OT: Astronomy Picture of the Day

[Kamog]

It's fascinating that the lights at night indicate the locations with the most population: Eastern U.S., Western Europe, Japan are brightest. It's easily seen that there's way more people living in U.S. than in Canada.

Somehow they edited out all the clouds and the daytime areas by combining multiple images, and the picture is actually from August 2002 if you look at the big image, not October 2006.
