Seen close up at the scale of a dust mite or from as far as the upper atmosphere, the life on our planet organizes into remarkably beautiful forms. Thanks to NASA, some wonderful examples of the larger scenes have been organized into a new ebook and ipad app.

Richat-Structure-Mauritania


According to NASA: “Viewed from space, the Richat Structure forms a conspicuous 50-kilometer-wide bull’s-eye on the Maur Adrar Desert in the African country of Mauritania. Described by some as looking like an outsized fossil, the feature has become a landmark for astronauts. Although it resembles an impact crater, the structure formed when a volcanic dome hardened and gradually eroded, exposing the onion-like layers of rock. In this 2001 Landsat 7 image, desert sands appear white and pale yellow at the top left and lower right corners of the scene. Less sandy, rocky areas are green, and volcanic rocks are blue.”
