We have been used to see NASA's 64-megapixel "Blue Marble" photos of the Earth. But now a Russian weather satellite has taken a 121-megapixel image of our fragile Earth, making it the most detailed photo yet. The satellite is stationed on a fixed located over 35000 kilometers above the Indian Ocean and takes a full image of Earth every 30 minutes. The resolution is one kilometer per pixel.
The photo portrays our Earth a bit differently from what we are used to. The rust color that dominates the photo is not desert; it's actually vegetation from forests. The vegetation has been turned into this orange colour because the camera on the weather satellite combines data from three visible and one infrared wavelengths of light.
