   On May 10, 2021, the Moderate Resolution Imaging Spectroradiometer
   (MODIS) on board NASA’s Aqua satellite acquired a true-color image of a
   sunny day over southeastern Europe.

   Glorious deep greens mark forested land, while agricultural fields with
   open soil, ripe for planting, appear tan. Early crops color the fields
   light green. Bits of snow sit atop the high peaks of the Carpathian
   Mountains in Romania and western Ukraine and, further south, across the
   Balkan Mountains of Bulgaria.

   Swirls of phytoplankton stain inky blue waters of the Black Sea. These
   microscopic organisms live in these waters year-round in small numbers
   and, when nutrient load, water temperature, and length of sunshine are
   just right reproduce explosively, creating large blooms that can be
   seen from space. Some of the swirling color may also be from suspended
   sediment.
