For many of us, Antarctica is a far-flung continent with nothing but ice. Our perception of this cold frontier may have been wrong all this time.
A white blur deep under Antarctica's icy surface was recently spotted using the Google Earth map.
The discovery, pointed out by YouTube user "Wowforreel" in a viral video, has fuelled speculation that the massive structure buried under the icy continent was an unidentified flying object (UFO) that landed on Earth many years ago, or even a secret government research facility.
The YouTube user even demonstrated how others can locate the mysterious structure, which he described as a "patchy mass" under Antarctica, using the web app Google Earth.
"Antarctica is crawling with weirdness," Wowforreel remarked, as quoted by The Daily Express.
The mysterious structure is estimated to have an area of 14.5 miles by 4.5 miles.
"This thing is so huge you can't miss it—not even from outer space. I've searched the entire continent and I couldn't find anything quite like it," said the YouTube user who noticed the baffling structure.
But the mystery of this object does not end there: Brush-like strokes were also seen on the ice surface on top of it, indicating a conscious effort to cover up the "thing."
"I thought maybe there's a peculiar place in the images where there happens to be a gap, but I don't think that's the case," Wowforreel remarked in the video, which has already been viewed two million times since it was uploaded in 2012.
"If this masking was removed would we see the deck of a giant UFO mothership buried in ice?" he wondered.
Other YouTube users were equally puzzled, with one suggesting that the structure was a secret research facility.
"It's a government facility. They are allowed to request Google to blur out things like this," YouTube user Bonnie said.
