      Summary Author:  Mario Freitas   
      
      The above photo showing the waxing  gibbous Moon was taken on a   
      sunshiny afternoon near  Curitiba, Brazil. Bright areas of the lunar   
      crust correspond to highlands, while the darker ones are  basaltic   
      plains, named by early astronomers as “ maria”, the Latin word for   
      seas.   
      
      As we can see in the photo, in full daylight the basalt seas display a   
      hue of blue that’s due to  Earth’s atmosphere, being just a little   
      brighter than the portion of the Moon that’s not illuminated by the   
      Sun. Lunar highlands are bright enough to appear whitish on photos.   
      This subtle contrast increases when the  Moon is observed in a   
      nighttime sky.   
      
      The annotated image below gives the names of some famous  lunar   
      craters and maria, among them the  Sea of Tranquility, the first   
      location on another world visited by human beings. Photo taken on May   
      15, 2016,   
      
      Photo details: Panasonic LUMIX FZ-70 camera; focal length 215 mm.
