This shocking footage is causing quite a stir online.

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”.

Live streams from the International Space Station have triggered hundreds of viral videos claiming to show proof of alien crafts.

Critics claim the alleged UFO sightings on the live feed are simply down to NASA’s poor camera and this latest sighting is, according to the same critics, likely to be a ‘distorted view of the Moon’.
