Each day a different dune. Sand dunes in the Sahara, Algeria

The Sahara spans over 3 million square miles of North Africa, covering large parts of various countries including Algeria, Egypt, Morocco, Sudan, and Tunisia. Vast sand dunes, rocky plateaus, and occasional oases create a landscape like no other. Although it is the largest hot desert in the world, the Sahara supports drought-resistant plants like acacia and palm trees, and hardy animals such as camels and fennec foxes. Intriguing features include its shifting sand dunes, pictured in today's image, some of which are over 500 feet high. Ancient rock art and fossils have also been discovered here, providing insights into early civilizations and prehistoric creatures. Sandstorms are common, shaping the ever-changing scenery and adding to the mystique of this natural wonder.
