Last calendar week NASA released a spectacular 'Black Marble' ikon of the globe from space. The ikon differs from NASA's famous Blue Marble ikon of the globe inwards that it shows the public at night. In this persuasion alone the lights of the Earth's cities tin endure seen.
Earth at Night 2012 overlays the Black Marble ikon on tiptop of Google Maps. The map is illuminating inwards to a greater extent than than 1 way. It helps to demonstrate the place of Earth's major urban centres, it is useful to astronomers inwards showing areas amongst high levels of calorie-free pollution as well as it too glaringly shows how much to a greater extent than calorie-free pollution at that spot is inwards the northern hemisphere than the south.
One affair missing from the map is the might to link to specific locations. NASA's globe Observatory wrote an interesting article on the lights that tin endure observed inwards sparsely populated North Dakota (search for Williston, ND on the map). The argue for all those lights is that the expanse is dwelling to the Bakken shale formation, where crude production is booming.
