I especially like the sharp line of the Riviera (some nice all-night parties must be going on there <img alt="" class="inlineimg" src="/images/smilies/smiley.gif" style="border:0px solid;" title=":)">) and along the shoreline of Egypt.<br><br><br><br>
What's up with Australia? <img alt="" class="inlineimg" src="/images/smilies/grin.gif" style="border:0px solid;" title=":D">

it's interesting and kindof neat in a way ..... but as someone who was once really into astronomy (and backyard viewing) , all this wasted light is annoying as hell for dark skies. I'd much rather see the stars like people used to see them than the handful seen from a normal city <img alt="" class="inlineimg" src="/images/smilies/wink3.gif" style="border:0px solid;" title=";)"><br><br><br><br>
Plus, this represents billions of dollars annually in wasted electricity. Most lights (including streetlamps, billboard illumination ...etc) is ineffeiciently designed and much light escapes to the sides or up to the sky even.<br><br><br><br>
All of this wasted electricity is made by consuming resources. Rather than deal with problems like this, governments want more power when if they simply replaced current outdoor lighting with efficient designs, they could save a vast amount of power Some cities have started replacing with more efficient lighting arrangements mainly by the pressure of astronomy groups who have shown how much money can be saved)<br><br><br><br>
It's also interesting to see the concentrations of humans (although some dark areas may be populated but just by people without arificial lighting)

neat in one way, but entirely depressing in another. Just goes to show what the proliferation of human kind has done to the natural world.....

My reaction was the same as yours. And from an aesthetic point of view, I find the natural night beautiful, and am always saddened by the fact that you have to go to remote spots to get a sense of it, as well as to see the stars.

"where's canada?!"<br><br><br><br><br><br>
Well the US is pretty well lit up. Canada is mostly the unlit area above that LOL ;-) except near the Canada/ US border. It's amazing how very little of the northern parts of Ontario and Quebec (and other northern areas) are lit up ... most of the people there are near the US/canada border

I don't think that's the shoreline of Egypt, Oatmeal, I think it's the Nile Valley. I think there is some hydro-electric project on the Nile.

What I found interesting is that it looks like mostly every inch of India is populated, and electrified, while China has its lights concenrated in only specific regions, and has less lights. I know both countries have large total populations, but I don't know what the relative population densities are, in various areas of the 2 countries. Does the lack of light in china reflect lack of pop, or lack of electricity per capita?<br><br><br><br>
I guess the Himilayas have a low population density.

Wow, you can actually follow the roads and rivers through some countries! I love to see the pinpricks of all those little islands in the oceans. <img alt="" class="inlineimg" src="/images/smilies/smiley.gif" style="border:0px solid;" title=":)"><br><br><br><br>
It is a big waste of energy I have to agree. But it is also aesthetically pleasing.

Yep, we have to travel far and wide to find good dark sky to observe...to much glow. <img alt="" class="inlineimg" src="/images/smilies/sad.gif" style="border:0px solid;" title=":(">

slynny, if it depresses you too much, you could always move. <img alt="" class="inlineimg" src="/images/smilies/tongue3.gif" style="border:0px solid;" title=":p"><br><br><br><br>
I really enjoy going home because there is absolutely no light to obstruct the sky. Very pretty.<br><br><br><br>
What I find interesting is how easily one can make out the shape of India, and how desolate Tibet and Western China are portrayed to be.<br><br><br><br>
Australia seems nearly deserted, even along the coasts where I would assume it would look more like American and Europe.<br><br><br><br>
I also like how clearly Thailands borders are marked compared to the four countries it boarders.<br><br><br><br>
I never realized how sparse most of Russia was, and the opposite about northern Scandinavia.<br><br><br><br>
Most of the Hawaiian islands are easily distinguishable.
