Mystery of Sahara’s Star Dune Finally Cracked

Scientists have been puzzled for a long time about how a huge star-shaped sand dune in the Sahara Desert formed. This massive dune, called a "star dune," has arms that stretch out in different directions, unlike regular dunes that just move one way. After lots of research, scientists figured out that these dunes are shaped by winds blowing from multiple directions over time. The changing wind patterns cause the sand to build up in a star-like shape instead of forming a single ridge. It’s been a tough mystery to solve because the winds in the Sahara can be really tricky. But now that scientists have cracked it, they understand how these unique dunes are made!
