Some have already branded the clip definitive PROOF of alien lifeforms.
The video – which is reportedly shot from the International Space Station – shows three unidentified flying objects blast out of Earth’s atmosphere.
The lights leave our planet seconds before the live video feed is cut by NASA due to a reported “loss of signal”.
“BINGO Caught them red handed leaving earths orbit,” one viewer wrote on Youtube “Thats the kind of proof that is needed.”
Another posted on the video sharing website: “Cut the cameras more that just confirms its true.”
The NASA footage – entitled “UFO Mysteries: UFOs, Angels Or Biological Creatures Seen Leaving The Earth?” – appeared online earlier this week.
Of course, its possible the YouTube video has been doctored, or the unexplained objects are simply a trick of the light.
