Six large UFOs appear to fly past the International Space Station (ISS) while NASA was filming a live feed. The live video goes dead right after the UFOs appear. Conspiracy theorists are again crying cover up, accusing the space agency to be hiding evidence of alien existence.

The unusual 31-second footage taken from the ISS live feed appears to show six large glowing orbs creeping past the space station. The footage then mysteriously cuts to the space station briefing room. Videos like this have been popping up the internet for some time now.

In the live video, the UFOs move from the right of the screen towards the left. Originally spotted by a UFO spotter know as Streetcap1, the clip was shared with a group of UFO experts called SecureTeam10. They then make an investigation using slow motion of the footage when the UFOs appear, and share their findings online.

The SecureTeam says that the video shows what looks like a fleet of unidentified flying objects moving in the distance behind the International Space Station."We have about six UFOs passing behind, and judging from the distance, I would guess that the size of these objects, whatever they are, would be fairly large," the team says. Tyler, one of the team members, elaborates that what they see in the video could not just be ice particles in space as how NASA usually explains these things away, the Daily Mail reports.

The UFOs look much larger. Tyler says that "we must be looking at icebergs". He also remarks on how NASA suspiciously cut the live feed and replaced it with footage from a camera showing the inside of a briefing room.

According to the Mirror Online, an ex-NASA employee, James Oberg, offers some insight in an article posted on Atlas Obscura. He saw the same phenomenon in 1996 when a NASA shuttle lost a satellite in space when its tether broke, leading to a strange sequence of cloud of ice crystals floating around the tether, which many thought were UFOs. So the recent video where UFOs appear might just be particles from space.
