An online conspiracy theorist and YouTuber shared footage on social media showing a "boomerang-like shape" on the ISS live stream. The video quickly went viral and sparked debate.
In the footage, they claimed that it had been thoroughly examined to ensure authenticity and to avoid any editing tricks.
The YouTuber also captured the "Calvine Photograph," a well-known image from the Scottish Highlands purportedly capturing a diamond-shaped UFO in the sky for about 10 minutes.
However, this case is not directly related to the ISS live stream footage.
The Calvine Photograph showed an object witnessed by hikers for roughly ten minutes before disappearing.
The photographer's negatives were sent to a newspaper and later retrieved by the Ministry of Defence.
The Calvine Photograph remained classified for nearly 30 years before its release.
While the image's authenticity is not disputed, the identity of the photographer and the exact nature of the object in the picture remain unknown.
One person said: I could only see the lights and the way they moved, this is precisely the shape of what I saw in phoenix..it had to be 1/2 mile to 1 mile from tip to tip and it was moving towards us
A second wrote: That UFO footage is incredible. There has been a lot of great UFO video lately of UFOS above the clouds lately. Great video.
While a third commented: Also, to anyone thinking this is US craft... Why in the hell would they fly a classified aircraft above all of that cloud cover in full view of the ISS and all of the foreign satellites? Yea, they definitely wouldn't.
Another added: This is a known aircraft. It is the same type of craft responsible for the Phoenix Lights sightings.
This is not the first case of a UFO object being recorded
While most UFO images are often blurry and inconclusive, this particular picture stands out for its clarity and detail.
Captured in Scotland in 1990, the photograph depicts a diamond-shaped object in the sky, captivating UFO enthusiasts.
The original negatives of the 'Calvine Photograph' were first given to Scotland's Daily Record newspaper, which subsequently passed them on to the Ministry of Defence (MOD).
Holland suggests that the photograph captures a secret military aircraft on a test flight rather than an extraterrestrial craft.
In his theory, he suggests that the diamond-shaped ship seen in the image was part of a radar-proof defense system being developed by British Aerospace.
The Harrier jet spotted in the background, Holland believes, was escorting the experimental aircraft.
