SpaceX made history last weekend when it became the first private company to launch astronauts into space.
The entire event was livestreamed by both SpaceX and Nasa as the Crew Dragon capsule blasted off from Cape Canaveral and broke through our atmosphere into space.
However, some people are convinced that during the launch something strange took place.
UFO enthusiasts have pointed to a moment on the livestream when a bright light can be seen moving across the feed once the spacecraft is in orbit.
Prominent conspiracy theorist Scott C Waring stated this is â€˜100 percentâ€™ evidence of extraterrestrial existence.
Mr Waring wrote on his blog ET Database: â€˜This is a great capture of a UFO flying past the Dragon SpaceX capsule while it was about to dock at the space station.â€™
â€˜This UFO passed in front of the SpaceX capsule, so we know its small, like an alien drone monitoring history being made.
â€˜Itâ€™s strange that neither Nasa or SpaceX mentions what this strange glowing object is since it came within a few meters of the capsule carrying two astronauts.
â€˜You would think anything that close would be seen as a possible threat to the lives of the astronauts, but nothing was said.
â€˜100 percent proof that alien life exists out there.â€™
His theory has been taken up by a few others on social media.
Unfortunately for alien hunters, former Nasa engineer James Oberg has a perfectly reasonable explanation for the specks seen on the video screen.
He said most UFO sightings are nothing more than â€˜space dandruffâ€™ floating in front of cameras.
These can be anything from bits of chipped paint drifting aimlessly in zero gravity to flakes of ice or ISS insulation that has broken off.
He said: â€˜Iâ€™ve had enough experience with real spaceflight to realise that whatâ€™s being seen in many videos is nothing beyond the â€˜normâ€™ from fully mundane phenomena occurring in unearthly settings.â€™
