Antarctica has been studied by numerous scientists. It is believed that structures made by ancient civilizations are hidden beneath the snow.
Google Earth images of an apparent pyramid in Antarctica have stunned scientists around the world.
The startling pictures show a four-side structure which bears an uncanny resemblance to the pyramids of Giza in Egypt.
One of three structures that have apparently been found, it has prompted theories that humanity once inhabited the freezing region.
Two of the so-called pyramids stand roughly 10 miles inland while the other lies closer to the coast.
Scientists have long believed the freezing climate in Antarctica was much warmer thousands of years ago.
In 2009, boffins discovered pollen in the continent, suggesting temperature was once as high as 20C.
And in 2012, scientists form Nevada’s Desert Research Institute identified 32 species of bacteria from Lake Vida, east Antarctica – further suggest the climate was entirely different to the frozen tundra that it is today.
Dr Vanessa Bowman previously said: “Go back 100 million years ago and Antarctica was covered in lush rainforests similar to those that exist in New Zealand today.”
If the structures discovered in the snowy continent prove to be man-made, it could change our understanding of human history.
The construction of Egypt’s Giza – built around 2500BC – has baffled experts for centuries.
While slave labour has been touted as one explanation for the complex structure, several theories suggest they could only have been built with the help of extra-terrestrial beings.
Another theory for the Antarctic pyramids is that it could be a natural phenomenon known as nunatak – when mountain peaks appear up just above massive glaciers.
The incredible images have surfaced just days after another video emerged of a volcanic crater in the region – which UFO hunters were convinced showed alien spacecraft.
