NASA Landsat 7 satellite imagery revealed a giant circular structure about 200 kilometers in diameter, resembling an eye staring into space. It has been called the Antarctic Great Eye or Wilkes Land gravity anomaly. Conspiracy theorists have called it a giant machine hidden inside a meteorite crater or an entrance to an inner-earth civilization.

Debunked
NASA's official explanation is that it is a subglacial geological structure with a gravity anomaly, possibly the remnant of ancient volcanic activity or a mantle plume or impact structure. No evidence supports the "mechanical device" or "inner-earth entrance" interpretation.
