YouTube UFO hunter Streetcap 1 uploaded a short video yesterday questioning if the dark object visible in the image could be the mythical “ancient alien satellite” whose existence is believed by thousands of UFO buffs.
The Black Knight satellite is the name that has been given to an object captured on camera by Nasa astronauts during a 1998 space shuttle mission.
There are alien conspiracy theorists who claim the satellite is an object of extraterrestrial origin, possibly up to 13,000 years old orbiting Earth in near-polar orbit.
Fellow UFO hunter Scott C Waring ran the video on his website ufosightingsdaily.com.
He said: “It’s very dark and has a lot of detail to it.
The ‘Black Knight satellite’ in NASA images, but it was just a thermal blanket drifting in space.
“Its darkness and shape makes it a possibility that this may be a Dark Knight satellite.
“Dark Knight is an ancient astronaut satellite system placed in Earths orbit thousands of years ago to safeguard their (aliens) planet claim.”
But sceptics say the existence of the Black Knight satellite has been debunked many times, and the NASA images show, as the space agency said at the time, a thermal blanket accidentally dropped from a space shuttle.
These include Scott Brando, of website ufoofinterest.org, who said of the latest video: “We don’t know if it is a picture cropped by NASA image or a frame by ISS Live Stream. Usually these “objects” are just reflections from ISS.”
In 2015, YouTube debunker NUA, laid the mystery to rest.
In a video called “Black Knight Satellite UFO Documentary – Truth Exposed 2015 – (Debunked)” – he claims to conclusively prove the ‘Black Knight’, as photographed in 1998 NASA images, was nothing more than the dropped thermal blanket.
Streetcap1 claims this object on the NASA ISS live cam could be the ‘Black Knight Satellite’.

It was lost by the crew of the Endeavor space shuttle as they worked on the developing the International Space Station (ISS).
In his video, NUA compared NASA video of the Endeavor mission which shows a thermal blanket on the ISS.
The same blanket is then seen being dropped by the crew as it tumbles away into space.
He highlights the blanket as being exactly the same shape as the ‘Black Knight’ in the 1998 pictures seized on by conspiracists and explains that the object only appeared to change shape because it was turning as it fell away.
The whole legend of the alien satellite seems to have retrospectively started anyway.
In 1899 Nicola Tesla announced he was picking up radio waves coming from space, prompting people to suggest something alien was out there.
Experiments in 1928 in Oslow, Norway, picked up the same signals.

Its darkness and shape makes it a possibility that this may be a Dark Knight satellite.
In 1954, US state newspapers carried quotes from Donald Keyhoe, a retired naval aviation major and UFO researcher, claiming the US Air Force had detected two satellites orbiting Earth, despite none yet being launched from our planet.
Time then ran a 1960 piece, following the launch of satellites from Earth, stating that the US Navy detected a dark object, possibly a Soviet spy satellite, with a highly irregular orbit.
The myth developed in 1963 when NASA astronaut Gordon Cooper was reported as saying he had seen the Black Knight Satellite while in space, but there was a media blackout upon his return and the US space agency allegedly put it down to cosmic hallucinations.
It has been reported that a decade later in 1973, a researcher from Scotland, Duncan Lunan, looked back at the Norwegian scientists’ data from 1928, before claiming the “messages” suggested the Black Knight was sent by aliens from Epsilon Boötis, as a welcome message to Earth 12,600 years ago.
In 1998, the first alleged photographs of the satellite emerged and were taken by astronauts on the space shuttle Endeavor, as it made its first flight to the ISS.
However, many sceptics claim the legend was retrospectively created after the 1998 pictures emerged, with the preceding odd events weaved into the story to make it more convincing.
The noises from 1899 and 1928 remain a mystery, but the possible causes do not so far include an alien satellite, according to scientists.

They insist research shows that in 1954 Mr Keyhoe had been promoting a UFO book and the articles had been written in a tongue-in-cheek fashion by the papers.
A follow-up, but less widely read, article in Time also confirmed that the strange satellite had in fact been the remains of an Air Force Discoverer satellite that had gone astray, they found.
There are reports that Mr Cooper, although maintaining he saw a number of UFOs in space, never claimed to have seen the Black Knight satellite on that mission or at all.
Yet David Bryant, a UK astronomer and Ufologist, said he had discussed the Black Knight with several Nasa astronauts and one assured him: “It’s a satellite, we just don’t know where it came from.”
And Mr Lunan is also later reported to have denied suggesting any alien satellite had its origins 12,600 years ago and that his conclusion that the noises were a star map were from unscientific methods.
Martina Redpath of Armagh Planetarium in, Northern Ireland, who researched the legend, concluded: “Black Knight is a jumble of completely unrelated stories, reports of unusual science observations, authors promoting fringe ideas, classified spy satellites and people over-interpreting photos.
“These ingredients have chopped up, stirred together and stewed on the internet to one rambling and inconsistent dollop of myth.”
