Satellite imagery shows Ukraine going dark

The Payne Institute Earth Observation Group provided the satellite images for this article about how as Ukraine defends against a Russian invasion, lights across the country have dimmed.  Before Russian forces invaded Ukraine on February 24, nighttime satellite imagery captured the bright lights of Kyiv, Kharkiv, Rivne and other urban areas. Now that same imagery shows a country that has gone dark, steeling itself against a brutal and unprovoked military attack.  We compared the average nightly lightscape of Ukraine in January to February 25, the night after the invasion began, and found a dramatic reduction in lights across the country.  March 3, 2022.
