A strange cylindrical UFO has been captured on a live feed taken from the International Space Station, claim conspiracy theorists.
The UFO hunters believe it shows that visitors from other worlds have developed cloaking technology.
But one expert says space junk or a satellite are more likely explanations than apparently ‘unreliable’ cloaking devices.

A live feed taken from the International Space Station appears to show a strange cylindrical UFO approaching the station, before fading away. And the UFO spotter who shared the footage believes is evidence of cloaking technology
According to the Institute of Physics, metamaterials which can bend electromagnetic radiation such as light around an object to give the appearance that it isn’t there.
To date some researchers have used such properties of metamaterials to create devices that can bend certain forms of radiation, such as near-infrared radiation.
So far, however, producing the same effect with visible light has proved more of a challenge.
The footage appears to show the object suddenly appearing near the space station, before starting to approach it.
Part of the cylinder is then seen to disappear, which the UFO spotter who shared the footage believes is evidence of cloaking technology.
Speaking on his blog UFO Sightings Daily, astro-biologist Scott C Waring said: ‘I noticed a UFO in the distance that was coming closer and closer to the space station.
‘The UFO was partially cloaked, 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 that the USAF knew of 56 space faring species.’
The video, shared on YouTube, had attracted over 20,000 views at the time of publication.
But UFO expert and author of the UFO Investigations Manual Nigel Watson believes a more simple explanation is likely.
He said: ‘If alien spacecraft buzzing the ISS use cloaking technology it isn’t very reliable if they keep appearing and disappearing.
‘You’d think by now they could easily avoid our cameras and other sensing technology!
‘This latest video looks like it is either a distant satellite, or a piece of space junk that is relatively close to the camera.
‘Rather than cloaking technology it has probably gone out of sight by moving out of the glare of the Sun.’
This is not the first time that strange objects, argued to be evidence of aliens, have been spotted near the International Space Station.
Over the past year, there have been a growing number of sightings of unidentified objects on Nasa feeds, and some have even claimed a cover-up of the existence of extra-terrestrial life.
The most recent took place back in March, when another video was uploaded to YouTube.

It showed a long bright light hovering above earth with two mysterious bright objects just below.
Conspiracy theorists suggested that this was an alien ‘megaship’, which they claimed Nasa tried altered the lights to make the object seem to disappear.
While it is not always possible to determine exactly what these objects are during the brief period they appear in the stream, there are a number of possible explanations for these types of sightings.
‘It is astonishing how many UFOs are seen buzzing around the ISS, but like this video there is usually a simple explanation for them,’ Nigel Watson, UFO expert and author of the UFO Investigations Manual, told MailOnline after a similar sighting in January.

‘This could well be a lens reflection that appears and then goes as the light changes, giving the impression of an extraterrestrial space coming into view and then cruising out of sight.
‘Many UFOs caught by the ISS’s cameras can be also be explained as images of space junk or satellites in the distance, and even very small flecks of paint or particles can appear like UFOs when caught by the bright light from the sun.’
In the past, a Nasa spokesperson has explained: ‘Reflections from station windows, the spacecraft structure itself or lights from Earth commonly appear as artefacts in photos and videos from the orbiting laboratory.’
DO YOU BELIEVE IN CONSPIRACY THEORIES?
People who doubt the moon landings are more likely to be selfish and attention-seeking, according to a study earlier this year.
Over the course of three online-based studies, researchers at the University of Kent showed strong links between the belief in conspiracy theories and negative psychological traits.
Writing in the journal Social Psychological and Personality Science, the team explained: ‘Previous research linked the endorsement of conspiracy theories to low self-esteem.’
In the first study, a total of 202 participants completed questionnaires on conspiracy beliefs, asking how strongly they agreed with specific statements, such as whether governments carried out acts of terrorism on their own soil.
Alongside this, they were asked to complete a narcissist scale and a self-esteem assessment.
The results showed that those people who rated highly on the narcissism scale and who had low self-esteem were more likely to be conspiracy believers.
This is just the latest in a series of claims Nasa footage shows UFOs before cutting out.
In footage from the ISS channel uploaded to YouTube by user ColdPyro in November last year, a white speck can be seen emerging from the darkness just above Earth’s horizon.
Right before the ‘UFO’ travels out of view, the feed cuts to a grey screen, followed by a statement asking users to ‘please stand by’ due to technical issues.
