A youtube video has popped up showing images of what looks to be a dark disc shaped UFO above the ocean, taken from a photograph posted by NASA.
Posted by Streetcap1, the image shown in the video shows a standout black disc in the midst of blue and clouds. It has been lightened heavily from the original dark photo, which brought out the object and made it much more noticeable.
It has received some criticism with some youtube users stating it is nothing more than a weather balloon. Have a look for yourself and make your own conclusions –
Check out the original image here from NASA.
