According to NASA, the black cubes are, in fact, missing data in the pictures but since flares of the sun partially cover the left side of the cube, we assume that the object appears to be real.
According to conspiracy theorist and UFO hunter Scott C Waring, the black cube makes frequent appearances near the Sun.
Mr Waring shared photos of the black cube to his blog UFO Sightings Daily back in 2016.
The UFO hunter said: “This cube was caught between the SOHO satellite and the Sun. The cube has been seen before off and on.”
Mr Waring went on to suggest the photos could be part of an active campaign to hide the existence of extraterrestrials from the public.
Mr Waring said: “There is also the possibility that NASA is using a black cube to cover-up alien spacecraft that get caught in the SOHO images.”
Curiously, a similar event occurred nine years earlier in the same month, just a coincidence?
