Scott C Waring appears to have added the black square to this image.

Oddly, many people have been left convinced by posts on certain UFO websites and YouTube channels that there may be some credit to the theory.

But, Express.co.uk can expose the latest claims, at least, as nothing more than a digitally-edited hoax.

Scott C Waring, who edits the popular ufosightingsdaily.com, has featured the black cubes on his website a number of times.

His latest post on them, published today featured claims he had found another one in an image taken by the the European space agency’s Solar and Heliospheric Observatory (SOHO), which he found online yesterday.

The images are then published by NASA.

The version of the image shown on Mr Waring's website today, shows a black square, much bigger than earth in comparison to the sun, in the top left corner of the solar image.

Mr Waring posted a blog with the image entitled "Giant Borg Cube UFO Seen Orbiting Sun In NASA Photo".
