activity in official NASA videos and live streams.
But scientists who have worked for the space agency in the past have a much simpler explanation for all of the bizarre UFO sightings reported.
According to former NASA engineer James Oberg, most UFO sightings are nothing more than “space dandruff” floating in front of cameras.
These specks of dandruff can be anything from bits of chipped paint drifting aimlessly in zero gravity, flakes of ice or ISS insulation that has broken off.
He said: “I’ve had enough experience with real spaceflight to realise that what’s being seen in many videos is nothing beyond the ‘norm’ from fully mundane phenomena occurring in unearthly settings.”
Mr Oberg argued the human brain is not wired to make sense of these tiny objects floating above Earth.
