UFO hunters are getting excited over eerie footage which may show a glowing alien spacecraft 'jumping through space and time' over Yellowstone National Park.
The clip, captured on a webcam, shows a pulsating orb of light veering through the pitch black night sky above the 3,500 square-mile Wyoming park.
In the video, which has been viewed more than 82,000 times, the unidentified object travels diagonally across the sky before soaring out of view.
A second orb then suddenly appears directly below where the other UFO vanished just moments before.
UFO enthusiast Tyler Glockner uploaded the video to YouTube channel secureteam10.
