The 121-megapixel photo of Planet Earth

The largest single-shot photo of our planet, Earth, was created out of Russia's geostationary Elektro-L No. 1 weather sattelite, 22,369 miles away,  or 36,000 kilometers.

The image, sized 121 megapizels with resolution of 1 kilometer per pixel, is the actual whole disk image of our planet. The images were obtained on May 14-20 of last year.

Elektro-L combines four different wavelengths of light, including infrared wavelengths to capture the image. The reason why parts of Earth that are supposed to be green turn into brown is because infrared light is used to see plants.

Take a look at the "Blue Marble" shot here.
