Unveiling the Secrets of Earth's Enormous Moving Star Dunes
Scientists studying a star dune in the Sahara Desert have uncovered surprising insights into its age, growth, and movement. Using radar scans and sand grain analysis, they found that the dune's base formed around 13,000 years ago, with most of its growth occurring over the past 1,000 years. The research also addressed the mystery of the scarcity of ancient evidence of star dunes, suggesting that eroded parts of their preserved structures may have been previously identified as remnants of other dune types.
