Alien Proof: NASA captures alien craft almost 300m long above space station | Watch Video

A video captured by NASA’s International Space Station (ISS) live camera on Friday have spotted an alien craft almost 300m long, flying alongside a space station.

The object lurking behind the ISS first pops up as three twinkling lights in a triangular shape, disgorging into an orb-like object before slowly fading into darkness.

The new video was shared on popular YouTube conspiracy channel The Hidden Underbelly 2.0 on April 13.

UFO hunter Scott Waring was quick to point out what he believed to be a 275m long triangular-shaped craft.

The expert says it first shows up as a single glowing orbit.

​"This UFO appeared on live cam and spit out an orb that quickly came closer to the space station. As the orb left the main ship, it was visible.

However, its systems seem to become activated after it left, because it soon cloaked," the YouTube description states.

UFO hunter Scott C Waring of UFO Sightings Daily wrote on his website Sunday, "This UFO is going to blow your mind! It just shows up as a single glowing orb. Then it divides into about 4-6 flashing orbs! During this time, the UFO is partially revealed, meaning it's not 6 UFOs, but one large UFO of about 300 meters diameter."

"The UFO has a more TR3B shape … To see the triangle UFO, pause the video at 1:12 to see it," Waring wrote.

​In his blog post, Waring also speculated that TR3B-shaped UFOs are alien crafts that the "United States Air Force has modified to be flown by humans," suggesting that the spotted UFO was a "top secret government ship."
