Composite Of Earth At Night 467
crmartin writes "Today's Astronomy Picture of the Day is an incredible composite image of Earth from space at night. Actually a composite from many pictures from the Defense Meteorological Satellites Program (DMSP), it's like a skeletal view of the Earth in tiny lights. If you really like it, there are hi-res images up to a 40 megabyte TIFF."

After the fall of the Soviet Union, most of the buddy-buddy relationships with other communist countries were scratched and it turned into "every man for themselves".
North Korea used to have a constant supply of oil and coal and other energy needs from Russia, but this was abruptly terminated when Russia started saying "Er, you gotta pay full price now". The North Koreans had no cash to pay with, and thus began the rapid spiralling decline of all their energy production, transport, manufacturing and most importantly, food production. Food production in particular was a double-edged sword, needing not only oil to harvest and transport food, but also petroleum products and energy to produce fertiliser for use in North Korea's poor soil. With most of the country starving, and most machinery lying idle and rusting, things have been getting exponentially worse. They now have peasants tilling fields by hand, emaciated, underfed, with no chance of anything changing, unless they join the army, where they are emaciated, underfed and using rifles.
With little or nothing to trade with, North Korea has resorted to high-profit, (relatively) low-staffing-requirements industries like missiles, nuclear power and weapons, and (possibly) any other sorts of chemical or bio weapons to fund their dismal little empire.
Thus we now have them in a position where they have nothing to lose, and a little bitter and twisted.
To the US's credit, there were attempts to try and help Pyongyang out of this dead-end situation, by offering assistance in building reactors that were more efficient and would not produce weapons-grade materials. Unfortunatley, the Clinton administration never came good with their promises, and then the Bush administration came into power and... well, you know the rest. With the likes of John "Deputy Dawg" Bolton doing negotiations with them it's a small miracle South Korea or Japan aren't small burning heaps by now. That's if NK actually do have any nukes. Who knows... the entire government is crazy and senile, so it's hard to guess what they are doing or thinking.

Whether or not you meant to imply this, I think its worth emphasizing that it is the actions of the North Korea government that has damned the nation. Perhaps the influence of China and the Soviets wasn't quite NK's fault, the past dozen year or so resulted in the marked improvement of many post-Soviet satellite states. The North Koreans government ill management of agricultural resources, ill management of foreign relations, and their massive expenditure of money on their idle million man army, consuming one third of their GDP in supporting their army and developing weapons.

Re:Alien landing sight... (Score:4, Insightful)
An interesting question. Depends on the goals of the mission, I suspect.
A couple of profiles thrown off the top of my head:
- Make contact with global leaders
Assuming the aliens make judgments in the same way we do, I would go for either Eastern USA, Western Europe or Japan. If an assumption is made of global government, Eastern USA looks better developed so I would aim for there. If the working assumption is continental governments, there seems to be a greater degree of centralisation in Western Europe, so I'd head for either Madrid or Paris, figuring that one of those two is likely to be the European administration centre. Probably Paris, due to its more central location.
- Study the behaviour of the technology possessing inhabitants of this world
I'd head for an area on the edge of a bright patch, but far enough away that I'm likely to be able to go unnoticed. West China, East Russia, and North Africa all look quite appealing, with little to distinguish between them. I'd probably visit all three, on the basis that there might be regional variation in behaviour.

Now, taking this into consideration, the photo will yield more information. You can, for instance, quite clearly trace the route of the Trans-Siberian Railway (the narrow strip of lights running through most of Russia). In the US, the Western part was settled (by the Europeans, that is) much later than the Eastern part; as a consequence, the transportation infrastructure is less developed and it really shows (there are probably also differences in the landscape -- a city is more likely to be built in the plains that in the Great Rocky Mountains).

I dunno, I wouldn't say transportation is less developed in the US west, just developed later and rooted in different technology, mainly automobiles.
