I set up dual monitors at home and set
this NASA image as the background on one desktop.
Once I had this JPG expanded across both monitors and after I roamed around this composite photo for a while, one thing -- fact? observation? -- jumped out at me.
A future beer to the first person to report what I spotted.

You mean, like, apart from it already having been shown to be a fake
(EDIT: no, wait -- got it confused with a similar image; this one is probably not the fake one), and the entire planet being dark all at the same time?
Still pretty cool regardless!
Cheers!

Oh, cool! There's some kind of large phantom circle on the top left of the image -- most visible when scrolling the image left <--> right repeatedly. What's with that?
Cheers

Re: Image popquiz, My geography s&*$#s - 18/12/2005 02:25
I don't think I ever realized that Bermuda was so far north.
That wheel of lights in Alaska is wild - even seems to have a geographic center.
edit: my guess...
It's not the fact that in the US the mercury vapor street light is a thing of the past and that sodium vapor lamps have a definite orange tint.
Or to say it directly, the color of the light being shown is somewhat inaccurate.
I've always liked this image, being in the electric utility business.
I re-studied it, and all I can come up with is that South America seems a lot more to the "East" than North America above it than I remembered from my school days...
Even though I've never been there, I always think of a flight to Brazil as a flight "down" but it is really quite a bit to the East (and not even underneath the US at all).
Oh well, that's my observation....

My observations:
Africa's a pretty desolate place, devoid of a lot of nighttime lighting. So's Australia, for the most part. Stating the obvious, of course.
The other thing that stands out every time I see one of these is the stark contrast between North and South Korea...

Alright, I'll take a couple of shots at it, but you really didn't give us enough of a clue. There are quite a few things to notice on this image:
1. The American Midwest has almost a "grid" of cities, almost undoubtedly arising from proximity to grain elevators. Transport cost of grain would drive the development of towns at some interval.
2. Most of the lights are near water, with the earliest developed coastlines a solid outline of lights: the Nile, Italy's coast (the whole Med, really). Not a big surprise, since that's where the population centers are because that's how people used to get around. Actually, come to think of it, why is the Nile a solid white line?
3. You can see some of the settlement routes of lands by light density, particularly in Russia and N America.
4. The North Slope appears to have more candlepower than the rest of Alaska.
5. Humans are practically dripping off of this little spherical rock.
6. Outdoor folks in the continental US can give up on their silly ideas that they go to any "wilderness" areas.
7. Disease, poverty, infant mortality, short life expectancy and probably bad smell are inversely correllated to candlepower (again, no big suprise, since this is basically an "infrastructure map").
My best guess: what the hell is up with the Nile River?

Cool. I hadn't noticed that. Did you notice the Nile?

Re: Image popquiz - 18/12/2005 15:34
Was it:
The Nile is lit up as bright as New York City, the UK, and Japan?
(after reading the thread, I guess I'm not the first to notice)
The former Soviet Union seems to have fully lit cross country highways?
Huge Iceland produces less light than two tiny islands off of Madagascar?

Those super-high resolution images are cool. Thanks for the link.
I knew that comment would tweak some people. I love the outdoors, especially remote mountain areas. There are places where you can be 50 miles, maybe even a bit more, from the nearest road in the lower 48. It's wonderful to go to one of those places.
Going to Alaska forever changed my opinion of what a wilderness is. The most remote area in the continental US is like a suburb compared to "bush Alaska". It's just a completely staggering, mind-blowing experience. It's wilderness, where you can very easily disappear and never come back and you are very aware you are not the top of the food chain. It is just HUGE and the ground is being born right before your eyes. You SEE these immense and eternal geological processes right before your eyes and you are swallowed up by it all.
I was exaggerating in my original post. There are some very remote, dangerous and beautiful places in the lower 48. But Alaska was just... I can't even put it in words. It's just not the same category somehow. It was emotionally overwhelming. Staggering. Well, I give up. Words can't explain it.

TigerJimmy-
Go read some
Robert Service. You'll feel better.
I've not been to AK, but will some day.
