Earth at night is gorgeous, but did you know these nighttime views are also super useful? NASA and NOAA satellites can detect nighttime lights on Earth. This imagery can identify blackouts after a disaster to help emergency responders know where to direct aid or track lights on fishing boats to monitor fishing regulations. They can even help us track space weather — which means better aurora forecasts and better plans for impacts to technology from solar storms. | NASA Earth
