When the sun goes down, the lights of human activity shine bright.
NASA scientists have just released the first new global map of Earth at night since 2012.
The VIIRS instrument on board the NASA-NOAA Suomi NPP satellite captures a high-resolution view of...
city lights...
boats on the water...
how people follow geography...
population patterns...
The new global map of night lights is a composite image
but later this year NASA scientists will release the first daily night lights data
allowing scientists to better aid disaster response and study energy use.
