After examining the image, MrMBB333 came to the conclusion that it shows the landing site of what was once a "flying machine", which, he claims, travelled at high speed and left a gouge in the snow after crashing into it.
The revelations sparked intense debate online with users offering their own explanations.
"To me it looks like the front of a sea ship, maybe it was once water rather than ice and for whatever reason it got stuck or sank," wrote one individual.
"The black triangle looks like the shadow of a pyramid. The triangular indentation at the bottom of the shadow is the southern face, lit up by the sun. There appears to be an encampment off the bottom corner of the right ‘wing’. It looks like a long building and some tents, to me at least," wrote the other.
"Wow, this is crazy weird ... End times are here way already. Get ready for more weird stuff…"
"It's The Thing."
"I don't think anything has crashed in the Antarctic, the snow looks like a natural drift. 'Raised' smooth drifts resemble a crash site with depressions in the snow and rough edges," wrote one netizen.
