Bushfires lighting up Australia;

These backwoods conflagrations appear so colossal that they outshine the city lights of Sydney, Melbourne, Perth and other Australian metropolises. But that’s partly due to an optical illusion created by the way this image was generated. The blackened Australia above is actually a composite of Suomi NPP satellite photos taken over 22 days in April and October.

Explains NASA:

Fires and other lights that were detected on one day were integrated into the composite, multi-day picture despite being temporary phenomena. Because different lands burned at different times that the satellite passed over, the cumulative result is the appearance of a massive blaze. But while the cities are fixed, the fires were temporary, moveable features. The night lights data set is a scientific work in progress, and the maps will be refined and improved over time.
