      The remote and arid Kufra District of Libya sits at the heart of the   
      Sahara Desert. Filled with sand seas and rugged plateaus, about 91   
      percent of the land in this region is extremely arid desert.   
      Surprisingly, the region also holds a few oases and, thanks to the   
      largest known fossil water aquifer on Earth (the Nubian Sandstone   
      Aquifer), agriculture and palm trees thrive near Al Jawf, the capital   
      of and the largest city in Kufra District.   
      
      More than 20,000 years ago, the landscape of this part of the Saharan   
      Desert was wet, with continuous heavy rainfall that filled the aquifer.   
      The condition of the region has changed considerably since that time,   
      and rainfall in the region is typically less than 0.1 inch of rain a   
      year, making the aquifer that supports farming and lush greenery a   
      non-renewable resource.   
      
      On May 26, 2022, the Moderate Resolution Imaging Spectroradiometer   
      (MODIS) on board NASA’s Terra satellite acquired a true-color image of   
      the Kufra District of Libya. Camel-colored sand covers most of the   
      region, interspersed with plateaus marked with tan tones, brown, and a   
      few light washes of green. The green city of Al Jawf can be seen in the   
      northwest (upper right corner) of the image. The linear green line that   
      ends with a hook is a man-made highway leading to Al Jawf. Near the   
      semi-circular end of the roadway, green circles can be seen dotting the   
      desert. These are areas where water is pumped from the Nubian Sandstone   
      Aquifer and used to irrigate crops. Each circle is approximately 1   
      kilometer (0.62 mile) in diameter.
