Devastating wildfires burned through California’s wine country in October 2017, taking several lives and leaving thousands of people homeless. On October 21, the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) on the Terra satellite acquired this false-color image of the burn scars left by the Tubbs (upper left), Nuns (center), and Atlas (lower right) fires. Unburned vegetation appears red; burned vegetation appears brown. Buildings, roads, and other developed areas appear light gray and white.
