Earlier this week, NASA unveiled an image titled “Blue Marble” and dubbed it the most amazing high definition image of Earth. The image was captured with the Visible/Infrared Imager Radiometer Suite (VIIRS) instrument aboard NASA’s most recently launched Earth-observing satellite, Suomi NPP. This composite image uses a number of swaths of the Earth’s surface taken on January 4, 2012.
The full resolution image is a stunning 8,000×8,000 pixels! I have taken NASA’s image and made some minor edits: a global curves adjustment, a saturation boost, and sharpened the image. Click on the image above to download the full resolution image. Makes for a great wallpaper!
