Satellite Captures "Black Marble" View of Earth at Night...

Source: Reuters

Almost 40 years to the day after the Apollo 17 crew snapped the famed "blue marble" image of Earth floating in space on December 7, 1972, NASA has unveiled "black marble" video views of the planet by night.

The cloud-free pictures, taken with a high-resolution visible and infrared imager aboard a NASA and National Oceanic and Atmospheric Administration satellite, capture the night lights of Earth in unprecedented detail.

The sensor can capture the equivalent of three low-light images simultaneously, giving researchers the opportunity to study Earth's atmosphere, land and oceans at night.

"It's very high-quality data," NOAA scientist Christopher Elvidge told reporters at the American Geophysical Union conference in San Francisco...

Just because we choose to live outside cities doesn't make us "nobody". We're just people who prefer lives without high crime and pollution.

accounts for that. Roads (with lights) were established along the straight property lines. To see from space these clear lines of ownership of earth is surreal.

38. Northwest Ordinance of 1787

http://en.wikipedia.org/wiki/Northwest_Ordinance

When passed in New York in 1787, the Northwest Ordinance showed the influence of Jefferson. It called for dividing the territory into gridded townships, so that once the lands were surveyed, they could be sold to individuals and speculative land companies. This would provide both a new source of federal government revenue and an orderly pattern for future settlement.

OK, I'll confess, I'm a sometime Portlandian...but I use 20w compact fluorescents. Nobody's perfect, and none of us are good.

46. I first heard the word...

... Calif..nicator about 20 years ago when I moved from California (Bay Area) to Oregon. Even back then I think the term was used with a certain fondness. Still is - we love our neighbors to the south. No offense intended, I hope none taken. You do have a lot of lights though.

My favorite recent comment about California and sex was made by Geoffrey Nunberg, who is a professor at Berkeley and author of the book Assent of the A-Word: Assholism the First 65 Years. In the preface he says something like (I couldn't find the exact quote):

I come from Berkeley, where we will defend to the death your right to do whatever you want in the privacy of your bedroom, as long as you don't smoke afterward.


Hey, what's so funny about peace, love, and understanding?

24. I'm impressed with the darkness in the West, not the light in the East.

The area around the fire lookout tower that I staff between May and October is incredibly dark, but I knew that. In fact, I plan on doing a whole lot more night photography in the high desert wilderness (of Oregon) this coming fire season.

And then overlaid a map of the US. I think you're right, it is the oil fields up there.

I was in Bismark last year and talked to people that said the Williston area is a industrial town now 24 hours a day.
