Every year since 1972 NASA has released a photo of Earth taken from space called "Blue Marble". For this years edition NASA decided to raise the bar a little. They used a new satellite that was launched into orbit on October 28th, 2011. The satellite, named Suomi NPP, captured numerous photos of Earth taken this January 4th for use in a composite photo. The resulting image is a 64 Megapixel masterpiece that trumps any previous "Blue Marble" photo in resolution. Below is the image along with a link to the much larger sized version on Flickr.
