The strange ring, which has been branded an eroded rock formation by sceptics, was found in NASA images taken by the Curiosity Rover droid which is exploring the Martian surface taking samples and pictures.
When scaled correctly, the mysterious stone ring fits exactly the dimensions of England’s notorious Stonehenge.
It almost looks as if these rocks were arranged in this circular formation or this could potentially be some sort of ruin that’s part of some larger structure buried beneath the surface.
A NASA spokesman said “it’s such a fascinating formation”
Mars Henge, as it’s been named, looks eerily out of place to the rest of the terrain and surroundings.
