UFO hunters have spotted an "alien ship" in Google Earth satellite images of Antarctica.
Investigators from a YouTube channel called Secure Team zoomed in on a mountainous region of the South Pole and found what appears to be a disc poking out of a cave.

This sighting was hailed as "final proof of secret technology" on the frozen continent.
"This is a bombshell discovery and one of the most obvious unnatural and anomalous structures we have found at the South Pole," Secure Team said.

Some researchers believe it is the remains of a truly massive asteroid which was more than twice the size of the Chicxulub space rock which wiped out the dinosaurs.
If this explanation is true, it could mean this killer asteroid caused the Permian–Triassic extinction event which killed 96 percent of Earth's sea creatures and up to 70 percent of the vertebrate organisms living on land.
However, the wilder minds of the internet have come up with their own theories, with some conspiracy theorists claiming it could be a massive UFO base or a portal to a mysterious underworld called the Hollow Earth.
This "Wilkes Land gravity anomaly" was first uncovered in 2006, when NASA satellites spotted gravitational changes which indicated the sitting in the middle of a 300 mile wide impact crater.

"To this day, scientists have no idea or way to discover exactly what is buried deep under this thick ice shelf," Secure Team said.
Secure Team suggested the Nazis built secret bases in Antarctica during World War II, which were designed to be used by flying saucers.
The UFO hunters added: "There is some evidence of this coming to light in recent years, which images purporting to show various entrances built into the side of mountains, with a saucer shape and at a very high altitude.
"This begs the question: how would you enter these entrances without something that could fly and was the same shape as hole itself?"
