The footage reportedly shows the so-called' Black Knight Satellite' flying through the sky above the US.
UFO hunters claim the satellite is an object approximately 13,000 years old of extraterrestrial origin which orbits Earth.
It comes after the satellite was recently reportedly filmed moving past the International Space Station and moon.
In shuddery footage posted on YouTube, a large, black object was filmed over Jacksonville, Florida.
The bizarrely-shaped structure is shown with three smaller black objects hovering close to it. The objects then suddenly vanish.
Very odd. To read more and view the video, click here.
