Unraveling the Enigma of the Sahara's Star Dune

Researchers have used radar and other technologies to study a large star dune in eastern Morocco, uncovering details about its formation and development. The study, led by British researchers, used radar to examine the dune's structure and luminescence dating to estimate its age. The star dune is estimated to be about 13,000 years old and is moving at a rate of about 50 centimeters a year. Star dunes make up just 10 percent of all dunes in Earth's deserts and have also been observed on Mars and Saturn's moon Titan.
