Colorful new view of Earth from space is revealed ....!!!!!!!!!

This new shot — showing never before seen color and detail — is one single image at 121 megapixels (0.62 miles per pixel). The image comes courtesy of Russia's Elektro-L geostationary weather satellite located 36,000 kilometers above the equator taking a picture of the entire planet every 30 minutes. The beautiful colors are somewhat surprising, with the dark orange or rust colors actually representing the vegetation around the globe. So what's behind the unusual colors? The scientists operating the Elektro-L mixed various light wavelengths; they used three reflected sunlight bands, and two near infrared bands. The three sunlight bands simulate the colors you'd see in conventional pictures; it's the near infrared that picks up on vegetation since plants reflect in near infrared as well as green. The other unusual thing about this image? It is a single shot where as according to James Drake — who processed the Elektro-L photo — the iconic "Blue Marble" shot of Earth is actually made out of a combination of images stitched together.
