Dunes of Southern Highlands look spectacular! NASA shares the pic

New Delhi: The US space agency NASA has released a beautiful image of sand dunes of Southern Highlands.

According to NASA, Sand dunes are scattered across the red planet and one of the larger populations exists in the Southern hemisphere, just west of the Hellas impact basin.

As per reports the Hellespontus region features numerous collections of dark, dune formations that collect both within depressions such as craters, and among "extra-crater" plains areas.

The image displays the middle portion of a large dune field composed primarily of crescent-shaped "barchan" dunes. Here, the steep, sunlit side of the dune, called a slip face, indicates the down-wind side of the dune and direction of its migration.

Other long, narrow linear dunes known as "seif" dunes are also here and in other locales to the east.
