The image appears to show a glowing disc that appears to be emitting light.
The picture was taken onboard a boat passing rough the Hudson River last Wednesday afternoon.
But experts believe the object is likely to just be a reflection of a light on glass as the picture was taken through a window, meaning there was nothing actually outside the camera.
Indoor lights reflected on windowns have been to blame for a number of suspected UFO photographs, particularly, when the photographer says they saw nothing at the time.
“Well, typically people assume equally to aliens in that side of curiosity and locations.
“I am amazed that one thing so massive might simply hover over New York and never even be intercepted by USAF jets.”
And, Scott Waring, editor of UFO Sightings Daily, suggested our military technology was not up to detecting the aliens.
He added: “It simply goes to indicate how previous tech most army radars are.”
