This is planet Earth, specifically the Tassili n’Ajjer National Park, a part of the Sahara Desert, taken by the Landsat 7 satellite. Landsat 7 used a combination of infrared, near-infrared and visible light to better distinguish between the various rock types found in the region. Sand appears in shades of yellow and tan, while granite rocks appear brick red, and blue areas are likely salts. This area has a bone-dry climate with scant rainfall, but is not just a sea of sand like the rest of the Sahara Desert. Instead, the rocky plateau rises above the surrounding sand. Rich in geologic and human history, Tassili n’Ajjer is a United Nations Educational, Scientific and Cultural Organization (UNESCO) World Heritage Site, and covers 27,800 square miles (72,000 square kilometers) in southeastern Algeria.
