The unidentified object appeared on live footage streamed from the International Space Station.
The clip has since been posted on YouTube by user Streetcap1 and shows what appears to be a small white disc flying near to the space station.
This isn’t the first time that the space station cameras have captured mystery objects.
The web cams have led to a string of YouTube uploads from alien hunters claiming to have captured images of alien craft.
However, sceptics claim the alleged UFO sightings on the live feed are simply down to NASA's poor camera and this latest sighting is likely to be a distorted view of the Moon.
