Today's NASA Picture of the Day
is a reprise of the famous "Earthlights" image of two years ago, probably updated
with new component photographs showing further spread of electricity, urban srawl,
and humanity into the dark regions. It's interesting to compare the NASA image
with one showing Population
Density, looking for the places where electrical output and population density
don't necessarily coincide, like North Korea.
