Congratulations to Joe Clark for being the first to solve our June puzzler. The answer was the Salar de Arizaro in Argentina’s Salta province. Though once bathed in water, the landscape is now bone dry due to evaporation, baking sunlight, and fierce winds. Read more about it in the image of the day we published […]
Every month on Earth Matters, we offer a puzzling satellite image. The June 2014 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 […]

We do have a few Trekkies on staff, but we didn’t actually have a Star Trek communicator in mind when we selected the May Puzzler. Nor were we trying to puzzle you by showing something from under a microscope. However, we did intend for the May puzzler to be tough because last month it was solved […]
When the Minute 319 “pulse flow” began in March 2014, it was not clear whether the effort would be enough to reconnect the Colorado River with the Sea of Cortez. Some hydrologists thought there might be just enough water; others were less optimistic. It turns out the optimists were right, though just barely. For […]
Every month we offer a puzzling satellite image here on Earth Matters. The April 2014 puzzler is above. Your challenge is to use the comments section to tell us what the image shows, what part of the world we are looking at, when the image was acquired, and why the scene is interesting. How to answer. Your answer […]
Scientists involved in the Minute 319 “pulse flow” say the effort has achieved its main objective: delivering water to special ecological restoration zones along the Colorado River. While cottonwood and willows have retreated from most areas due to a lack of water, conservation groups including the Sonoran Institute and Pronatura Noroeste have been working to […]
Congratulations to Earth Matters reader Mike G. for being the first to solve our April Puzzler! As Mike pointed out, this image shows granite outcrops in Yosemite National Park. Over on Facebook, Cooper Girard was the first to get the location; he also sagely noted that Yosemite’s landscape is the product of a granitic pluton […]

The Earth Observing-1 (EO-1) satellite was orbiting at an altitude of about 700 kilometers (400 miles) when it captured our April 11 Image of the Day — a nadir view of Kilauea’s Kahaualeʻa 2 lava flow creeping through forests northeast of Pu’u ’O’o crater. Much closer to the surface, the U.S. Geological Survey monitors the lava flow with helicopter […]
