NASA space station videos are turning up more sightings of ISS UFO sightings in 2015. One Australian YouTube researcher called, "blubeard2011" had been looking for a UFO orbiting the earth, about 250 miles above the earth's surface and he presumably found a "fleet" of UFOs.

But The Inquisitr reported that the UFO in question was a "doozy," There are also conflicting reports that these NASA ISS UFO sightings in 2015 are secret projects by the government, while other reports say that NASA, the government's space agency is collaborating with the outer space aliens. And some researchers believe that UFOs are spying on NASA's ISS.

The NASA ISS UFO sighting in 2015 by the Australian archivist is the latest in a string of sightings that have been identified on the NASA ISS video feed.

Alien hunters said they have been seeing sightings almost every day. And YouTube and paranormal sites have been publishing videos of the sightings. While there are YouTubers monitoring NASA's video feed, critics cite that blurbs on NASA's vidoe footage are mistakenly dubbed 'NASA ISS UFO sightings in 2015.

Another NASA ISS UFO sighting in 2015 posted on YouTube by prominent NASA ISS UFO 2015 said: "The object could be a UFO or it could be a top secret project that NASA is involved with," said alien conspiracist Scott C Waring, reported Exprtess.co.uk.

While there is a conspiracy theory that the International Space Station was set up to collude with alien beings, ISS video feeds monitored by astronauts at the station could also be turningout distorted images of events happening near the ISS. NASA has been accused for filtering its livestream feed from the space station, allegedly "deleting" images of what appears to be aliens or alien vehicles near the space station.
