Nasa has released pictures of huge patterns drawn on the ground in Kazakhstan, in an attempt to solve the mystery behind how they got there.
The huge formations are known as the Steppe Geoglyphs. Scientists have little idea how they were formed — but think that solving the mystery could lead to a huge change in how we understand early humans.
There are around 260 of the designs, which are carved into the ground and made out of piles of Earth assembled into shapes that include squares, rings and swastika shapes. The oldest of them are thought to be about 8,000 years old.
The patterns were first spotted by a Kazakh enthusiast in 2007, who saw them on Google Earth.
