The maps above, featured in our January 9, 2016 Image of the Day, show soil composition across the United States (bottom) and the space available for water to reside within those soil types (top). Douglas Miller—a soil, informatics, and remote sensing expert at Penn State—compiled the dataset on which the map is based (soil characteristics for the conterminous United States, or […]
Each month at the Earth Observatory, we publish a new satellite puzzler to challenge your remote sensing and image interpretation skills. But this December, a bit of mirth and mischief got into us. (“I could say ‘Elves,’ but it’s not elves really…”) See, we have this great new image gallery — Reading the ABCs from […]
The November 2015 puzzler turned out to perplex many of our readers. That’s no surprise; the scene shows less than 20 kilometers of Canada’s longest river—the Mackenzie. The Mackenzie River flows for more than 4,000 kilometers, and drains a basin that spans one-fifth of Canada’s total land area. Each year, the Mackenzie delivers about 325 […]
Cassie Freund is the program director of the Gunung Palung Orangutan Conservation Program, an orangutan protection project in Indonesia. While working on our latest feature story, we asked her what life was like in West Kalimantan during the 2015 fire season, when smoke blanketed parts of Borneo and Sumatra. Peat deposits, El Niño weather, and agricultural activity converged to […]
Earth Observatory has a pretty small staff — seven people — for a daily publication. There are a lot of other folks inside and outside of NASA who help us find and tell stories, but one man stands out from the rest. We might not be able to bring you a new Image of the Day, […]
Every month on Earth Matters, we offer a puzzling satellite image. The November 2015 puzzler is above. Your challenge is to use the comments section to tell us what part of the world we are looking at, when the image was acquired, what the image shows, and why the scene is interesting. How to answer. Your answer can be a few […]
Congratulations to Shadab Raza, a geologist with Oil and Natural Gas Corporation Limited, for being the first reader to decipher the location of our October Puzzler, Xinjiang in western China. Jonathan Aul followed up later in the day with the exact coordinates. “Roughly 41.6 N, 80.7 E, approximately 10-15 km south of Bozidunxiang, Wensu, Aksu, Xinjiang Province, China.” In researching […]
Usually, comic book heroes wear tight pants and have superhuman strength. In the new educational manga Raindrop Tales from NASA, one of the heroes (Mizu-chan) evaporates water with her hair. The other (GPM) rides on a 3,900-kilogram satellite that observes rain and snow. Look carefully at the art in the screenshots above, and you will find some […]
