The Blue Marble
This spectacular “blue marble” image is the most detailed true-color image of the entire Earth to date. Using a collection of satellite-based observations, scientists and visualizers stitched together months of observations of the land surface, oceans, sea ice, and clouds into a seamless, true-color mosaic of every square kilometer (.386 square mile) of our planet. Much of the information contained in this image came from a single source, NASA’s MODIS satellite, flying over 700 km above the Earth onboard the Terra satellite.
