On May 4, 2016, the the Enhanced Thematic Mapper Plus (ETM+) on the Landsat 7 satellite acquired this false-color image of the wildfire that burned through Fort McMurray in Alberta, Canada. The image combines shortwave infrared, near infrared, and green light (bands 5-4-2). Near- and short-wave infrared help penetrate clouds and smoke to reveal the hot spots associated with active fires, which appear red. Smoke appears white and burned areas appear brown.
