The US Government has launched a new office to look into reports of UFOs from around the world.
The move was signed into law just before the turn of the year and aims to establish if there is a potential security threat from what is seen in the skies.
Experts will then work to establish if they came from a foreign force - or from a galaxy far, far away.
Senator Kirsten Gillibrand said: “Our national security efforts rely on aerial supremacy and these phenomena present a challenge to our dominance.
“The United States needs a coordinated effort to take control and understand whether these aerial phenomena belong to a foreign government or something else altogether.
The new Unidentified Aerial Phenomena programme was launched after a number of high profile videos were released by the Pentagon - many including US military chasing targets pulling off impossible manoeuvres and speeds.
The move has upset many ufologists who believe the truth about possible visitors have been hidden from the masses for decades.
Ron James, a spokesman for the Mutual UFO Network, said: “We don't see that this means new resources will be dedicated to the matter.
“We believe that considerable resources have always been dedicated to the matter at some level inside deep government and industry.”
It comes as a UFO spotter who monitors the International Space Station’s live feed claimed to have proof of aliens’ existence.
Scott Waring, who runs the website UFO Sightings Daily, said: “Watch this live space station footage taken today and you will see a close up of a huge sphere UFO rising up in earth’s orbit.
“I and others have seen such UFOs orbiting Earths moon, but this event is a very rare one to see orbiting Earth. This UFO is several times bigger than the space station.”
In 2010 Ministry of Defence files showed a UFO was reported hovering over the home of former Tory leader Michael Howard.
The official inquiry into the sighting in March 1997 said: "MoD air defence staff have confirmed that there is no evidence to suggest any unauthorised incursion of the UK air defence region on that date.”
