[A]way from the cities, much of the night light observed by the NASA-NOAA Suomi NPP satellite in these images comes from wildfires.

This has been confirmed by other data collected by the satellite.

Because different areas burned at different times when the satellite passed over, the cumulative result in the composite view gives the appearance of a massive blaze. These fires are temporary features, in contrast to cities which are always there.

Always, but not forever.
