WATCH: Live NASA feed captures 'cloaked' UFO floating through space

Footage captured by NASA shows a cylinder-like UFO, which conspiracy theorists claim could be evidence of 'alien life'.

The floating object can be seen travelling towards the International Space Station. UFO Hunter Scott Waring shared the video on his YouTube channel, explaining his theory.

The astro-biologist believed the footage showed evidence of cloaking technology.

It's also been suggested that it could just be "space junk".

Waring's video has since had almost 42,000 views and several comments.

"I noticed the UFO in the distance that was coming closer and closer to the space station," he wrote on his blog.

"The UFO was partially cloaked (covered or concealed from distant observers) which made it look transparent."

"In the deep blackness of spaces, blending into the environment means you will be safer from other alien species that may not be so friendly. Bob Lazar said in Area S4 (inside area 51) that he read documents that said the USAF knew of 56 space faring species."

However, Mr Waring's comments have caused some debate with Youtube users commenting that it probably isn't anything exciting.

"Clearly a lens flare - I believe in UFOs but this was not one lol ," one user wrote.

"Hmmm, looks like some kind of gas formation that slowly dissipates ," someone else said.

Mr Waring replied with "maybe, but it seems to move toward the space station from far away. The ISS is moving too fast for it be gas".

This isn't the first time people have been skeptical about what's been captured on camera in space.

Hundreds have taken to the internet to share their ideas on what UFOs sighted in space could be.

Many have claimed the US government and NASA are "hiding" what's really out there.

In January this year, a video posted by Youtube by user Streetcap1 showed a bright light appear before the camera panned away from it.

"NASA spotted this appearing and started to move the camera slowly to the right. Whatever it was it has not reappeared to the best of my knowledge," Streetcap1 said.

One user questioned why they would pan the camera.

"I don't see the point of panning the camera if they have nothing to hide. It's already been seen," they said.

Another user commented: "Yet they will still tell more lies till they are blue in the face. "
