While on ISS, astronaut Reid Wiseman captured and tweeted a picture that captured night time picture of the Gulf of Thailand, including a vast area of green lights, distinct from the white, yellow and orange lights of adjacent cities. Reid wrote "Bangkok is the bright city. The green lights outside the city? No idea… " but others did know: it was many fishing boats with green fishing light attractors. [more inside]
We tend to think of blogs that showcase large images as a phenomenon of the past few years. But NASA's Earth Observatory has been posting its Image of the Day since April 1999 (when its first "large" image available for download was a 214 KB jpeg of the North Pole). Now, Image of the Day has downloads of images in multiple formats, most of which measure in megabytes, not kilobytes, and these stunning images of the earth's surface give context to the human activity down below: a toxic spill in Hungary, wildfires in Mexico, the growth of a coal mine in West Virginia, agriculture in Brazil, snowmelt flooding in Fargo, North Dakota, last year's oil spill in the Gulf of Mexico, artificial islands in Dubai, the aftermath of Japan's recent tsunami.
Inspired by its 10th anniversary, the Earth Observatory has pulled together a special series of NASA satellite images documenting how the world has changed. From these images, Wired Science has made 5 videos, presenting convenient time-lapse views of the world changing (mainly) because of human actions. Watch the urbanization of Dubai, specifically the growth of Palm Jumeirah. See the Aral Sea dry up - once the fourth largest lake, down to 10 percent of its original size (marked by the thin black line in the video) by 2007. View the clearing the Amazon, as observed from above the state of Rondônia in western Brazil. Behold the return of Mesopotamia's Wetlands, now in the process of being restored from near total destruction under the regime of Saddam Hussein. Witness the impact of drought on Southern Utah's Lake Powell, where water level dropped from 20 million to 8 million acre-feet from 2000 to 2005.
