NASA photographed an exquisite sand dune on Mars over the summer that's out of this world.

The dune appears blue in an enhanced-color image taken by the Mars Reconnaissance Orbiter (MRO), though it's actually a grayish hue. The visual effect comes from upping the contrast, a trick that allows researchers to see more detail in images of Mars.

The dune is located in the red planet's Lyot Crater, a large crater on Mars that is known for its patterned ground.

"It is made of finer material and/or has a different composition than the surrounding [dunes]," NASA said.

The MRO originally captured the image in January 2018.
