Great Image!  Thanks Mike.

I too found the sharp contrat of N. Korea to S. Korea interesting.  Note
there are no lights on in Antartica? 

You might look at Alaska in the far upper left of the image.  There are
four large light/heat (?) spots.  For me Anchorage (pop 250,000) and
Fairbanks (60,000) were easy to recognise.  What surprized me was the large
spot just to the SW of Anchorage (and most southern of the large spots)
which represents where I live (area pop 20,000)...I guess the lights of the
refinery and offshore platforms is why.  The most northern spot is
obviously Prudhoe Bay oil field...they light the area 24-hours a day over a
linear 50 miles east-west just a few miles below the arctic ocean.  I would
agree this might be infrared imagery vs visible light.

I will save this one...many hours of interesting exploring.  Just think
what ET would think looking at this!
