Egypt, under Muhammad Ali and his successors, conquered Nubia in 1820–22, founded Khartoum in 1823, and conquered Darfur in 1874. Egypt, including Sudan, became a British protectorate in 1882. Egypt and Britain lost control of the Sudan from 1882 to 1898 as a result of the Mahdist War. After its capture by British troops in 1898, the Sudan became an Anglo-Egyptian condominium. When moisture-laden air hits a mountain range, it is forced to rise. The air then cools and forms clouds that drop moisture on the windward ( wind-facing) slopes. When the air moves over the mountaintop and begins to descend the leeward slopes, there is little moisture left. The descending air warms up, making it difficult for clouds to form. The Atacama Desert, on the Pacific shores of Chile, is a coastal desert. Some areas of the Atacama are often covered by fog. But the region can go decades without rainfall. In fact, the Atacama Desert is the driest place on Earth. Some weather stations in the Atacama have never recorded a drop of rain.

Desert regions often have minimal light pollution, providing a dark and unobstructed night sky view. This pristine darkness allows for better visibility of meteors. It is known for its clear, dry air, which reduces atmospheric interference and enhances the visibility of meteors streaking across the night sky. Next, employ long exposure times ranging from 20 to 30 seconds. This extended exposure gathers ample light from both the stars and the natural landscape illumination. To allow maximum light into your camera, open your lens to its widest aperture, such as f/2.8 or lower. Deserts are found on every continent and cover about one-fifth of Earth’s land area. They are home to around 1 billion people—one-sixth of the Earth’s population. Gearon, Eamonn (2011). The Sahara: A Cultural History. Signal Books (UK), Oxford University Press (US).One theory for the formation of the Sahara is that the monsoon in Northern Africa was weakened because of glaciation during the Quaternary period, starting two or three million years ago. Another theory is that the monsoon was weakened when the ancient Tethys Sea dried up during the Tortonian period around 7 million years ago. [28] Largest Desert in the World".

The Atlantic coastal desert is a narrow strip along the Atlantic coast where fog generated offshore by the cool Canary Current provides sufficient moisture to sustain a variety of lichens, succulents, and shrubs. It covers an area of 39,900 square kilometers (15,400sqmi) in the south of Morocco and Mauritania. [44] There were three or four other moist periods in the Sahara. Similar lush conditions existed as recently as 25,000 years ago. Between the moist periods came periods of dryness much like today’s. These nighttime hunters help the desert ecosystem stay harmonious, adapting and thriving under the starry sky. 8. Orion Constellation – Prominent Winter Marker in the DesertThe South Saharan steppe and woodlands ecoregion is a narrow band running east and west between the hyper-arid Sahara and the Sahel savannas to the south. Movements of the equatorial Intertropical Convergence Zone (ITCZ) bring summer rains during July and August which average 100 to 200mm (4 to 8in) but vary greatly from year to year. These rains sustain summer pastures of grasses and herbs, with dry woodlands and shrublands along seasonal watercourses. This ecoregion covers 1,101,700 square kilometres (425,400sqmi) in Algeria, Chad, Mali, Mauritania, and Sudan. [46] The Desert’s Night has rich stories and traditions that have fascinated indigenous people for ages. Indigenous desert cultures developed intricate star lore. They used the night sky as a celestial roadmap and wove stories around constellations for navigation and cultural identity. The 10 Largest Deserts In The World". WorldAtlas. 13 October 2020.

The flora of the Sahara is highly diversified based on the bio-geographical characteristics of this vast desert. Floristically, the Sahara has three zones based on the amount of rainfall received – the Northern (Mediterranean), Central and Southern Zones. There are two transitional zones – the Mediterranean-Sahara transition and the Sahel transition zone. [50] a b Kay, Andrea U. (2019).

Sand blows off the surface, of course, but the essential shape of the dunes remains intact, probably due to the moisture leaching up into the base of the dunes from the surrounding sabkhas. [5] :213 Lake beds [ edit ]
