Our Earth As Art is a joint project from the USGS and NASA. With that in mind, I bet you can guess it involves satellite images of the Earth. I was going to put up one of the several images of craters that give a stunning reminder of the dangers of meteor impacts, but then I came across this…
This gorgeous view is an ‘icefall’ off Lambert Glacier in Antarctica. From the website:
The Lambert Glacier in Antarctica is the world’s largest glacier. The focal point of this image is an icefall that feeds into the Lambert glacier from the vast ice sheet covering the polar plateau. Ice flows like water, albeit much more slowly. Cracks can be seen in this icefall as it bends and twists on its slow-motion descent 1300 feet (400 meters) to the glacier below.
Each of the images contains a description and a link to a much larger, printer-quality image. And best of all, they’re all free to use as long as you include proper credit.
