Sand dunes across Australia’s Simpson Desert •

Last update: February 16th, 2020 at 8:00 am

Today’s Image of the Day from NASA Earth Observatory features parallel, linear dunes in Australia’s Simpson Desert.

Over thousands of years, the dunes have formed as a result of wind erosion and sand deposition.

Dry lake beds are also visible in the picture, appearing lighter in color due to salt deposits.

In the right corner of the photo, Lake Eyre can be seen with a higher volume of water than usual due to flooding earlier in the year.

The image was captured on May 19, 2019 by an astronaut on the International Space Station.
