A Russian conspiracy theorist claims these images show the wreck of a giant alien spaceship that crash-landed in Antarctica millions of years ago.
Valentin Degteryov published images of the UFO, which he claims has gone undiscovered because it is covered with snow, after spotting the dark shape on Google Earth.
The UFO hunter, of Nizhny Tagil in the West of Russia, says that the object is of 1900-metres long.
He believes that the wreck is only visible now as a result of melting ice on the earth’s most southern continent.
A video posted by Degteryov has attracted hundreds of thousands of hits since it was uploaded yesterday.
But many dismissed his theories, and said: the form was just a rock on a bare mountain.
Valentin mentioned the coordinates of the object as 73~13’55.09″S,71~57’12.98″W.
It is not the first bizarre UFO theory on the basis of satellite imagery.
In March, a UFO hunter claimed images from Nasa’s Lunar Reconnaissance Orbiter prove there are “mobile alien bases” on the surface of the Moon
Other printers, captured by the Mars Rover Curiosity, turned out to be a green marble scattered about the rocks on the surface of the planet.
