Millions of people were without power at the height of Hurricane Matthew, and new photos released by NASA show exactly how significant the outages were.
In three photos, taken Thursday, Friday and Saturday, you can see a large swath of the U.S. eastern coast go dark as the storm churns north.
The photos were taken by the Suomi NPP satellite using infrared imaging systems, NASA said.
Also visible in the photos were the restoration efforts, which relit areas of the outages as crews brought parts of the power grid affected by the storm back online.
