Beautiful Images From NASA’s Landsats
40 YEARS WANDERING THE SKIES
• For four decades, the Landsat program has been documenting Earth from space. Satellites gather light from both visible andinvisible parts of the electromagnetic spectrum to craft detailed images including human, biological, and geological details. • Source: http://discovermagazine.com/photos/24-beautiful-images-earth-nasalandsat
Blooming in the Deep The winner of the Earth as Art contest certainly deserves its #1 position. Around Gotland, Sweden's largest island, phytoplankton form green whorls in the dark sea.The tiny plants reached this visible level of growth after currents dragged nutrients from the water's depths to its surface.
Face or Lake? Lake Eyre sits in the northern desert region of SouthAustralia, a primarily arid state. Although one of the world's largest internally draining systems empties into the lake, Eyre fills up completely only a few times every hundred years. When full, it'sthe largest lake in Australia. But when the water levels are low, as in this image, it looks more like a creepy face foaming at the mouth.
Across the Sea of Sand This picture could be an abstractpainting--but those yellow stripes are sand dunes, not paint. This is a picture of Erg Iguidi, a Saharan "sand sea" that stretches from Algeria to Mauritania. An erg is a sheet of constantly shiftingsand--in fact, ergs contain 85 percent of the moving sand on Earth. From far above, Erg Iguidi seems to be composed of wispy, delicate strands of sand, but don't be fooled: its individual dunes can bemore than third of a mile high and wide.
Tossed, Turned, and Tangled The left part looks like an unfortunately pixelated photo, but the square shapes are actually towns and fields around theMississippi River. This Landsat image, located on the Arkansas-Mississippi border, shows the twists, turns, and oxbows of North America's biggest river system
