My Husband is a Great Astronaut
'Cause He Took Up Space in School

Check the link below...This is really a sight to behold.
The image is a panoramic view of the world from the new space station. It is a night photo with the lights clearly indicating the populated areas. You can scroll East-West and North-South.

Note that Canada's population is almost exclusively along the U.S. border. Moving east to Europe, there is a high population concentration along the Mediterranean Coast. It's easy to spot London, Paris, Stockholm and Vienna. Check out the development of Israel compared to the rest of the Arab countries. Note the Nile River and the rest of the "Dark Continent.” After the Nile, the lights don't come on again until Johannesburg. Look at the Australian Outback and the Trans-Siberian Rail Route. Moving east, the most striking observation is the difference between North and South Korea. Note the density of Japan.

What a piece of photography. It is an absolutely awesome picture of the Earth taken from the International Space Station a while back on a perfect night with no obscuring atmospheric conditions. Click here:
