NASA.gov has a cool composite night time photo on display at their site. It's a huge photo -- 6646 x 4430 pixels at 5.5 MB. Click to see it in full size. Click the thumbnail on the right to see it in 1200 x 800.
Everyone will want to look at his/her hometown up close. But after that, note a couple of things.
The first one is political. The Northeast sure is giving off a lot of light. Those are politically blue regions and likely to contain residents who are more inclined to believe in and advocate for the position that energy consumption causes global warming. Maybe all that light is anecdotal evidence that the man-made global warming theory is yesterday's cause.
The second is how the lights seem to make trails along the interstate highways connecting the big cities. This isn't an especially brilliant observation, and we've all known that an interstate highway can make or break a small community. But it's made obvious by all those glowing little spots along the paths between the big cities.
