A stunning image of sand dunes on Mars, was released this week by NASA.

In the picture, the dunes have an elongated half moon shape. Their shape is the reason why they are known as “barchan dunes.”

In the dunes, the pockmarked landscape of Mars is shown in blue and brown shades.

NASA says the dunes are formed by the wind on the Red Planet, which is constantly moving the grains of sand the long slope to the top of the dune.

The image shows the small ripples on the slope that result from this movement.

According to the space agency, this slow sand movement is what causes the dunes to gradually over time.

In July, newly published research showed that the “spirit of the dunes” on Mars may hold evidence of extraterrestrial life.
