NASA photographed a group of magnificent sand dunes on Mars during the summer, and this is outside the world.
The sand dunes appear in blue in an enhanced color image captured by the Mars Reconnaissance Orbiter (MRO), although in fact it is a gray color. The visual effect comes from increased contrast, a trick that allows researchers to see more details in Mars images.
The sand dunes of Lyot Crater are located in the Red Planet, a large Mars pit known for its carved earth.
"They are made of finer materials and / or have a different composition than the ocean [dunes]"NASA said.
MRO captured the picture in January 2018.
Correction: This post has been updated to explain the origin of the blue image.
