Giant UFO caught by Space Station NASA Cam hovering over Earth, April 15, 2015

A giant UFO was sighted hovering high above Earth by a NASA camera positioned on the International Space Station, according to Scott C. Waring, a prominent online UFO researcher, who revealed his latest purported discovery in a new video posted Tuesday.

''Of all the clouds, this object is floating above the clouds'', Waring says in his narration to the new video. ''It's even higher than the clouds, and it's huge. Look at the size of that!''

''This UFO is trying to simulate the color of the clouds around it. The size of this UFO is 3-10 miles across. If that isn't an indication that humanities ancient radar system needs updating then I don't know what is.''
