Self-proclaimed UFO expert captures 'holy grail' evidence during space station livestream

A self-proclaimed UFO expert reckons they've caught the 'holy grail' of evidence in the search for the truth that may or may not be out there.

Are we alone in the universe, and what answer do we really want that question to have?

We're not going to be able to answer that question for you today, but someone with a keen interest in flying saucers and the like claims they've been holding onto a clip of a UFO for the past eight months.

An online conspiracy theorist and YouTuber said they'd spotted a boomerang-like shape on a livestream of the International Space Station.

Sharing the footage on his channel, he claimed that he'd had the video checked over for 'signs of editing' to make sure it was real.

In the video, which was a livestream from the ISS looking at the North Pole from space, a boomerang-like shape appears to move down the screen at great speed.

Naturally, the only answer can be that it's aliens.

The YouTuber said the footage had been provided to them and they couldn't find the original livestream to fully verify it, so really you can draw your own conclusions.

Obviously, that's what the comment section is for, and while some people called it 'incredible', others were far more sceptical.

Someone else denounced the footage as 'fake', saying that the boomerang was moving several frames faster than everything else around it.

Elsewhere in the search for that elusive notion that aliens are out there and dropping in on planet Earth to have a good look at us, a photo of the 'world's clearest UFO' spent decades hidden from the public.

A pair of hikers travelling through the Scottish Highlands took what is now known as the 'Calvine Photograph', and according to eyewitness reports a strange, diamond shaped object hovered in the sky for about 10 minutes before soaring upwards out of sight.

Negatives of the photo were sent to the Daily Record newspaper, and they in turn sent it on to the Ministry of Defence.

From there, the pictures were not released to the public for around 30 years before an academic discovered them during research.

He was able to release the pictures to the public, though it really takes us no closer to learning who exactly took the pictures and what precisely they managed to get a snap of.

If you want to think it's aliens then you go right ahead and think it's aliens.
